BFG room in PC Final Doom map 20, Central Processing (original) (raw)

How to get to, and escape from, the "BFG room" in PC Final Doom TNT level 20, Central Processing:

TO FIND THE BFG 9000

You start the level near the middle of the western half of the map, at the south end of a hallway. Walk north to an intersection, then turn right and proceed east to a metal door ahead.

Go through the door and turn left. Head north into an area dominated by metallic desks, chairs and partitions. In the middle of this area, on the other side of the main partition line, is a red teleport pad on the floor. Go to it and step on.

You'll materialize in a room to the south of the partition area. You'll be facing south towards a box. Walk south a few paces, passing to the left of that box. Up ahead and just to your left will be a line of boxes on the floor. The boxes run from a small box on the floor to a series or larger boxes to the west.

Walk up these boxes like a stairway. At the top of the "stairway", turn left to face the corner of a large box that's as high as the room itself. Activate this upper right panel of the box and it opens.

Step north into the box. You'll drop down a bit to floor level. Step directly ahead and Activate the north wall of this box from the inside, and it opens. Step through the opening and continue ahead (north) to the northeast corner of this room.

Here you'll see a squarish brick column in the corner of the room, stretching from floor to ceiling. Step up and Activate this column like a switch, and it drops, allowing you to get on and ride up when it ascends again a moment later.

At the top, look for an opening to the north. This opening leads to an area that is laid out in a rough "7"-like shape. The perimeter of this area has a corrosive floor; be careful not to touch it. Running along the center of the floor is a low trough; you can walk here without being burned. Step into the trough and turn right. Follow the trough a few paces east, then south to the BFG 9000.

TO ESCAPE FROM THE BFG ROOM

The BFG is perched at the top of a small pyramid. South of the pyramid is a room with a teleporter and a switch. The teleporter is in a box-like hole, recessed into the south wall of that room; Above the teleporter, on the back wall of the recessed box, is the switch. You'll need to get into that room in order to leave this area.

Between the BFG and that room is a window. The lower edge of this window is initially too far above the floor; you won't be able to simply step through. There are two main ways to get through the window into the room beyond.

The recommended way is to stand where the BFG is perched, and use your pistol to fire one bullet south, at the switch above the teleporter. The bullet impact will activate the switch. This lowers the window edge a bit, and also drops the teleporter down near floor level.

It is also possible to get through the window before it is fully opened, by using a simultaneous combination of Run plus Strafe to run south, up and across the pyramid. (This "strafe running" maneuver yields a speed slightly above that of plain running, but moves the player at an odd angle.)

If you get into this room before the switch is activated, you can be trapped there. In this case, you may still be able to activate the switch by using the double-barreled combat shotgun. This weapon's pellet spread can sometimes reach the switch if the player is standing far enough away, at the north end of the room.

Once the teleporter is lowered you can simply step onto it. You'll materialize at the south end of a room which is located just south of the room where the boxes were stacked in stair-step fashion.
