0. INTRODUCTION =============== o This document provides information on various Classic Doom, Ultimate Doom and Doom II games, and compares the game-console and handheld versions to the original PC editions, and to each other.

o Unless otherwise noted, all Doom (Doom 1) and Doom II games covered in this document are "Classic" Doom games, running (or simulating to some degree) a version of the "id Tech 1" game engine. This was the engine used in the first PC Doom game, and various subsequent Doom/Doom II titles and products prior to the release of Doom 3 in 2004.

o In this document, for purposes of comparison, Doom 64 (for Nintendo 64) is considered a Classic Doom game. While the map levels, graphics, audio, and some aspects of gameplay are very different from the equivalent things in the original PC games, Doom 64 does use a modified id Tech 1 engine, and shares many similarities with the PC Classic Doom games.

o Apple Macintosh ("Mac") and other computer-based editions of the PC Doom games exist, however they are identical in most aspects to the PC games and so are generally not addressed in this document. Other editions of Classic Doom/Doom II games not addressed here may be included in future updates.

o This document does not cover the "Final Doom" or "Master Levels" games/ mapsets for PC and various consoles. A similar document comparing these games can be accessed at: http://classicdoom.com/fdoomcmp.htm

o In the game descriptions included in this document, "Pros" are notable features of the indicated game version, some of which may set it above other versions covered here; "Cons" are generally features that existed in the original PC game(s) but are missing from the indicated version, or may otherwise cause a version to be rated below other versions covered here; "Miscellaneous" notes cover those features which do not necessarily fall under the other categories.

o This document is 79 characters wide, and is best viewed in a monospaced font. The master HTML version is located here: http://classicdoom.com/doomcomp.htm The master text version is located here: http://classicdoom.com/doomcomp.txt

1. CLASSIC DOOM GAMES: GENERAL ============================== o All (Classic) Doom/Doom II games in this document feature these basic game elements:

           |Shotgun        |Shotgun shells (group)|Medikit
           |               |                      |Radiation suit/shield
           |               |                      |Security Armor (green)
           |               |                      |Skull Key
           |               |                      |Soul Sphere/Supercharge
           |               |                      |Spiritual Armor bonus
           |               |                      |Stimpack

Notes: These elements exist in all Doom games including Nintendo 64 Doom 64 (which, unlike other console versions, is not a copy of an original PC game). "Monsters" include enemy types found in all Doom, Ultimate Doom, and Doom II games. Doom 64, and every Doom II game (or Episode) will also include these monster/enemy types: Arachnotron, Hell Knight, Mancubus, and Pain Elemental. In Doom 64, the pink "Demon" monster is referred to as a "Bull Demon". Note that not all monsters, items, etc. appear in all games at all difficulty levels. Also, some elements found on a given map during a single-player game may be absent from the same map during a multiplayer game, and vice versa. In Sega 32X Doom, a BFG 9000 weapon is only available when using cheat codes. For more about Doom cheat codes, access: http://classicdoom.com/doomcode.htm

o In all Doom/Doom II games, a player character may walk, turn, run, "jump" (run across small gaps), and side-step/strafe. In almost all Doom games, these maneuvers can be done both in first-person mode, and while the Automap screen is displayed.

o All Doom/Doom II games can experience speed fluctuations during gameplay. (This is most noticeable with early game-console ports.) In general, overall game speed will drop/rise with an increase/decrease in sprites and textures displayed on the screen.

o The following are limitations in all console and handheld Doom/Doom II games: Deathmatch games cannot include monsters; No in-game ability to import external map levels, customized graphics or sound effects; No way to adjust graphics resolution for a given screen size; Cannot place numerical markings on the Automap.

o Many non-computer Doom/Doom II games exclude some of the maps that exist in the original PC games, and/or include maps not found in the PC games. (Some game-console versions also have new hidden exits added to some map levels.) Because of this, the exact playing order of map levels may differ from that of the comparable PC game.

o In all Doom games, monsters can turn and/or move in any one of at least 8 lateral directions. In the Super Nintendo and Sega 32X games, monsters often appear to be walking backwards, or "crab-walking" sideways, because artwork is supplied only for their forward-facing surfaces. (No sprites are included to give the appearance of turning or facing away from the player.)

o Many console Doom games allow cheats to be invoked with an ordinary gamepad/ controller. Various cheats may also be loaded into many console/handheld Doom games with separately sold devices (such as a Game Genie or Game Shark) that plug into the game system.

2. COMPUTER-BASED DOOM/DOOM II GAMES ==================================== o Various IBM-PC 486 computers, and PC-compatible 486 and Pentium computers, were used as the test systems for the PC games described in this document (version 1.9 of PC Ultimate Doom and version 1.9 of PC Doom II: Hell on Earth were tested, as well as various earlier versions of all PC Doom and Doom II games). For testing multiplayer games, these computers were connected to similar systems via various network and/or modem connections.

o Pros: In general, more features and options, and greater versatility than all game-console or handheld versions of Doom or Doom II. 2 players may play simultaneously via modem connection; Up to 4 may play via network connection. On a modern PC, gameplay is somewhat faster/smoother than in most console/ handheld versions. Ability to use and configure a variety of input devices (keyboard, mouse, joystick, gamepad, etc.) for game play. Doom II-based PC games include more monster types than are available in many console/handheld Doom or Doom II games. A game in progress may be saved at any point (to any of several save-game slots) and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.). Supports 9 screen sizes, which also allows the first-person view to be expanded to fill the entire screen. Deathmatch games may include monsters. PC Doom 1's entire first Episode is still available as shareware. Thousands of external map levels are available for use with these games. Built-in ability to record or watch single-player or multiplayer gameplay sessions. Later PC Doom/Doom II game releases include extensive documentation and reference material with the software. Separate utilities exist which allow players to create or edit new map levels, new artwork and/or new sounds for existing Doom/Doom II games. A variety of free third-party Doom engines have been released, which add improved graphics, better multiplayer support and other features to the retail PC games. Wide variety of built-in cheat codes.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC Doom/Doom II games, including areas on some levels where players may become inadvertently trapped, a program bug that creates nearly-intangible monsters, a bug that can allow a player character to become stuck partially inside solid objects when reloading saved games, and a bug in Doom II where the game can crash if a map-30 save-game file is reloaded.

o Miscellaneous: Games by id Software. Disk or CD format; Also available via direct download through some retail sites. Decent graphics resolution and quality; Very good in some hardware/software configurations. The commercial edition of Doom ("Doom 1") for the PC includes 27 map levels, divided into three 9-map Episodes. A later reissue of the game, titled "The Ultimate Doom: Thy Flesh Consumed", includes the original three Episodes and a newer fourth Episode which includes 9 more map levels. Doom II ("Doom 2: Hell on Earth") for the PC has 32 map levels built in, and adds new monsters and a double-barrelled shotgun not found in Doom 1 or Ultimate Doom. Occasionally when a Pain Elemental monster (in Doom II) dies, the Lost Souls generated by its explosion may be flung through nearby walls, where they may become trapped (this has little effect on the game, since Lost Souls do not count towards a Kills score). Unlike some console/handheld versions, a player can only cycle between fist and chain saw while a Berserk power-up is in effect.

3. SONY PLAYSTATION (PS1) DOOM ============================== o A Sony PlayStation, model SCPH-1001, equipped with one standard PlayStation controller (model SCPH-1080), was used as the test system for the Custom PlayStation Edition of Doom described in this document. For testing multiplayer games, the system was connected to an identical system via the PlayStation Link cable (model SCPH-1040).

o Pros: Features most of the map levels (or equivalents) from the PC games "The Ultimate Doom" and "Doom II" (Doom 2: Hell on Earth). Large variety of monster types (17) compared to many other game-console and handheld versions. Link ability (for compatible systems) allows 2-player Deathmatch and Co-Op games. The first-person view and status bar combination fills the entire display space on the screen (some other console versions of the same era do not support this). Map level, skill level, health, armor, weapon and ammo information is translated to a password code which is given after successful completion of each map level (some other console Doom games cannot save such information externally). The last password entered or generated on the password screen may be re-entered with a single button press (useful when, for example, a player is killed and wishes to restart on the same map with a non-default status). Extensive controller customizing is allowed (the Fire button can swap functions with Speed button or Activate button, etc.). PS1 Doom games can also be played (single-player, only) on PS2 and PS3 consoles via backward compatibility.

o Cons: The 24 maps from Jaguar Doom are incorporated (with minor edits) into the 33-map "Ultimate Doom" Episode (most of the maps in Atari Jaguar Doom are edited/simplified versions of the original PC Doom maps). Minor errors exist in a few map levels (secret room impossible to access, difficulty in picking up an item, etc.). From powering up the PlayStation, there is a relatively long wait (over a minute) before the player can actually start playing. Game cannot make use of a memory card (sold separately). Game does not save controller or sound configuration settings. Some monster/enemy types from PC Doom II are missing from this version, including the Arch-Vile, "SS Officer", and the "Baphomet"/Boss entity. No crushing ceilings in the "Ultimate Doom" maps. Occasionally, objects in the foreground are partially overlaid by background wall or floor textures. Weapons are cyclic-access only (although weapon choices may be cycled while the game is paused). The status bar can only display the ammo level of the currently selected weapon (in PC and some other games, all ammo levels for all weapons can be displayed at all times). All of the built-in cheat codes are rather long and complex (for example, an invincibility cheat code is 3 button-presses on the Jaguar, 5 on the PC, 10 on the PlayStation). No "Gamma Correction" feature or equivalent.

o Miscellaneous: Port by id Software and Williams Entertainment, Inc. CD format. 59 map levels, 8 of which are not found in PC Doom/Doom II games. Good graphics resolution and quality. Gameplay speed is adequate, but is somewhat slower than a PC Doom/Doom II game played on a modern computer. Game information stored in a password code may be inaccurate (health, armor and ammo level numbers tend to be rounded). Features music tracks (and other background audio effects) not found in PC Doom games. Features new colored lighting effects. Health potions and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1% in the PC games). In PC Doom II, the two shotgun types are both represented as weapon 3 in the status bar; In PS1 Doom, the shotgun types are separated into weapons 3 and 4. No "Nightmare" skill level. Some Doom II monsters (Heavy Weapon Dude, Revenant, etc.) appear in the "Ultimate Doom" maps when playing at the highest skill level ("Ultra Violence"). Monster and weapon sounds tend to differ from the sounds used in the PC games. In this game, "blurred" objects are translucent and faded, but otherwise maintain their normal colors and surface features (in the PC games, "blurred" objects, when visible, are a translucent gray, with a flat, flowing/scrambled surface). Another version of the Spectre appears in this game: the "Nightmare Spectre", which appears visibly darker, and is harder to kill than the normal Spectre. The Nightmare Spectre is a not a 1-to-1 replacement for the missing Arch-Vile monster. Very tall rooms/areas from equivalent maps in the PC game(s) are lower in this version. An "X-ray vision" cheat code not found in the PC games is included. An animated "wall of fire" exterior background is used in some map levels. Some monsters and monster projectiles tend to move slower than their PC-game counterparts. Graphics "noise" may sometimes be seen along the top or bottom edges of walls. On occasion, the "marine face" in the status bar explodes when the player character dies. On occasion, when a Pain Elemental monster dies, the Lost Souls generated by its explosion may be flung through nearby walls, where they may become trapped. Lost Souls that are trapped behind walls may still be visible, but may be impossible to kill (this normally has no effect on the game, since Lost Souls do not count towards a Kills score). The voice effect that accompanies "victory text" is not heard if Music Volume is turned down. Some monsters on the original PC maps are replaced with different monsters on the equivalent maps in this version. In 2-player games, both player characters wear a green uniform. In Cooperative games, Frags are not indicated in the tally screens. The "WOLFENSTEIN" and "GROSSE" secret map levels from PC Doom II do not appear in this game. The "Commander Keen" character from PC Doom II is not included. The "Lots of Goodies" cheat code will not add keys if they are not necessary.

o PC Ultimate Doom and PlayStation Doom map level comparison:

Notes: Map equivalency is based on general map layouts, not map names. The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. The PS1 "HELL KEEP" map does not match the PC "HELL KEEP" map. (It does, however, match an equivalent map in the Saturn, Jaguar, 3DO and GBA Doom 1 games.)

o PC Doom II (Doom 2: Hell on Earth) and PlayStation Doom map level comparison:

Notes: In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally screens, and "'O' OF DESTRUCTION!" in the Automap.

