OPERATION DEADBOLT: AN ALL-NEW OPEN-WORLD ZOMBIES EXPERIENCE\n\n For the first time, team up with other squads to survive and fight massive hordes of the undead in the largest Call of Duty Zombies map ever. Zombie hordes have taken over the Exclusion Zone, but they're not alone.
Worry not about PVP: There is a maximum of 24 players in each server, but Modern Warfare Zombies (MWZ) is a PVE-focused game mode within Call of Duty: Modern Warfare III. Work together or ignore other players entirely.
