Listen up rejects! Grendyl needs you to go down into the Snakestack and retrieve the airflow cogitator — but something nasty is brewing down there, so watch your backs…

Explore the setting of Warhammer 40,000: Darktide as Inquisitor Grendyl dispatches you to the Snakestack, a lost region of Hive Tertium, to retrieve a lost archeotech cogitator. The ventilation systems of the Snakestack breathe life into Tertium, but the depths of the hive are packed with traitor forces of the Moebian 6th, cultists pledged to the plague god Nurgle, and strange lost sects of the Mechanicus.