4. SEGA SATURN DOOM =================== o A Sega Saturn unit, model MK-80000A, equipped with one standard Sega Saturn Control Pad (model MK-80116), was used as the test system for the NTSC Sega Saturn Doom game described in this document.

o Pros: Features most of the map levels (or equivalents) from the PC games "The Ultimate Doom" and "Doom II" (Doom 2: Hell on Earth). Large variety of monster types (17) compared to many other game-console and handheld versions. The first-person view and status bar combination fills the entire display space on the screen (some other console versions of the same era do not support this). Map level, skill level, health, armor, weapon and ammo information is translated to a password code which is given after successful completion of each map level (some other console Doom games cannot save such information externally). The last password entered or generated on the password screen may be re-entered with a single button press (useful when, for example, a player is killed and wishes to restart on the same map with a non-default status). Extensive controller customizing is allowed (the Fire button can swap functions with Speed button or Activate button, etc.).

o Cons: No multiplayer ability (NTSC edition). Overall game speed is slower/ choppier in than in the PC games and some other game-console versions. The 24 maps from Jaguar Doom are incorporated (with minor edits) into the 33-map "Ultimate Doom" Episode (most of the maps in Atari Jaguar Doom are edited/ simplified versions of the original PC Doom maps). Minor errors exist in a few map levels (secret room impossible to access, difficulty in picking up an item, etc.). Game cannot make use of a memory cartridge (sold separately). This game does not save controller or sound/music configuration settings. "Strafing"/side-stepping tends to be somewhat slower here than in many other versions. Weapons are cyclic-access only, and can only be cycled in one direction. Some monster/enemy types from PC Doom II are missing from this version, including the Arch-Vile, "SS Officer", and the "Baphomet"/Boss entity. No crushing ceilings in the "Ultimate Doom" maps. The status bar can only display the ammo level of the currently selected weapon (in PC and some other game versions, all ammo levels for all weapons can be displayed at all times). Background objects or surfaces may sometimes overlap foreground objects/surfaces. No "Gamma Correction" feature or equivalent.

o Miscellaneous: Port by Rage Software (NTSC edition). CD format. 59 map levels, 8 of which are not found in PC Doom/Doom II games. Decent graphics resolution and quality. Sega Saturn Doom is very similar to the earlier PlayStation (PS1) Doom game (map levels, monsters, sound effects, music, and passwords used are all virtually identical). Saturn Doom graphics are similar to the PS1 Doom graphics, but lack some of the enhanced lighting and color effects used in PS1 Doom. Game information stored in a password code may be inaccurate (health, armor and ammo level numbers tend to be rounded). Health potions and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1% in the PC games). In PC Doom II, the two shotgun types are both represented as weapon 3 in the status bar; In Saturn Doom, the shotgun types are separated into weapons 3 and 4. No "Nightmare" skill level. Some Doom II monsters (Heavy Weapon Dude, Revenant, etc.) appear in the "Ultimate Doom" maps when playing at the highest skill level ("Ultra Violence"). Monster and weapon sounds tend to differ from the sounds used in equivalent PC games. In this game, "blurred" objects are translucent and faded, but otherwise maintain their normal colors and surface features (in the PC games, "blurred" objects, when visible, are a translucent gray, with a flat, flowing/scrambled surface). A second version of the Spectre appears in this game: the "Nightmare Spectre", which looks like the normal Spectre, but is harder to kill. The Nightmare Spectre is a not a 1-to-1 replacement for the missing Arch-Vile monster. Very tall rooms/areas from equivalent maps in the PC game(s) are lower in this version. Some monsters and monster projectiles tend to move slower than their PC-game counterparts. The player character's basic running speed (compared to other moving objects in the environment) is somewhat faster here than in other versions. In general, each weapon's "rapid-fire" rate is higher here than in other Doom games. Graphics "noise" may sometimes be seen along the top or bottom edges of walls. On occasion, when a Pain Elemental monster dies, the Lost Souls generated by its explosion may be flung through nearby walls, where they may become trapped. Lost Souls trapped behind walls may still be visible, but may be impossible to kill (this has little effect on the game, since Lost Souls do not count towards a Kills score). The voice effect that accompanies "victory text" is not heard if Music Volume is turned down. Some monsters on the original PC maps are replaced with different monsters on the equivalent maps in this version. Player may select stereo (default) or monophonic audio. Stereo sounds may occasionally phase-shift, giving false impressions of sound sources (for example, during continuous firing of the player's chaingun, some of the reports may seem to originate from a point to the player's left or right). Pausing the game does not interrupt music. "DEMO" will flash on the screen while demo games are shown. 3 demo games are shown during Attract mode (including demos from 2 "secret" map levels), then the third demo is repeated once before cycling back to the first. In most Doom/Doom II games that end victoriously with a "parade" (or "Cast of Characters"), the parade repeats until the player resets or restarts the game; In Saturn Doom, the parade runs through one time, and then the game returns to the Main Menu screen. The "WOLFENSTEIN" and "GROSSE" secret map levels from PC Doom II do not appear in this game. The "Commander Keen" character from PC Doom II is not included. The "Lots of Goodies" cheat code will not add keys if they are not necessary.

o PC Ultimate Doom and Saturn Doom map level comparison:

Notes: Map equivalency is based on general map layouts, not map names. The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. The Saturn "HELL KEEP" map does not match the PC "HELL KEEP" map. (It does, however, match an equivalent map in the PS1, Jaguar, 3DO and GBA Doom 1 games.)

o PC Doom II (Doom 2: Hell on Earth) and Saturn Doom map level comparison:

Notes: In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally screens, and "'O' OF DESTRUCTION!" in the Automap.

5. NINTENDO 64 DOOM 64 ====================== o Note that Doom 64, unlike other console/handheld Doom games, was not a direct port or conversion of an existing PC Doom game. It does, however, share many of the same features found in all other Classic Doom/Doom II games.

o A Nintendo 64 Control Deck, model NUS-001, equipped with one standard Nintendo 64 Controller (model NUS-005), was used as the test system for the Doom 64 game described in this document.

o Pros: Comparatively smooth, high-resolution graphics produced through dynamic antialiasing. The "pixelation" effect (a drop in graphics resolution seen in other Doom games as the player character approaches a surface or object) is notably reduced here. Features some new graphical effects (fog/mist, fading objects, animated skies, etc.). First-person view fills the entire space on the screen (with or without the "status bar" displayed). The "bar" of the "status bar" is invisible: only the numerals used for health, ammo and armor, and icons used for keys, will actually obstruct any part of the first-person view. The status bar may be switched off, allowing only the first-person view to fill the screen. Map level, skill level, health, armor, weapon and ammo information is translated to a password code which is given after successful completion of each map level (some other console Doom games cannot save such information externally). On the password screen, the last password entered or generated may be re-entered with a single button press (useful when, for example, a player is killed and wishes to restart on the same map with a non-default status). Doom 64 can make use of a "Controller Pak" (a separately-sold memory cartridge), allowing the storage and retrieval of up to 16 game passwords. Built-in screen brightness adjustment option, somewhat similar to the "Gamma Correction" feature in PC Doom games. The Automap is dual-mode, allowing the player to view the map with a detailed textured floor (using an Area's actual floor textures), or view the map as a plain (PC-Doom style) untextured Automap. Extensive controller customizing is allowed (the Fire button can swap functions with Speed button or Activate button, etc.), including the ability to choose and/or modify any of 5 preset configurations. The player can move within the game using the controller's directional-pad buttons, and/or the controller's built-in joystick. The player character can rotate at varying speeds: turning slowly using controller buttons, marginally faster using the joystick, or very fast with the joystick if the "Controller Stick Sensitivity" is increased through a setting under the game's Options Menu. The game provides a feature for "centering" the position of the game screen on the display device, allowing horizontal and vertical adjustments. Game messages (such as "PICKED UP A BOX OF SHELLS") may be toggled on or off, as can be done in the PC Doom games.

o Cons: No multiplayer ability. On some display devices the first-person view may seem too dark, and/or the status bar data may be difficult to read, even when the game's brightness level is set to maximum. Occasionally objects in the foreground are partially overlaid by background wall or floor textures. Weapons are cyclic-access only (but may be cycled in both directions). Game does not save controller, display, or sound configuration settings. Although joystick-based turning speed can be greatly increased through a setting under the game's Options Menu, D-pad (or button-based) turning speed cannot. The status bar can only display the ammo level of the currently selected weapon (in PC and some other game versions, all ammo levels for all weapons can be displayed at all times). Once in Automap mode, a player must cycle through both Automap styles to return to the first-person view (this can be done almost instantaneously if desired, but must be done every time the Automap is accessed). At 16 characters long, the passwords are somewhat cumbersome to enter, unless they are stored in a separately-sold Controller Pak memory cartridge. The Zombieman and Shotgun Guy enemy types are very similar in appearance, and may be indistinguishable during combat. The delay between a player character's death and subsequent resurrection is longer here than in other Doom games.

