Modern Warfare Zombies continues the story set up in 2021's Call of Duty: Black Ops Cold War. With Cold War's Outbreak mode, players got the first taste of an open-world, objective-focused zombie experience. Expanding the open world concept into the gigantic mission area of Urzikstan, Modern Warfare Zombies provides a massive, 24-player co-op Zombies mode that furthers the story of Officer Weaver and Captain Ravenov as players work alongside Ravenov and Task Force 141 member John 'Soap' MacTavish in a mission known as Operation Deadbolt.
