Activision has stated that further map packs will be released in the near future, free of charge, and Ascension was listed as coming soon in the map selection, while Call of the Dead's name was seen briefly after that. Dead Ops Arcade has also been fully transformed to the iOS platform, with 50 levels, and the player is able to select and play as one of the four characters from the console version (Tank Dempsey, Nikolai Belinski, Takeo Masaki and Doctor Edward Richtofen) or as one of the four random characters from Dead Ops Arcade and a 'rookie' soldier in the tutorial. The first map released was Kino Der Toten. The game allows two- to four-player co-op multiplayer, and, as a new addition to the iOS platform, voice chat, and another new feature - to crouch and full prone - a first for all iOS first-person shooters.
It is the sequel to the popular mode on Call of Duty: World at War, the fifth title in the Call of Duty series. Developed by Ideaworks Game Studio and published by Activision for the iOS and Android platforms, it was launched in select countries on December 1, 2011. Call of Duty: Black Ops – Zombies is a spin-off game of the Call of Duty series' Zombies mode and the sequel to Call of Duty: Zombies.