o Miscellaneous: Game by Midway Home Entertainment, Inc. and id Software. Cartridge format. 32 map levels, none of which are found in PC Doom/Doom II games. Gameplay speed is adequate, but some aspects of a player character's motion (such as running speed) may be marginally slower here than in a PC Doom/Doom II game played on a modern computer. More monster/enemy variety in this game than in most Doom 1-based games (several of the Doom 64 monster types are based on PC Doom II types). With some new features and completely re-worked graphics, the "look and feel" of this game bears only a distant resemblance to all other Doom games. All enemies have a modified appearance, and in some cases are only vaguely similar to their counterparts in other Doom or Doom II games. Virtually all objects and surface textures have been changed from their original designs, including weapons, power-ups, walls, floors, ceilings, switches and teleporters. Map levels may have structures that simulate crossing paths at different heights (such as a solid "bridge" that a player can walk over or under), and similar map features which are not found in other Doom games. Graphics, overall, tend to be darker here than in most other versions. Features new music tracks (and other background audio effects) not found in the PC games. Some features appear in this game that appear in no other Doom or Doom II game, including flat horizontally-sliding surfaces, wall-mounted monitors that can be used to view distant parts of the map, automated traps that launch projectiles, etc. Doom 64 features a new "Boss" monster (referred to in the game as the "Mother of all Demons") which is not found in any other Doom game. The Spider Mastermind monster found in most other Doom games is not included. Another version of the Imp appears in this game: the "Nightmare Imp", which is semi-translucent, darker, and faster than the normal Imp, and launches high-velocity fireballs. Arachnotrons fire twin, side-by-side plasma bursts (versus single-stream bursts in all other games). Pain Elemental monsters can release 2 Lost Souls at a time (versus a maximum of 1 at a time in all other games). Lost Souls are semi-translucent in this game, and tend to attack more quickly than their counterparts in other games. In Doom 64, Baron-Of-Hell projectiles can injure Hell Knights, and vice-versa (in other Doom/Doom II games, both projectiles are harmless to both monsters). The "Demon" monster (a pink, muscular, hunched-over, biting monster), is referred to as a "Bull Demon" in the game's printed manual. In this game a Spectre Demon will be opaque until it detects a player character, whereupon it becomes translucent. If a translucent Spectre Demon is killed, its body becomes opaque. A new laser-type weapon appears in this game, and uses the same "cell" ammunition as a plasma rifle or BFG 9000. Doom 64 includes a unique type of power-up (referred to in this document as a "Demon Artifact") which acts both as an enhancement for the new laser weapon, and as a special key/activator for use within the game's final map level. Demon Artifacts have an appearance somewhat similar to the demon/pentagram graphic that is used both in the game's tally screens and on the cover of the game's manual. When any Demon Artifact is picked up, an icon representing that particular Artifact appears at the lower-right corner of the Automap screen. A double-barrelled "Super Shotgun" (similar to the weapon found in Doom II games) appears in this game. The double-barrelled shotgun and the rocket launcher both have a "kick" when firing, giving a slight backwards push against the player character. In this game, the plasma rifle tends to make a continuous buzzing noise whenever it is selected as the current weapon. In this game, the chain saw has a pair of blades, side by side (versus a single blade in all other Doom games). In all other Doom games, only players and monsters may be teleported from place to place; In Doom 64, other objects (power-ups, weapons, and structures) may also be moved from place to place, or fade in and out of existence. Occasionally monsters will spontaneously "fade in" to a location on the current map (an effect which is similar to teleportation). Game information stored in a password code may be inaccurate (health, armor and ammo level numbers tend to be rounded). Monster and weapon sounds tend to differ from the sounds used in the PC games (in fact most sound effects are identical to those used in the PlayStation/PS1 Doom games, released prior to Doom 64). The sound effect used in PS1 Doom for an item re-spawning during a Deathmatch game is used in this game to indicate that a monster or item/object is "fading into" (or "spawning into") a nearby location. In this game, "blurred" objects are translucent and faded, but otherwise maintain their normal colors and surface features (in the PC games, "blurred" objects, when visible, are a translucent gray, with a flat, flowing/scrambled surface). Explosive barrels are not mentioned in the game manual, but do appear in this game, as they do in all other Doom games. The "marine face", seen in the status bar of all other Doom/Doom II games, is not in the status bar in this game. "Secret areas" are usually announced (via on-screen messages) as a player character enters them. While walking/running in Automap mode, the player icon does not turn to change direction; instead, the Automap rotates around the icon, which is always facing north. In this game, the "radiation shield" power-up appears as a green "biohazard" symbol, instead of as the white, full-body "radiation suit" seen in all other Doom games. The physical location of an item on a given map can vary with the skill level that the map is played on (for example, the blue keycard in the STAGING AREA map is in an open area when the game is played on skill 1, but is located in a small, closed room on skill 4). Doom 64 uses skill level names unique among console Doom games: "BE GENTLE!", "BRING IT ON!", "I OWN DOOM!", and "WATCH ME DIE!". Some surfaces with 1-way transparency are used in this game (a feature missing from most other non-computer versions). In Doom 64, entering a valid map 1 password, or using a special locked exit on map 32, will reveal a hidden "Features Menu", which allows access to various cheat functions. On occasion, the first-person display will shake as an indication of a major change in the current map level (changes in the map's topography, structures, etc.). When firing a weapon, the first-person view can jump or vibrate with the weapon's recoil. Every 30 seconds of idle time after a player character dies, the game will display one of 12 "taunts" (such as "HAHAHAHA!" or "HAVE YOU HAD ENOUGH?"). Both shotgun types are reloaded without the relatively elaborate reloading animation seen in all other Doom/ Doom II games (however the weapon reloading times remain comparable to those of the other games). In most Doom and Doom II games the plasma rifle is swung up and to the side for a moment at the end of a firing sequence; in this game the weapon always faces forward.

Notes: The map levels in Doom 64 match none of those found in any other Doom or Doom II game.

6. ATARI JAGUAR DOOM ==================== o An Atari Jaguar 64-Bit Interactive Multimedia System, equipped with one standard Jaguar controller, was used as the test system for the Atari Jaguar Doom game described in this document. For testing multiplayer games, the system was hooked to an identical system via the Jaglink Interface cable. Multiplayer games were then tested with identical systems hooked together via Catbox interface devices (sold separately by ICD, Inc.).

o Pros: 2-player ability (although multiplayer function may be unstable). The first-person view and status bar combination fills the entire display space on the screen (some other console versions of the same era do not support this). Some controller customizing is allowed (the Fire button can swap functions with Speed button or Activate button, etc.). Memory built into the game cartridge will automatically store controller configuration settings, the sound volume setting, the current skill level setting, and also stores the map level numbers of all Areas that were successfully conquered (except Area 24). When first starting up the game, a player may choose to start play on any of 23 map levels previously conquered (this is a quick process, as there are no passwords to keep or re-enter), and may choose a different skill level to play it at. During a game in progress, weapons are direct-access. The built-in cheat codes may be entered quickly and easily (for example, an invincibility cheat code is 3 button-presses on the Jaguar, 5 on the PC, 10 on the PlayStation). The Jaguar Doom game comes with a plastic overlay which fits into the top of the game controller, providing labels and weapon icons for the buttons on the controller's keypad.

o Cons: Most of the maps in this game are edited/simplified versions of the equivalent PC Doom 1 maps. Games in progress cannot be saved (but a player may start a new game on any of 23 map levels previously conquered). As stated in the printed manual, occasional "Network Errors" can occur during Deathmatch and Cooperative games, causing the game in progress to suddenly start over again on the current map. Only 7 monster types in the game (tying with the Sega 32X and GBA Doom 1 games for least variety). No Spectre Demon. No Cyberdemon or Spider Mastermind monsters. No Blur Artifacts. No light-amplification visors. No crushing ceilings. No music during gameplay. Somewhat lower graphics resolution or quality than some other large-screen console Doom versions. The status bar can only display the ammo level of the currently selected weapon (in PC and other game versions, all ammo levels for all weapons can be displayed at all times).

o Miscellaneous: Port by id Software. Cartridge format. 24 map levels, 2 of which are not found in PC Doom games. Adequate graphics resolution and quality. Gameplay speed is adequate, but can be somewhat slower than a PC Doom game played on a modern computer. This game's mapset, in whole or in part, also appears in the PlayStation, Saturn, 3DO, Sega 32X and GBA Doom 1 games or Episodes. Rocket and barrel explosions can penetrate relatively far through solid walls and doors (allowing a player to kill some enemies without ever directly encountering them). Health potions and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1% in the PC games). Picking up an Invulnerability Artifact tints the screen bluish-pink, as opposed to the white-out effect seen in many other versions. In 2-player games, both player characters wear a green uniform. In Deathmatch games, the Frag counts for both players are displayed in each player's status bar. Corrosive floors (slime, etc.) will decrease a player's health quickly (faster in this version of Doom than in most other versions running at a comparable skill level). When the "Happy Ammo" cheat code is used, the player attains an ammo level of 500 rounds for every weapon (versus a specific individual ammo level for each weapon in the PC games). Game manual is written in English, French, German. Game manual states that cartridge memory will not accept more than 100,000 changes to stored information (however this would still allow, for example, 50 changes a day for more than 5 years).

o PC Doom and Atari Jaguar Doom map level comparison:

Notes: Map equivalency is based on general map layouts, not map names. The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. The Jaguar "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No Jaguar equivalent exists for the PC "DIS" map. The Jaguar "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map. (It does, however, match the "TOWER OF BABEL" map in the 3DO and GBA Doom 1 games, and the "HELL GATE" map in the PS1 and Saturn games.) The Jaguar "HELL KEEP" map does not match the PC "HELL KEEP" map. (It does, however, match an equivalent map in the PS1, Saturn, 3DO and GBA Doom 1 games.)

7. 3DO (PANASONIC AND OTHERS) DOOM ================================== o A Panasonic REAL 3DO Interactive Multiplayer, model FZ-1, equipped with one standard Panasonic 3DO controller (model FZ-JP1X), was used as the test system for the 3DO Doom game described in this document.

o Pros: Some controller customizing allowed (the Fire button can swap functions with Speed button or Activate button, etc.). Ability to choose between 4 window sizes (or 6, when using a cheat code) for the first-person view. 3DO system memory automatically stores controller configuration settings, the sound volume setting, the current skill level setting, the selected window size for the first-person view, and also stores the map level numbers of all Areas that were successfully conquered (except Area 24). When first starting up the game, a player may choose to start play on any of 23 map levels previously conquered (this is a quick process, as there are no passwords to keep or re-enter), and may choose a different skill level to play it at.

o Cons: Games in progress cannot be saved (but a player may start a new game on any of 23 map levels previously conquered). No multiplayer ability. Overall game speed can be very choppy, and animation noticeably slows down and speeds up with variances in the number of on-screen textures and sprites. This game uses the Jaguar Doom mapset (most of the maps in Jaguar Doom are edited/ simplified versions of the original PC Doom maps), and includes no other maps. No Cyberdemon or Spider Mastermind monsters. No light-amplification visors. No crushing ceilings. Weapons are cyclic-access only. First-person view does not fill the entire space above the status bar. Game does not utilize all available display space on the screen. The status bar can only display the ammo level of the currently selected weapon (in PC and some other versions, all ammo levels for all weapons can be displayed at all times).

o Miscellaneous: Port by Logicware and Art Data Interactive, Inc. CD format. 24 map levels, 2 of which are not found in PC Doom games. Adequate graphics resolution and quality. Gameplay speed, overall, is below the average speed of most other Doom games. Features many of the music tracks from PC Doom, re-mastered with new and more distinctive instrumentation. A built-in cheat code allows the first-person view window to be expanded two more times beyond the default maximum size (however, larger windows further slow down the game). The game box for 3DO Doom advertises "full screen display", and the first-person view is indeed maximized within a window; but the window itself (when expanded to any size) is always bordered by static artwork. Rocket and barrel explosions can penetrate relatively far through solid walls and doors (allowing a player to kill some monsters without ever directly encountering them). Health potions and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1% in the PC games). In this game, "blurred" objects are a translucent gray with a plain, flat surface (in the PC games, "blurred" objects, when visible, are a translucent gray, with a flat, flowing/scrambled surface). If the "Map All Things" cheat code is used, monster orientations are not indicated as they are in all other game versions that support this cheat code; all object indicators point in the same direction. The "marine face" in the status bar always explodes whenever the player character dies. Music from the first map level accompanies the tally screens. No "Attract mode"; no demo games. When the "Happy Ammo" cheat code is used, the player attains an ammo level of 500 rounds for every weapon (versus a specific ammo level for each weapon in the PC games).

o PC Doom and 3DO Doom map level comparison:

Notes: Map equivalency is based on general map layouts, not map names. The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. The 3DO "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No 3DO equivalent exists for the PC "DIS" map. The 3DO "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map. (It does, however, match the "TOWER OF BABEL" map in the Jaguar and GBA Doom 1 games, and the "HELL GATE" map in the PS1 and Saturn games.) The 3DO "HELL KEEP" map does not match the PC "HELL KEEP" map. (It does, however, match an equivalent map in the PS1, Saturn, Jaguar and GBA Doom 1 games.)

