Microsoft announced several game updates, in-game items, and new titles in development to mark the 25th anniversary of the original Xbox console, according to an Xbox Wire post on Thursday.

The announcements include new game modes, the addition of classic Xbox games to PC, and confirmation of upcoming titles. The company said 25 original Xbox games, including Star Wars: Knights of the Old Republic and The Elder Scrolls III: Morrowind, are now available on PC through Xbox Backward Compatibility. Achievements were also added to select original games.

For existing titles, a cooperative survival mode called Firefight will arrive in Halo: Campaign Evolved as part of a free Winter Update. DOOM: The Dark Ages will add Slaughter Mode on Nov. 16 at no additional cost for owners of the Revelations DLC, the Premium Edition, or the Premium Upgrade. The mode features escalating rounds of randomized enemies and bosses.

Xbox CEO Asha Sharma confirmed that Wolfenstein 3 is in production at MachineGames, with actors Brian Bloom and Debra Wilson reprising their roles. Sharma also announced that id Software’s next project is in development.

New gameplay from Fable was shown, featuring magical combat and story clues.
