Call of Duty: Black Ops II: Zombies

Treyarch confirmed that the Zombies mode would return for Black Ops II with new game modes. This is the third Call of Duty game to feature a Zombies mode, following Call of Duty: World at War and Call of Duty: Black Ops, and the first to have game modes other than the traditional Survival mode. Treyarch also confirmed that Zombies would run on the game's multiplayer engine, allowing for a deeper community experience, along with new features. A new, 8 player co-op game called "Grief" is also supported, featuring 2 teams of 4 players competing to survive, unlike the previous games which only supported 4 player online co-op. As with the previous installments, each Zombies map contains "Easter eggs" side quests, which is used to progress the story. Another new mode, "Turned", is introduced with several downloadable content maps, in which one player attempts to survive three player-controlled zombies who must turn the other player into a zombie.