8. SUPER NINTENDO DOOM ====================== o A Super NES ("SNES") Control Deck, model SNS-001, equipped with one standard Super NES controller (model SNS-005), was used as the test system for the SNES Doom game described in this document. For testing multiplayer games, the system was connected to various similar systems via the X Band network, using a Catapult X Band modem device (model 00100).

o Pros: The basic map layouts tend to match the equivalent PC-Doom 1 maps with above-average accuracy (higher accuracy, overall, than is found in most other early console versions). Simplified 2-player online Deathmatch ability via an X Band Network connection. SNES Doom includes both the Spider Mastermind and Cyberdemon monsters from the original PC games (one or both of these are missing from GBA Doom 1 and some large-format console versions). The Automap is actively updated at all times, whether displayed or not (in most other Doom/Doom II games, the Automap will not update while displayed). A player character with 200% health will not automatically pick up a Soul Sphere on contact (in most other Doom/Doom II games, a Soul Sphere is always picked up on contact). Weapon choices can be cycled while the game is paused.

o Cons: Games in progress cannot be saved. Comparatively low-resolution graphics (most noticeable with distant objects); lowest overall resolution of all large-screen Doom games. Some control "lag" (a delay between controller input and a reaction in-game). Cannot play Episodes 2 or 3 using low skill levels. For multiplayer games, a separately-sold "X Band" modem device, and a subscription to the X Band Network, is/was required for each player's game system. Cooperative games are not supported. Deathmatch games are scaled down in this version (no sound effects, items do not re-spawn, an enemy player character simply disappears from the Area when killed, exiting a map level displays the main menu, where both players must select which map to restart the game on, and weapons, ammo, etc., cannot be carried between map levels). Most vertical surfaces tend to be somewhat "sticky", occasionally slowing or halting the player character on contact. A player's shotgun in SNES Doom can only affect a single target when fired (in other Doom games, multiple targets in close proximity can be affected). Shotguns or ammo clips dropped by killed enemies do not appear on the floor/ground. A player may still pick up weapons after ammo levels are at maximum (for example, a player may pick up multiple shotguns, even after reaching the maximum carry limit of 100 shells). Newly acquired weapons or ammo items contain a standard amount of ammunition at all skill levels (in the PC games, the standard amount of ammo for each item is doubled when playing at the lowest or highest skill levels). No controller customizing allowed. Weapons are cyclic-access only (although weapons may be cycled while the game is paused), and weapon choices can only cycle in one direction. No real textures for ceilings or floors (including corrosives and teleporters). Monsters can only display a front side (and are essentially always facing towards the player). No Spectre Demon. Cannot save game configuration settings. Game does not utilize all available display space on the screen. Sounds from events at medium or long ranges may be truncated, or may not be played. Although monsters can hurt each other, they cannot deliberately fight with each other. No screen-flash warning as an Invulnerability Artifact or radiation suit begins to wear out. When the player character is attacked, the "marine face" in the status bar does not indicate direction of attack (as it does in other Doom games). Unlike other Doom versions, pivoting and strafing functions in this game are mutually exclusive. The status bar can only display the ammo level of the currently-selected weapon (in PC and some other versions, all ammo levels for all weapons can be displayed at all times). End-of-Episode story text is not always shown when finishing Episodes at low skill levels.

o Miscellaneous: Port by Sculptured Software, Inc. Cartridge format. 22 map levels, all of which are found in PC Doom 1. Gameplay speed is adequate, but will be slower than a PC Doom game played on a modern computer. No "Attract mode"; no demo games. A bug in the game can allow the player to instantly acquire additional weapons once a chain saw has been picked up. In most Doom versions, a killed player restarts a map level with 100% health, 0% armor, a pistol and 50 bullets; but in SNES Doom, a killed player restarts with 100% health, and whatever armor, weapons and ammo that the player originally brought into the level. While walking/running in Automap mode, the player icon does not turn to change direction; instead, the Automap rotates around the icon, which is always facing north (this is also how Automap "scrolling" is handled). Some monsters are easier to kill than their counterparts in other versions of the game. When cycling through weapons, the chain saw weapon slot is located between the shotgun and chaingun (in PC Doom the fist and chain saw share slot 1). Unlike other Doom games, Blur Artifacts in SNES Doom can render the player undetectable to "waiting" monsters at medium or long range; A monster that detects a player at short range can even return to "wait" mode if the player moves away. In this game, "blurred" objects are translucent and faded, but otherwise maintain their normal colors and surface features (in the PC games, "blurred" objects, when visible, are a translucent gray, with a flat, flowing/scrambled surface). Hitting the Activate/Use button can still trigger the "grunt" sound effect, even when the player character is nowhere near a wall, switch, or door. Compared to other Doom games, many sound effects in SNES Doom are mismatched with their events, or are used for multiple events (for example, a monster's "alert sound" can also be used for it's "growl" sound while patrolling). Some action sequences (such as monster deaths, explosions, etc.) use fewer frames of animation than the equivalent sequences in other Doom games. No exploding-monster effect (usually seen in PC Doom games when, for example, an Imp or Former Human is hit by a rocket). Teleportation is instantaneous, without the motion-damping effect seen in other versions. No "green spark" effect when a player or monster goes through a teleporter. Impacts of bullets or shotgun pellets on walls are not visible. No panels or switches are activated by projectile impacts, as they are in other versions. An Artifact or power-up can be picked up when the player walks over it, but can also be picked up if the player is jumping (running) through the airspace above it. A weapon icon appears in the player's status bar to show which weapon is currently held. Monster projectiles may affect monsters in ways contrary to what is seen in other Doom or Doom II games (a Cacodemon's projectiles can injure other Cacodemons, a Cyberdemon can be damaged by its own rockets, etc.). Unlike other Doom games, a Cyberdemon in SNES Doom can use a melee/scratch attack at close range (although the normal rocket-firing animation is displayed). The Cyberdemon tends to fire 2 rockets in a row, versus 3 in a row in all other versions. Cyberdemon rockets appear to fly backwards. A player's chaingun fires fewer bullets than what is indicated by the firing sound. In SNES Doom a minimal burst of chaingun fire is typically 1 bullet (with 2 reports), versus 2 bullets in most other Doom games. The plasma rifle fires its projectiles at a lower rate than in most other Doom games. A BFG 9000 will use up to 40 energy cells per shot, but can be fired when less than 40 cells remain (most Doom/Doom II games always require a minimum of 40 cells). Some projectiles move at faster speeds than in other Doom games. In most other Doom games an elevator/lift will automatically reverse if a player/monster prevents it from rising to its highest position; In the SNES game, a blocked elevator will simply halt in place, and only move again when the obstacle is removed. Crushing ceilings may not cycle upwards while a player/monster is being crushed (unlike certain crushing ceiling types in PC Doom/Doom II). Some secret doors/panels are better camouflaged in this game than in PC Doom. Players and monsters do not move laterally as a result of impacts or nearby explosions, as they do in other Doom games. Phobos/Deimos/Hell landscapes are used as the background for the tally screens between map levels, showing the player's progress through the various stages of each Episode (this art is omitted from some other non-computer Doom versions). After a player finishes Episode 2, an Episode-3 game begins automatically. Maps in Episode 3 use the same sky/background used in Episode 2 (PC Doom uses a "Hell" sky/background for Episode-3 maps). No scrolling/sliding textures, as are found in other Doom games. No built-in volume controls (but music and sound effects can be switched on/off separately). Most of the original PC Doom story text appears in this game. Both armor-vest types are referred to as "MEGAARMOR" (in other games this term is used only for the blue 200%-armor vest). No built-in cheat codes.

o PC Doom and SNES Doom map level comparison:

Notes: The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. The "E_#M#_" designators used here for SNES Doom maps are for reference only, and are not displayed in the actual game.

9. SEGA GENESIS 32X DOOM ======================== o A Sega Genesis System Console, model 1601, equipped with one standard Sega Genesis "6-button" controller (model MK-1653), and one Sega Genesis 32X module (model MK-84000A), was used as the test system for the Sega 32X Doom game described in this document.

o Pros: Player can always start a game on any of 15 map levels. The Automap is actively updated at all times, whether displayed or not (in most other Doom/ Doom II games, the Automap will not update while displayed). Some controller customizing allowed (the Fire button can swap functions with Speed button or Activate button, etc.). With a "6-button" controller attached, weapons can be accessed directly, or weapon choices can be cycled in both directions.

o Cons: Requires both a Sega Genesis system and the "32X" expansion module. This version has the least map levels of all Doom games, and most of the maps are edited/simplified versions of the original PC Doom 1 maps. Games in progress cannot be saved (but a player may always start a new game on any of 15 maps). No multiplayer ability. No BFG 9000 weapon available without using a cheat code. Monsters can only display a front side (despite the fact that screen shots on the game box and the 32X module box show side views of monsters). Only 7 monster types in the game (tying with the Jaguar and GBA Doom 1 games for least variety). No Spectre Demon. No Cyberdemon or Spider Mastermind monsters. No Blur Artifacts. No light-amplification visors. No crushing ceilings. With a standard Sega "3-button" controller, weapons are cyclic-access only, and weapon choices can be cycled in only one direction. Cannot save game configuration settings. First-person view does not fill the entire space above the status bar, and game does not utilize all available display space on the screen. Although monsters can hurt each other, they cannot deliberately fight with each other. Some rooms on some maps are inaccessible. The few built-in cheat codes can be difficult to implement (the code button combinations may have to be pressed several times before a code will take effect). The use of cheat codes can prevent access to some maps, and also prevents the game's full ending sequence from being shown. The status bar can only display the ammo level of the currently selected weapon (in PC and some other game versions, all ammo levels for all weapons can be displayed at all times). Infrequent, brief flashes of graphics "noise" may sometimes appear across the first-person view or Automap screen.

o Miscellaneous: Port by id Software. Cartridge format. 17 map levels, all of which are found in PC Doom games. Decent graphics resolution and quality. Gameplay speed is adequate, but can be somewhat slower than a PC Doom game played on a modern computer. Maps 16 and 17 can only be accessed if the game was started on map 1, and if cheat codes were not used during the game. In order to see the game's entire ending sequence, a player must start on map level 1 and play the game all the way through without using cheat codes (a game won any other way will result in the credits being shown, and then the game simply halts with a plain textured screen and a "DOS prompt"). Contrary to what is stated in the game manual, a player cannot enter map 1 from map 15; map-level sequence does not "wrap around". Rocket and barrel explosions can penetrate relatively far through solid walls and doors (allowing a player to kill some monsters without ever directly encountering them). Health potions and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1% in the PC games). Picking up an Invulnerability Artifact causes a drop in graphics chroma, as opposed to the white-out effect seen in many other versions. Picking up a Berserk Pack will cause a relatively bright, sustained flash of red, which may be mistaken for the effect seen when the player character takes sudden, heavy damage. The shotgun-loading sound is played (sometimes at very low volume) for a teleportation event, instead of the teleport sound heard in most other versions. Map level names are not used, only map numbers. Map numbers are only indicated in the tally screens, not while playing a map level. In the Automap, the player icon (an arrow) looks like the one used in the PC games, as opposed to the green triangle used in most other versions. There is an option in Automap mode to turn on a grid which overlays the map, and can be used as a reference for scale (a feature otherwise found only in the PC games). Rockets fired by the player appear to fly backwards (the nose of the rocket faces the player as the rocket moves away). All monsters, items and Artifacts located in very dark areas remain well lit at all times. Not all teleporters function (but all important ones do). Because graphics are only provided to show the front side of objects, some monsters in "wait" mode may seem blind when a player approaches them from behind (a monster will always appear to look at a player even when it is not actually facing toward the player). When the "Happy Ammo" cheat code is used, the player attains an ammo level of 500 rounds for every weapon (versus a specific ammo level for each weapon in the PC games).

o PC Doom and Sega Genesis 32X Doom map level comparison:

Notes: The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. Map level names are not used in Sega 32X Doom.

