Id Software is adding Slaughter Mode, a horde-style endless survival challenge, to DOOM: The Dark Ages next week. The new mode is scheduled to release on Monday, November 16, 2026 and is described as testing even experienced players with randomized enemy encounters, bosses, and arenas.
Sources also say Slaughter Mode will include systems for recording personal high scores and taking part in weekly challenges. Access is linked to ownership of this year’s Revelations expansion: while the update is positioned as free, it is available to DLC owners and requires Revelations to play. Across outlets, the main emphasis is on the release timing and the mode’s replayable “endless survival” structure rather than on broader gameplay changes.
Xbox’s official news entry frames the announcement around the date and the update arriving for DOOM: The Dark Ages | Revelations, while Pushsquare provides additional detail about the mode’s features and access requirement.
