Treyarch has confirmed that the Zombies mode will return for Black Ops II with its own campaign. Its predecessors were Call of Duty: World at War and Call of Duty: Black Ops. This is the third time for the Zombies mode to appear in a Call of Duty game, and the first time to have its own campaign along with the main story. Treyarch has also confirmed that Zombies will implement the multiplayer engine, allowing for a deeper community experience along with new gamemodes. This means that even more people can play zombies at the same time. Further information about Zombies is not yet known.