10. NINTENDO GAME BOY ADVANCE DOOM ================================== o A Nintendo Game Boy Advance, model AGB-001, and a Nintendo Game Boy Advance SP, model AGS-001, were used as test systems for the GBA Doom game described in this document. For testing multiplayer games, these system were connected to identical systems via one or more Nintendo Game Boy Advance Game Link cables (model AGB-005).

o Pros: Multiplayer link ability, allowing 2 players in Cooperative games, and 2 to 4 players in Deathmatch games. Includes 8 Deathmatch-only bonus maps not found in other commercial Doom games. Some flaws have been corrected in some maps which were copied from earlier console Doom games. A game in progress may be saved to any of 4 save-game slots in the Doom Game Pak, and save-game data includes controller, lighting and audio settings. Supports 2 lighting-style choices, "Dynamic" (normal), and "Static" (low light levels are increased, and lights that normally flash are always on). Has 6-level "Brightness" adjustment option (somewhat similar to the "Gamma Correction" feature in the PC Doom games), which controls the maximum brightness of both Dynamic and Static lighting modes. Includes an "Autorun" option (player always runs). In the status bar, current ammo levels and limits are always displayed for all weapons (in some other/earlier console Doom games, only the currently-selected weapon can have an ammo level displayed). Some controller customizing allowed (any of 6 preset button configurations may be selected).

o Cons: The original Game Boy Advance does not have built-in lighting, making games hard to view without constant external light hitting the screen at the correct angle (later GBA models, like the GBA SP, do have built-in lighting). Saved games may occasionally become corrupted, and fail to reload correctly. Cooperative games have a 2-player limit, even when 3 or more GBAs are linked. This game uses a slightly modified version of the Jaguar Doom mapset (most of the maps in Atari Jaguar Doom are edited/simplified versions of the original PC Doom maps), and has no other single-player maps. The player character can potentially become trapped behind a wall or barrier on certain maps. Only 7 monster types in the game (tying with the Jaguar and Sega 32X games for least variety). No Spectre Demon. No Cyberdemon or Spider Mastermind monsters. No Blur Artifacts. No light-amplification visors. No crushing ceilings. Weapons are cyclic-access only. In some of the preset button configurations weapon-swapping can be awkward, and weapon changes can occur unintentionally while performing certain maneuvers. Some rooms in some map levels are inaccessible. The sound effect used to indicate a player taking damage is also mistakenly used whenever a player lands unhurt after falling a short distance. Frag counts in Deathmatch games are only displayed in the Automap view. No tally screen is displayed, and no opportunity to save the game is given, when a player accesses the exit to the "MILITARY BASE" map level.

o Miscellaneous: Port by David A. Palmer Productions. Cartridge format. 32 map levels, 10 of which are not found in PC Doom games. Decent graphics resolution and quality for the GBA screen. Gameplay speed is adequate, but will be somewhat slower than a PC Doom game played on a modern computer. The game's overall speed can be affected by the built-in lighting options, where Dynamic Lighting may lower the frame-rate, and Static Lighting may raise it. No "Attract mode"; no demo games. No "Ultra-Violence" skill setting; the highest skill is "Nightmare". Player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. When monsters or players are killed, their corpses disappear after a brief delay. Monster and player blood is green instead of red. All monsters, items and Artifacts located in very dark areas remain well lit at all times. Sounds produced by distant events may be played at an undiminished volume, and/or may penetrate walls or areas that are "soundproof" in other Doom games. When a pink Demon is killed, it makes the same sound as a dying Imp (in most other Doom games, Imps and Demons will make separate sounds). No exploding-monster effect (usually seen in PC Doom games when, for example, an Imp or Former Human is hit by a rocket). Rocket and barrel explosions can penetrate relatively far through solid walls and doors (allowing a player to kill some enemies without ever directly encountering them). Teleportation is almost instantaneous, without the motion-damping effect seen in most other versions. In a reversal of the Automap coloring used in most other Doom games, GBA Doom's Automap displays "viewed" surfaces as gray lines, and "unseen" surfaces (often added to the Automap when a Computer Area Map item is acquired) are displayed in red. The Automap screen allows 5 preset zoom levels. Health potions and Spiritual Armor bonuses add 2% to a player's health or armor (versus 1% in the PC games). Picking up an Invulnerability Artifact tints the screen blue, as opposed to the white-out effect seen in many other Doom versions. In this game, muzzle flashes from player weapons do not brighten nearby surfaces, as they do in other Doom games. Unlike most other Doom games, Lost Souls are calculated in the Kills score displayed in the tally screens. The tally screen shows both the time spent on the map, and the map's Par Time. Phobos/ Deimos/Hell landscapes are used as the background for the tally screens between map levels, showing the player's progress through the various stages of each Episode (this art is omitted from some other non-computer Doom versions). The "YOU ARE HERE" indicators in the tally/landscape screens do not always point to the correct locations. When the "Happy Ammo" cheat code is used, the player attains an ammo level of 500 rounds for every weapon (versus a specific individual ammo level for each weapon in the PC games). In this game the player's fist makes an impact noise when striking a wall or other inanimate object (in most other versions, fist impacts on inanimate objects are silent).

o PC Doom and GBA Doom map level comparison:

Notes: Map equivalency is based on general map layouts, not map names. The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap. The GBA "DIS" map is equivalent to the PC "FORTRESS OF MYSTERY" map; No GBA equivalent exists for the PC "DIS" map. The GBA "TOWER OF BABEL" map does not match the PC "TOWER OF BABEL" map. (It does, however, match the "TOWER OF BABEL" map in the Jaguar and 3DO games, and the "HELL GATE" map in the PS1 and Saturn games.) The GBA "HELL'S KEEP" map does not match the PC "HELL KEEP" map. (It does, however, match an equivalent map in the PS1, Saturn, Jaguar and 3DO games.) GBA Doom maps 25 through 32 are only accessible in Deathmatch games.

11. NINTENDO GAME BOY ADVANCE DOOM II ===================================== o A Nintendo Game Boy Advance, model AGB-001, and a Nintendo Game Boy Advance SP, model AGS-001, were used as the test systems for the GBA Doom II game described in this document. For testing multiplayer games, these system were connected to identical systems via one or more Nintendo Game Boy Advance Game Link cables (model AGB-005).

o Pros: This game has more maps and monster types than the "DOOM II" Episodes of PlayStation Doom or Saturn Doom. Multiplayer link ability, allowing 2 players in Cooperative games, and 2 to 4 players in Deathmatch games. Games in progress may be saved to any of 4 save-game slots in the Doom II Game Pak, and game data includes controller, lighting and audio settings. Includes a 6-level "Gamma" adjustment option to control the overall brightness of the game screen. Controller customizing includes 4 preset button configurations, a 5-level "Sensitivity" adjustment option to control the player character's pivoting speed, and an "Always Run" option (player always runs). In the status bar, current ammo levels and ammo limits are always displayed for all weapons (in many console Doom games, only the currently selected weapon can have an ammo level displayed). The "Happy Ammo" cheat code will provide a backpack (in most other Doom games, a backpack is not provided, or a player's existing backpack is removed).

o Cons: The original Game Boy Advance does not have built-in lighting, making games hard to view without constant external light hitting the screen at the correct angle (later GBA models, like the GBA SP, do have built-in lighting). On rare occasions the game may freeze, requiring that the GBA be powered down and restarted. Occasionally when a player weapon is fired at a close target, it auto-aims toward the ceiling/sky or floor/ground. In some of the preset button configurations, weapon-swapping can be awkward, and weapon changes may occur unintentionally while performing certain maneuvers. Weapons are cyclic-access only. The auto-aim ability of monsters can remain unaffected when the player picks up a Blur Artifact. Damage to a player's armor may not always be accurately represented in the status bar. The scoring system for "Kills" is inaccurate under certain conditions (for example, unlike the PC games, GBA Doom II will count Lost Souls as score-affecting enemies, yet does not actually give credit to the player for killing them). When the player character is attacked, the "marine face" in the status bar does not indicate direction of attack (as it does in other Doom games). The Frag counts in Deathmatch games are only displayed in Automap view. Cooperative games have a 2-player limit, even when 3 or more GBAs are linked. Unlike the PC Doom games, a player's reverse-running speed is slower than forward-running speed.

