Call of Duty: Black Ops Zombies is a spin-off game from the Call of Duty series zombie mode and the Call of Duty: Zombies sequel.

The game allows cooperative multiplayer for two to four players and adds voice chat and another new feature - crouch and prone - a first for any iOS first-person shooter.

The game features 50 levels, and players can choose from the console versions (Tank Dempsey, Nikolai Belinski, Takeo Masaki, and Doctor Edward Richtofen) and play as one of four characters or as one of four random characters in Dead Ops Arcade Activision has said it will release more map packs for free in the near future, and soon listed Ascension in the map selection, and shortly thereafter saw the names of the dead. Both maps have been released.

The first map released was Kino Der Toten. 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. 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. Both of these maps have been released.

Kino Der Toten is much like its console/PC counterparts with the exception that its central stairway has been changed to two ramps that go in two directions and meet back up. All doors, perks, and weapons cost the same number of points as on console/PC.

"Ascension" is also quite similar to its original gameplay with the return of space monkeys, the pack a punch process, perks, and guns.

Option to use the game's CoD point system to enhance the experience and get out of trouble.

With six tiers of in-app purchase options to choose from, Zombie Fan can take your experience to a whole new level by unlocking more areas and acquiring better weapons in less time. Please note that CoD points are only available for single-player games.

Purchase CoD points in the Main Menu to use when you run out of points in the game.

CoD points can be used for any item in the game, such as resurrection, door opening, weapons, perks. and mystery boxes, but only if you do not have enough points.

If you die without a respawn perk, you can also buy respawns with CoD points, although the three respawn limit still applies.

The various weapons and perks are available to mow down hordes of zombies when playing solo over Wi-Fi or joining a team of up to four players.
