For Call of Duty: Black Ops 4, developer Treyarch is leaning hard into Zombies, the cooperative multiplayer mode that the studio is famous for creating. Black Ops 4 will launch with three separate Zombies modes, including a re-imagining of the Mob of the Dead map known as Blood of the Dead.

Blood of the Dead will send Black Ops 4 players back to Alcatraz, where they’ll play as Edward Richtofen, “Tank” Dempsey, Takeo Masaki and Nikolai Belinski as they explore a secret laboratory beneath the island prison.