o Miscellaneous: Port by Torus Games. Cartridge format. 34 map levels, all of which (in whole or in part) are found in PC Doom II: Hell on Earth. Decent graphics resolution and quality for the GBA screen. Overall gameplay speed is adequate, but is somewhat slower than a PC Doom II game played on a modern computer. No "Attract mode"; no demo games. No "Ultra-Violence" skill setting; the highest skill is "Nightmare!". Some GBA Doom II maps reflect certain features found in maps from older versions of PC Doom II. In this game some maps have minor alterations, such as elevators replacing stairs, and strategically placed walls/barriers, or deleted windows, in order to reduce the maximum number of objects that need to be drawn at any given time. Some maps in this game have major alterations, such as deleted buildings; but in general there are fewer large omissions here than in some other console/ handheld Doom II games. The PC Doom II maps INDUSTRIAL ZONE and THE CHASM are each split into 2 "half" maps in this game. When computing collision detection in this game, most non-structural objects have a comparatively narrow diameter, and this can allow some objects (such as players and/or monsters) to move very close together, or to push past one another, where they could not in PC Doom II. Unlike most other Doom games, the monsters in this game cannot open doors. Monsters and players may occasionally cross above/below one another (a player can even stand on top of a monster, which is something that does not occur in other commercial Doom games). Some monsters on some map levels are "blind" or "deaf" where equivalent monsters in the PC maps are not. A monster's "sensory range" is foreshortened in this game (monsters cannot see or hear as far as they can in PC Doom II or most other Doom games). An active monster may halt in place if enough distance accrues between the player and monster. Monsters can remain inactive even while being attacked by a player at long range. When a monster is killed, its corpse will flicker and disappear after a brief delay. Arch-Viles may resurrect killed monsters even after the monster corpses have disappeared. Mancubus monsters are not able to aim vertically, and will always launch their fireballs in a wide, predetermined pattern. Revenants will only fire homing missiles, which are smokeless (in PC Doom II, Revenants can fire 2 missile types: a smoking homing missile, and a smokeless non-homing missile). Unlike most other Doom games, monsters such as Imps or Demons cannot scratch or bite a player from very high/low adjacent areas. Floating/flying monsters may not always change altitude to attack a target, or may fail to rise again after dropping in pursuit of a target. Monsters may continue to try to attack killed players. Some monster sound effects are missing, including the walking sounds for Arachnotrons and Cyberdemons. Common bullet-firing sounds are used when the Chaingunner enemy fires (in PC Doom II, a shotgun sound is used). The sounds used during an Arch-Vile attack are reversed from sounds heard in PC Doom II (in this game, the "boom" sound of a completed attack precedes the "burning" sound of an attack in progress). Some player/monster weapons have slightly modified firing strengths or rates. Weapons tend to have less horizontal auto-aim ability, and some projectiles are "narrower", than their counterparts in PC Doom II. In GBA Doom II, a minimal burst of chaingun fire is typically 1 bullet, versus 2 bullets in most other Doom games. The function of the BFG 9000 is somewhat different here than in most other Doom games (the weapon's secondary-attack pattern and range has been altered). Bullet and shotgun pellet impact patterns differ somewhat from those in other Doom games. Monster blood is green instead of red. Player characters do not bleed when injured; the blood-spatter sprites are replaced here by "bullet puffs" (small gray sprites used for bullet or shotgun pellet impacts on solid surfaces). No exploding-monster effect (usually seen in PC Doom games when, for example, an Imp or Former Human is hit by a rocket). Rocket explosions and plasma bursts can trigger impact-activated switches (in most other Doom/Doom II games these projectiles will not affect switches). Unlike other Doom games, close-range explosions caused by player rockets will not push against the player. In this game muzzle flashes from player weapons do not brighten nearby surfaces, as they do in other versions. Unlike the PC Doom games, players can change lateral direction and speed while falling or moving through the air. Hitting the Activate/Use button can still trigger the "grunt" sound effect, even when the player character is nowhere near a wall, switch, or door. Certain messages in this game, such as "Find the switch to open this door", do not appear in other Doom games. Some surfaces with 1-way transparency are used in this game (a feature missing from many other non-computer versions). "Secret areas" are usually announced (via on-screen messages) as a player character enters them. Monsters which are killed by other monsters are not included when calculating the Kills score (in all other Doom games, monster deaths are attributed to players regardless of how the kill occurred). Newly acquired weapons or ammo items contain a doubled amount of ammunition at all skill levels (in the PC Doom games, the standard amount of ammo for each item is doubled when playing at the lowest or highest skill levels). In GBA Doom II, almost all retrievable items on a given map level are tallied in the Items score (in most other Doom/Doom II games, many retrievable item types are not tallied). Unlike PC Doom games, a player may pick up more than one Computer Map item. The tally screen shows both the time spent on the map, and the map's Par Time. All major items and power-ups will re-spawn in Deathmatch, including Invulnerability Artifacts, Blur Artifacts and Megaspheres (in PC Doom games, not all item types will re-spawn). Some symbols and images from the secret maps in PC Doom II are altered in the equivalent maps here. Objects suspended from ceilings (bodies or body parts on chains, etc.) do not appear, as they do in the equivalent PC Doom II maps. In most Doom/Doom II games the plasma rifle is swung up and to the side for a moment at the end of its firing sequence; in this game the weapon always faces forward. Some item names are misspelled (MEDIKIT spelled MEDKIT), or are spelled differently in different places (ARMOR/ARMOUR).

o PC Doom II (Doom 2: Hell on Earth) and GBA Doom II map level comparison:

Notes: In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally screens, and "'O' OF DESTRUCTION!" in the Automap. In GBA Doom II, maps "INDUSTRIAL ZONE" and "THE CHASM" are each split into 2 separate maps (parts "A" and "B"). The map numbers used here for GBA Doom II maps are for reference only, and are not displayed in the game.

12. TAPWAVE ZODIAC DOOM II ========================== o The term "Zodiac" in this document applies to either of 2 similar handheld Tapwave devices: Zodiac 1 and Zodiac 2.

o A Tapwave Zodiac 2, model T2907USA ("first edition"), was used as the test system for the Zodiac Doom II game described in this document.

o Pros: Zodiac Doom II is a nearly direct copy of the v1.9 PC Doom II game, and so includes all of the original PC maps and monsters, and almost all of the original art, textures, music, etc. This Zodiac game has fewer changes or omissions than GBA Doom II and some other non-computer Doom/Doom II games. Decent gameplay and screen-refresh rate. A game in progress may be saved at any point and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/ dead status of all monsters on the map level, etc.). Game supports 9 screen sizes, which also allows the first-person view to be expanded to fill the entire screen. Some analog-control customization allowed ("Move sensitivity" and "Turn sensitivity" adjustment options). Includes an "Autorun" option (player always runs). Games played at "Nightmare" skill include re-spawning monsters (a feature missing from some non-computer versions).

o Cons: No multiplayer ability. Although analog-control sensitivity can be adjusted, precise movement of the player character can be difficult to maintain (for example, it can be overly easy to pivot while attempting to move in a straight line). Some infrequently-encountered flaws exist in the original commercial PC Doom II game which were ported unchecked into this game, including a program bug that creates nearly-intangible monsters, and a bug that can allow a player character to become trapped partially inside solid objects when reloading saved games. Save-game files are stored in RAM, and so are preserved only if the RAM remains powered (power can diminish even while the unit is "off"), or the files are manually copied to separate media. Weapons are cyclic-access only, and weapon choices can be cycled in only one direction. Occasional errors occur when cycling through available weapons (weapon cycle may "wrap around" at the wrong point, etc.). Map name/number is not displayed on the Automap screen.

o Miscellaneous: Port by MachineWorks NorthWest LLC. Memory-card format (SD type); formerly also available as a direct download from www.tapwave.com. 32 map levels, all of which are found in PC Doom II: Hell on Earth. No "Attract mode"; no demo games. Some sound effects in this game are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom releases, but later abandoned). Cheat codes are allowed in games played at "Nightmare" skill. A "walk through walls" cheat code is included (a cheat otherwise found only in the PC games, and Apple iOS Doom).

o PC Doom II (Doom 2: Hell on Earth) and Zodiac Doom II map level comparison:

Notes: In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally screens, and "'O' OF DESTRUCTION!" in the Automap.

13. MICROSOFT XBOX CLASSIC DOOM GAMES ===================================== o Note: This section refers to Classic Doom games for Microsoft's first Xbox console, which is sometimes referred to as the "Original Xbox" or "Old Xbox".

o The Xbox game "Doom 3: Limited Collector's Edition" includes the bonus games Ultimate Doom: Thy Flesh Consumed, and Doom II: Hell on Earth. The Xbox game "Doom 3: Resurrection of Evil" includes those same two Classic games, and an additional Master Levels game (essentially an extra mapset for Xbox Doom II). This document addresses the Classic Ultimate Doom and Doom II games for Xbox; For more information about various Master Levels games/Episodes/maps, access: http://classicdoom.com/fdoomcmp.htm

o A Microsoft Xbox, model F23-00097, equipped with one standard Xbox controller (model K04-00001), was used as the test system for the Xbox Ultimate Doom and Xbox Doom II games described in this document. For testing split-screen multiplayer games, additional controllers (K04-00001, K86-00001, third-party) were added to the system.

o Pros: The Xbox Ultimate Doom and Doom II games are nearly direct copies of the equivalent v1.9 PC games, and so include all of the original PC maps and monsters, and almost all of the original art, textures, music, etc. In general, these games have fewer changes or omissions than many other console Doom/Doom II games. Both games support split-screen Deathmatch/Cooperative gameplay for 2 to 4 players. Very fast gameplay and screen-refresh rate in both single-player and multiplayer games. Single-player games in progress may be saved at any point and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.). Games support 9 screen sizes, and the first-person view can be expanded to fill the entire screen. Games played at "Nightmare" skill will include re-spawning monsters (a feature missing from some non-computer versions).

o Cons: Some infrequently-encountered flaws exist in the original commercial PC Doom/Doom II games which were ported unchecked into these games, including areas on some maps where players may become inadvertently trapped, a program bug that creates nearly-intangible monsters, a bug that can allow a player character to become stuck partially inside solid objects when reloading saved games, and a bug in Doom II where the game can crash if a map-30 save-game file is reloaded. In addition to the flaws ported from the PC games, these Xbox games may sometimes freeze or crash where the original PC games would not. Cheat functions can be accidentally activated during play (some common gameplay actions have button-use patterns that match certain cheat codes). No controller customizing is allowed. No built-in ability to adjust sound effects volume or music volume. No ability to independently scroll the Automap (the Automap display is always in "Follow mode"). No ability to select skill level for multiplayer games; Deathmatch and Co-Op games can only be played at skill 3 ("Hurt Me Plenty"). Items do not re-spawn in Deathmatch games. Weapons are cyclic-access only (although weapon choices can be cycled in both directions). Some enemy types are not in "fast" mode in games played at "Nightmare" skill. A player cannot get a 100% Kills or Secret score on Ultimate Doom map E4M1 ("HELL BENEATH"), due to a switch that was disabled when this map was ported from PC Ultimate Doom. No "Gamma Correction" feature or equivalent (however the first-person view tends to be brighter than in some other console versions).

o Miscellaneous: Ports by Vicarious Visions. Xbox DVD format. The Ultimate Doom game contains 37 map levels, 1 of which is not found in PC Ultimate Doom; The Doom II game contains 33 map levels, 1 of which is not found in PC Doom II: Hell on Earth. Graphics resolution and quality are virtually identical to the original PC games. In "split screen" mode, the individual player screens retain the aspect ratio of a full-sized screen; As such, the first-person views do not expand to fill all available space on the display device for 2- or 3-player games. All Episodes of the Ultimate Doom game use only one sky/background texture for each map (versus a variety of backgrounds in the PC game). Music tracks in both games play at a slightly different rate than the equivalent tracks in the original PC games. When cycling through weapons in Doom II, the double-barrelled "Super Shotgun" weapon slot is located between the chain saw and fist (in PC Doom II games, both shotgun types share a weapon slot between the pistol and chaingun). The player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. In the first 3 Episodes of the Ultimate Doom game, Phobos/Deimos/Hell landscapes are used as the background for the tally screens between map levels, showing the player's progress through the various stages of each Episode (this art is omitted from some other non-computer Doom versions). Some sound effects in both games are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom releases, but later abandoned). Cheat codes are allowed in games played at "Nightmare" skill. The bonus maps in these games originally appeared earlier as third-party WAD files for the PC games.

o PC Ultimate Doom and Old/Original-Xbox Ultimate Doom map level comparison:

Notes: In both games, the Episode 3 Mission 7 map is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.

o PC Doom II (Doom 2: Hell on Earth) and Old/Original-Xbox Doom II map level comparison:

Notes: In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally screens, and "'O' OF DESTRUCTION!" in the Automap.

