Downloadable content for Final Fantasy XV, an action role-playing game developed and published by Square Enix, was revealed prior to the game's release for the eighth generation of video game consoles in November 2016. It was mostly developed by a smaller team from the core Final Fantasy XV staff, supervised by director Hajime Tabata and headed by producer Haruyoshi Sawatari. Both free and paid downloadable content (DLC) were announced: among the DLC released were various promotional content utilised as tie-ins to the base game, such as A King's Tale: Final Fantasy XV as well as additional story elements intended to address player criticisms of the game's narrative structure and missing details. Three character-driven "Episodes" were released between March to December 2017, Episode Gladiolus, released on March 28, 2017, feature Gladiolus Amicitia as the player character along with an appearance by recurring franchise character Gilgamesh. Episode Prompto, released on June 27, 2017, takes place during a late-game narrative gap and follows Prompto Argentum as the player character, with the gameplay shifting towards third-person shooting and stealth-based mechanics. Episode Ignis, released on December 13, 2017, follows Ignis Scientia as he allies with the Imperial commander Ravus Nox Fleuret to protect Noctis. Episode Ignis was intended to be the final story-based DLC, though positive player feedback resulted in Square Enix wanting to develop further content focusing on other major characters such as Ardyn Izunia. A multiplayer DLC titled Comrades was released in November 2017, which is later superseded by a standalone version in December 2018. On March 6, 2018, an expanded version of Final Fantasy XV was released for PlayStation 4 and Xbox One as Royal Edition, and for Microsoft Windows as Windows Edition, which contains all pre-order and post-launch DLC published to that point in addition to further story and gameplay additions. Episode Ardyn, the final post-release content pack for Final Fantasy XV, was released in March 2019. Set thirty years prior to the main game, Episode Ardyn details how Ardyn was discovered by the Empire of Niflheim and began his plot of revenge against the Lucian bloodline. Other noteworthy DLC's included time-limited events like the Moogle Chocobo Carnival and Assassin's Festival, as well as crossover content with Final Fantasy XIV and Mistwalker's Terra Wars. (en)
