The Map Pack was supposed to include three Zombies maps, all of them teased in the last World at War map Der Riese. However, due to the reallocation of ressources at Treyarch to complete the Call of Duty: Black Ops campaign in time and the fact that it would have been released too close to Call of Duty: Modern Warfare 2; the Map Pack was ultimately cut.[1]
The maps were used in Black Ops Zombies mode with the Theater map becoming Kino Der Toten, the Coast map becoming Call of the Dead and the Paris map becoming Moon.[2][3]
