Black Ops 6 brought Zombies back to round-based maps after the open world of Modern Warfare III, and carried on the Dark Aether story of Black Ops Cold War. Its crew, Weaver, Grey, Carver and Maya, fights Project Janus and the rogue intelligence S.A.M. across six maps, from a prison island to the towers of Janus itself.
Terminus and Liberty Falls came out with the game, then Citadelle des Morts, The Tomb, Shattered Veil and Reckoning in the free seasonal updates. Every one of them has its First Room board here, from solo to four players.