14. MICROSOFT XBOX 360/XBLA DOOM ================================ o "Doom" for the Xbox 360 is available in disc form, bundled in "Doom 3: BFG Edition", and may also be downloaded from the Microsoft Store (an online service for various Xbox consoles/devices). The online version is offered in 2 forms: "Free Trial", where players can try the game's first map for free, and "Full Game", a paid version where all content is unlocked.

o Although this Xbox 360 game is titled "Doom", the actual product is the 4-Episode update/reissue of Doom, called "The Ultimate Doom".

o A "Premium" Microsoft Xbox 360, model MSK-XBOX360CONSOLE(B), equipped with one standard Xbox 360 wireless controller (model X809478-001), was used as the test system for the Xbox 360 Doom game described in this document. For testing split-screen multiplayer games, additional identical controllers were added to the system. For testing online multiplayer games, the console was connected through the Xbox Live service to an identical console.

o Pros: This Xbox 360 game is a nearly direct copy of PC Ultimate Doom v1.9, and so includes all of the original PC maps and monsters, and virtually all of the original art, textures, music, etc. In general, this Xbox 360 game has fewer changes or omissions than many other console Doom/Doom II games, including the earlier Ultimate Doom port for Original Xbox (bundled with Xbox Doom 3 games). Graphics resolution for this game is higher than that of most other commercial Ultimate Doom games (including the original PC version), improving the sharpness and detail of sprites and textures at longer ranges. Supports split-screen Deathmatch and Cooperative gameplay for 2 to 4 players, and full-screen Deathmatch/Cooperative games over Xbox Live. Very fast gameplay and screen-refresh rate in both single-player and same-console multiplayer games. Single-player games in progress may be saved at any point and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.). Game supports 11 screen sizes (but does not allow the first-person view to be expanded to fill the entire screen). Games played at "Nightmare" skill include re-spawning monsters (a feature missing from some non-computer versions). Patches or updates to this product may become available online via Xbox Live. This game supports 10 save-game slots per storage device, and the storage device can be specified or changed when saving/loading games. This game can also be played on Xbox One consoles via backward compatibility.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC game which were ported unchecked into this game, including areas on some levels where players may become inadvertently trapped, and a program bug that can allow a player character to become stuck partially inside solid objects when reloading saved games. In addition to the flaws ported from the PC game, this Xbox 360 game may sometimes freeze where the original PC game would not. No controller customizing allowed. No ability to independently scroll the Automap (the Automap display is always in "Follow mode"). Online multiplayer games are currently only available to paying members of Xbox Live Gold; the free/Silver membership does not support online play. Deathmatch games are confined to single maps (exit switches/portals are deactivated). Weapons are cyclic-access only (although weapon choices can be cycled in both directions). Some enemy types are not in "fast" mode in games played at "Nightmare" skill. No "Gamma Correction" feature or equivalent (however the first-person view tends to be brighter than in some other console versions).

o Miscellaneous: Port by Nerve Software and Vicarious Visions. Available as a download (about 23 megabytes) through the Xbox Live online service. 36 map levels, all of which are found in PC Ultimate Doom. As with other Xbox Live titles, this game supports the "Achievements" system, which allows players to track various accomplishments in the game, for both themselves and other players of the game on Xbox Live. In "split screen" mode, the individual player screens retain the aspect ratio of a full-sized screen; As such, the first-person views do not expand to fill all available space on the display device for 2- or 3-player games. In Cooperative-mode games, whenever one player acquires a key, the same key appears in the inventory of all other players. A player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. In the first 3 Episodes of the game, Phobos/Deimos/Hell landscapes are used as the background for the tally screens between map levels, showing the player's progress through the various stages of each Episode (this art is omitted from some other non-computer Doom versions). Music tracks are remastered in 5.1 Surround Sound, and so sound marginally different than the equivalent tracks in the original PC game. Some sound effects in this game are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom releases, but later abandoned). No built-in cheat codes.

15. MICROSOFT XBOX 360/XBLA DOOM II =================================== o "Doom II" for Xbox 360/XBLA includes 2 games/Episodes ("Hell on Earth" and "No Rest for the Living") in a single package. This is available in disc form, bundled in "Doom 3: BFG Edition", and may also be downloaded from the Microsoft Store (an online service for various Xbox consoles/devices). The online version is offered in 2 forms: "Free Trial", where players can try the first map of either Episode for free, and "Full Game", a paid version where all content is unlocked.

o A "Premium" Microsoft Xbox 360, model MSK-XBOX360CONSOLE(B), equipped with one standard Xbox 360 wireless controller (model X809478-001), was used as the test system for the Xbox 360 Doom II game described in this document. For testing split-screen multiplayer games, additional identical controllers were added to the system. For testing online multiplayer games, the console was connected through the Xbox Live service to an identical console.

o Pros: This Xbox 360 title features a nearly direct copy of PC Doom II v1.9 (and so includes all of the original PC maps and monsters, and virtually all of the original art, textures, music, etc.), and also includes an additional and separate 9-map Episode, "No Rest for the Living". In general, Xbox 360 Doom II has fewer changes or omissions than other console/handheld Doom II games, including the Doom II port for Original Xbox (bundled with Xbox Doom 3 games). Graphics resolution for this game is higher than that of most other commercial Doom II games (including the original PC version), improving the sharpness and detail of sprites and textures at longer ranges. Supports split-screen Deathmatch and Cooperative gameplay for 2 to 4 players, and full-screen Deathmatch/Cooperative games over Xbox Live. Very fast gameplay and screen-refresh rate in both single-player and same-console multiplayer games. Single-player games in progress may be saved at any point and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.). Game supports 11 screen sizes (but does not allow the first-person view to be expanded to fill the entire screen). Games played at "Nightmare" skill include re-spawning monsters (a feature missing from some non-computer versions). Includes an "Auto-run" option (player always runs). Patches/updates to this product may become available via Xbox Live. This game supports 10 save-game slots per storage device, and the storage device can be specified or changed when saving/ loading games. Weapons are cyclic-access (in 2 directions), and some may also be accessed directly by category type (bullet, pellet, energy, etc.) via the controller's D-pad. Gameplay sessions are automatically recorded (although recordings can be flawed), and the 10 highest-scoring sessions on the Xbox Live Leaderboards are preserved, and may be watched again from the Leaderboard menu screen. This game can also be played on Xbox One consoles via backward compatibility.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC game which were ported unchecked into this game, including areas on some levels where players may become inadvertently trapped, and a program bug that can allow a player character to become stuck partially inside solid objects when reloading saved games.

No "Gamma Correction" feature or equivalent (however the first-person view tends to be brighter than in some other console versions). Recorded gameplay sessions ("demos") may de-sync when replaying, causing player characters to appear to move and shoot at random. In 2012 a re-issue of this Doom II game made changes to the "Hell on Earth" secret levels, including replacing all "SS Officer" enemies with Zombiemen, and that change can cause de-syncs in Cooperative games if both players are not using the same version of the game.

o Miscellaneous: Port and additional content by Nerve Software. Available as a download (about 35 megabytes) through the Xbox Live online service. 41 map levels, total, 32 of which are found in original PC Doom II: Hell on Earth. As with other Xbox Live titles, this game supports the "Achievements" system, which allows players to track various accomplishments in the game, for both themselves and other players of the game on Xbox Live.

A player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. Recently finished gameplay sessions on the player's Xbox 360 will temporarily replace the built-in demos that are shown during any idle time between games. Music tracks are remastered in 5.1 Surround Sound, and sound marginally different (in addition to being slower) than the equivalent tracks in the original PC game. Many sound effects in this game are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom games, but later abandoned). The red plus-shaped symbol on health power-ups has been replaced in this version by a red-and-white pill symbol. No built-in cheat codes.

o A Sony PlayStation 3 ("PS3"), model CECHK01, equipped with one standard PS3 DualShock 3 Sixaxis wireless controller (model CECHZC2U), was used as the test system for the PS3 Doom game described in this document. For testing split-screen multiplayer games, additional PS3 controllers were added to the system. For testing online multiplayer games, the console was connected through the PlayStation Network ("PSN") to an identical console.

o Pros: This PS3 game is a nearly direct copy of PC Ultimate Doom v1.9, and so includes all of the original PC maps and monsters, and virtually all of the original art, textures, music, etc. In general, this PS3 game has fewer changes or omissions than many other console Doom/Doom II games. Graphics resolution is higher than that of most other commercial Ultimate Doom games (including the original PC version), improving the sharpness and detail of sprites and textures at longer ranges. Supports split-screen Deathmatch and Cooperative gameplay for 2 to 4 players, and full-screen Deathmatch/ Cooperative games over PlayStation Network ("PSN"). Very fast gameplay and screen-refresh rate in both single-player and same-console multiplayer games. Single-player games in progress may be saved at any point and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.).

Games played at "Nightmare" skill include re-spawning monsters (a feature missing from some non-computer versions). Includes an "Always Run" option (player is always in Run mode), and an option to turn controller vibration on/off. Patches or updates to the product may become available via PlayStation Network. Game allows storage and management of a large number of save-game files (far more than other versions), and the displayed file information includes map name, Difficulty, play time, and a timestamp for the file itself. All weapons are cyclic-access (in 2 directions), and some may also be accessed directly by category type (bullet, pellet, energy, etc.) via the controller's D-pad. Deathmatch games may be set to an unlimited time duration (versus a 20-minute maximum in some other console versions). Cooperative games have a "Friendly fire" option that can be toggled on/off.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC game which were ported unchecked into this game, including areas on some levels where players may become inadvertently trapped, and a program bug that can allow a player character to become stuck partially inside solid objects when reloading saved games. No controller customizing allowed. The process of saving or loading a save-game file is unusually slow. No ability to independently scroll the Automap (the Automap display is always in "Follow mode"). Deathmatch games are confined to single maps (exit switches/portals are deactivated). Some enemy types are not in "fast" mode in games played at "Nightmare" skill. No "Gamma Correction" feature or equivalent (however the first-person view tends to be brighter than in some other console versions).

o Miscellaneous: Port by id Software and Bethesda Softworks. 36 map levels, all of which are found in PC Ultimate Doom. As with other PS3 titles, this game supports the "Trophies" system, which allows players to track various accomplishments in the game, for both themselves and other players of the game on PSN. In "split screen" mode, the individual player screens retain the aspect ratio of a full-sized screen; As such, the first-person views do not expand to fill all available space on the display device for 2- or 3-player games. In Cooperative-mode games, whenever one player acquires a key, the same key appears in the inventory of all other players. A player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. In the first 3 Episodes of the game, Phobos/Deimos/ Hell landscapes are used as the background for the tally screens between map levels, showing the player's progress through the various stages of each Episode (this art is omitted from some other non-computer Doom versions). Music tracks are remastered in 5.1 Surround Sound, and so sound marginally different than the equivalent tracks in the original PC game. Some sound effects in this game are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom releases, but later abandoned). The red plus-shaped symbol on health power-ups has been replaced in this version by a red-and-white pill symbol. No built-in cheat codes.

Notes: In both games, the Episode 3 Mission 7 map is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.

