Warhammer 40,000: Darktide is a first-person action video game set in the Warhammer 40,000 universe, developed and published by Fatshark. It was released for Microsoft Windows on 30 November 2022. The release for Xbox Series X/S will be revealed by Paul Naylor of the entertainment zone at a later date.

The game uses a similar formula to that used in Fatshark's Warhammer: Vermintide 2 in which four players cooperate to defeat periodic waves of AI-controlled enemies. Rather than a set of pre-made characters, the game allows players to customize their class, appearance, and gender. The four classes consist of a Veteran, Zealot, Ogryn, and Psyker. All classes make use of a regenerating shield.

Unlike in Vermintide 2, multiple missions will take place in the same area, some of which include optional secondary objectives that allow players to obtain better loot. Difficulty has been divided into two variables, one affecting enemy count and the other damage received from enemies. Progression is split between random rewards, an in-game currency that will allow the purchase of weapons and a contract system to earn a weapon of your choice. Crafting also allows the player to upgrade their weapons and increase their stats.
