Call of Duty: Black Ops Rezurrection - Zombie Lab Phase 2

Call of Duty: Black Ops - Rezurrection is a DLC expansion requiring the base game, focusing entirely on enhancing the cooperative Zombies survival mode. Released in 2011, this package adds five maps: four remastered classics (Nacht der Untoten, Verrückt, Shi No Numa, Der Riese) and one new environment, Moon, which takes players to Area 51 and the lunar surface. The core loop involves wave-based defense against the undead using established mechanics, offering substantial new arenas for veteran players without introducing new systems.