17. SONY PLAYSTATION 3 DOOM II ============================== o "Doom II" for Sony PlayStation 3 ("PS3") is bundled in the software packages "Doom 3: BFG Edition" and "Doom Classic Complete". These are available for purchase as a digital download from the PlayStation Store (an online service for various Sony consoles/devices). "Doom 3: BFG Edition" is also available in physical-disc form.

o "Doom II" for Sony PS3 includes 2 games/Episodes: "Hell on Earth" and "No Rest for the Living".

o A Sony PlayStation 3 ("PS3"), model CECHK01, equipped with one standard PS3 DualShock 3 Sixaxis wireless controller (model CECHZC2U), was used as the test system for the PS3 Doom II game described in this document. For testing split-screen multiplayer games, additional PS3 controllers were added to the system. For testing online multiplayer games, the console was connected through the PlayStation Network ("PSN") to an identical console.

o Pros: This PS3 title features a nearly direct copy of PC Doom II v1.9 (and so includes all of the original PC maps and monsters, and virtually all of the original art, textures, music, etc.), and also includes an additional and separate 9-map Episode, "No Rest for the Living". In general, PS3 Doom II has fewer changes or omissions than other console/handheld Doom II games. Graphics resolution for this game is higher than that of most other commercial Doom II games (including the original PC version), improving the sharpness and detail of sprites and textures at longer ranges. Supports split-screen Deathmatch and Cooperative gameplay for 2 to 4 players, and full-screen Deathmatch/Cooperative games over PlayStation Network ("PSN"). Very fast gameplay and screen-refresh rate in both single-player and same-console multiplayer games. Single-player games in progress may be saved at any point and restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.). Game supports 16 screen sizes (but does not allow the first-person view to be expanded to fill the entire screen). Games played at "Nightmare" skill include re-spawning monsters (a feature missing from some non-computer versions). Includes an "Always Run" option (player is always in Run mode), and an option to turn controller vibration on/off. Patches or updates to the product may become available via PlayStation Network. Game allows storage and management of a large number of save-game files (far more than other versions), and the displayed file information includes map name, Difficulty, play time, and a timestamp for the file itself. Weapons are cyclic-access (in 2 directions), and some may also be accessed directly by category type (bullet, pellet, energy, etc.) via the controller's D-pad. Deathmatch games may be set to an unlimited time duration (versus a 20-minute maximum in some other console versions). Cooperative games have a "Friendly fire" option that can be toggled on/off.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC game which were ported unchecked into this game, including areas on some levels where players may become inadvertently trapped, and a program bug that can allow a player character to become stuck partially inside solid objects when reloading saved games. No controller customizing allowed. The process of saving or loading a save-game file is unusually slow. No ability to independently scroll the Automap (the Automap display is always in "Follow mode"). Deathmatch games are confined to single maps (exit switches/portals are deactivated). Some enemy types are not in "fast" mode in games played at "Nightmare" skill. No "Gamma Correction" feature or equivalent (however the first-person view tends to be brighter than in some other console versions).

o Miscellaneous: Port by id Software, Nerve Software and Bethesda Softworks. 41 map levels, total, 32 of which are found in original PC Doom II: Hell on Earth. As with other Xbox Live titles, this game supports the "Achievements" system, which allows players to track various accomplishments in the game, for both themselves and other players of the game on Xbox Live. In "split screen" mode, the individual player screens retain the aspect ratio of a full-sized screen; As such, the first-person views do not expand to fill all available space on the display device for 2- or 3-player games. In Cooperative-mode games, whenever one player acquires a key, the same key appears in the inventory of all other players. A player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. Some sound effects in this game are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom releases, but later abandoned). The red plus-shaped symbol on health power-ups has been replaced in this version by a red-and-white pill symbol. This version of Doom II also has changes to the original/PC "Hell on Earth" secret levels, including the replacement of all "SS Officer" enemies with Zombiemen.

o PC Doom II (Doom 2: Hell on Earth) and PS3 Doom II "Hell on Earth" map level comparison:

                        | PS3 DOOM II "HELL ON

Notes: PS3 Doom II also includes a separate game/Episode titled "No Rest for the Living".

o PS3 Doom II "No Rest for the Living" map list:

Notes: The "No Rest for the Living" Episode did not originally appear in the PC version of Doom II. This Episode first appeared in Doom II for Xbox 360, then in Doom II games for PS3, and in some repackages/updates of the PC game. All editions of this Episode include the same 9 maps.

18. APPLE IOS DOOM CLASSIC ========================== o "iOS" is an operating system by Apple Incorporated for their mobile devices (iPhone, iPod touch, iPad, etc.). "Doom Classic" for Apple iOS (also called "Apple iOS Doom" or "iOS Doom" in this document) is a modified port of the 4-Episode PC game Ultimate Doom.

o A third-generation 32GB Apple iPod touch, model PC008LL, was used as the test device for the Apple iOS Doom game described in this document. For testing multiplayer games this device was connected wirelessly to a second, identical iPod touch.

o Pros: This game is a close copy of PC Ultimate Doom v1.9, and so includes all of the original PC maps and monsters, and virtually all of the original art, textures, music, etc. In general, this game has fewer changes or omissions than many other console/handheld Doom games. Multiplayer ability, allowing 2 to 4 players in Deathmatch and Cooperative games via short-range wireless connection. Extensive control customization allowed. Comparatively smooth, high-resolution graphics produced via dynamic antialiasing. The "pixelation" effect (a drop in graphics resolution seen in other Doom games as the player character approaches a surface or object) is notably reduced here. Very good gameplay and screen-refresh rate. A game in progress may be saved at any point (but only a single save-game slot is available) and then restored later to the same point. Saved games retain copious information (player location, health, weapon, ammo and armor status, live/dead status of all monsters on the map level, etc.). During a game in progress, weapons are direct-access (after a single tap on the touchscreen to bring up a weapons menu). Built-in ability to listen to alternative audio on the device (music files, etc.) when playing the game. In the status bar, current ammo levels and ammo limits are always shown for all weapons (in some console Doom games, only the currently selected weapon has an ammo level displayed). On the Automap screen, zooming and scrolling functions are very quick and responsive. Apple iOS Doom has the greatest number and variety of built-in cheat codes among all commercial Classic Doom/Doom II games.

o Cons: Some infrequently-encountered flaws exist in the original commercial PC Doom/Ultimate Doom game which were ported unchecked into this game, including areas on some map levels where players may become inadvertently trapped. No documentation, background story, or gameplay information is included with the download. Because the touchscreen itself is used as the control interface, some part of the first-person view is always obscured during active gameplay. Only one save-game slot is available, and this slot is automatically written to whenever a player moves between map levels, overwriting any manually-saved game. No ability to play in Automap mode (gameplay is always paused while the Automap screen is displayed). When running, the game may override the device's optional "Auto-Lock" and "Passcode Lock" settings (used for putting the device in a sleep/password-protected mode if it remains unattended for a specified amount of time).

o Miscellaneous: Port by John Carmack and the PrBoom project team. Available as a downloadable application (or "App") via Apple Inc.'s iTunes/App Store. 36 map levels, all of which are found in PC Ultimate Doom. Unlike most other commercial Doom games, a player may choose any map to start a new game on. This game keeps a running tally of certain player achievements on each map, including whether or not the player played that map, got a 100% Kills or Secrets score, and/or beat that map's Par Time. No "Nightmare" skill level. Automap screen provides more color-coded information than the original PC games, including specific color designation for key-locked doors, secret areas, and differentiation for object types when using Automap cheat codes. In this game, "blurred" objects are translucent and faded, but otherwise maintain their normal colors and surface features (in the PC games, "blurred" objects, when visible, are a translucent gray, with a flat, flowing/scrambled surface). A player can select the fist weapon at any time, whether or not a chain saw or Berserk Pack has been acquired. In the first 3 Episodes of the game, Phobos/Deimos/Hell landscapes are used as the background for the tally screens between map levels, showing the player's progress through the various stages of each Episode (this art is omitted from some other non-computer Doom versions). Some sound effects are "pitch shifted" at random, which adds some variety to game sounds (this is a feature found in the earliest PC Doom releases, but later abandoned). An option has been added to allow a player who is killed in single-player mode to restart the map with some additional ordnance. Unlike some other Doom games, a player cannot switch to any weapon in the inventory that has zero ammo.

o PC Ultimate Doom and Apple iOS Doom Classic map level comparison:

Notes: In both games, the Episode 3 Mission 7 map is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.

Notes: This table gives an overview of the Classic-game Episodes appearing in the retail Doom products referenced in this document. (For more information, see the relevant game sections and map-comparison tables in this document.) PC Doom (1993 release) has 3 Episodes of 9 maps each, for a total of 27 maps; PC Ultimate Doom includes those same 3 Episodes, plus a fourth 9-map Episode (Thy Flesh Consumed), for a total of 36 maps. Note that the "Ultimate Doom" column in this table refers only to the 9 maps of Episode 4. In the "Doom II" column above, "HOE" is "Hell on Earth" (the original 32-map Episode), and "NRFTL" is "No Rest for the Living" (a newer 9-map Episode). The "Original-Xbox Doom 3" games listed here are "Doom 3: Limited Collector's Edition" and "Doom 3: Resurrection of Evil". While Doom 64 for Nintendo 64 is considered a Classic Doom-type game, it has a unique mapset, and so is not included here. Doom 64's maps are not copied from, and do not appear in, any other retail Doom game/product.

Notes: Map equivalency is based on general map layouts, not map names. (Examples: The PS1 "HELL KEEP" map is not considered a match for the PC "HELL KEEP" map, as the two map layouts are completely different; And although the Jaguar game has no map named "FORTRESS OF MYSTERY", the Jaguar's "DIS" map layout does match that of the PC "FORTRESS OF MYSTERY" map.) The PC Doom/PC Ultimate Doom map in Episode 3 Mission 7 is referred to as "GATE TO LIMBO" in the tally screens, and "LIMBO" in the Automap.

Notes: Map equivalency is based on general map layouts, not map names. In PC Doom II, map 11 is referred to as "CIRCLE OF DEATH" in the tally screens, and "'O' OF DESTRUCTION!" in the Automap. In GBA Doom II, maps "INDUSTRIAL ZONE" and "THE CHASM" are each split into 2 separate maps (parts "A" and "B").

Notes: "PC DOOM GAMES" includes Doom 1, Ultimate Doom, Doom II, and Doom 95; "XBOX DOOM GAMES" refers only to Old/Original-Xbox Classic Doom games. The PS3, SNES and Xbox 360 games have no built-in cheats so are not included. The "sound mix" ("high-resolution mixing") code, the "mass kill" ("destroy all monsters") code, and the "quiet mode" ("monsters cannot detect quiet player") code in the PC-games category indicate PC games played with Doom 95. In PS1 and Saturn Doom, the add-ammo code only adds keys if they can be used. In 3DO Doom, a player cannot warp to another map level during a game in progress; However, a cheat code is available that allows a player to start new games on any map except map 24. In PS1 and Saturn Doom games, maps 55 through 59 cannot be warped to from any map. In Doom 64 a player may only warp to maps 1 through 27, or warp to any current map to restart on it. In GBA Doom a player can only warp to the next map from the current map, or warp 10 maps beyond the current map. In the Xbox games secret/bonus maps are not accessible via the Warp/exit-level code.
