Call of Duty: Black Ops Zombies, adapted from the console hit and built specifically for tablets and smartphones, features the Kino der Toten map and 50 levels of Dead-Ops Arcade.

Play solo or join a team of up to 4 players as you mow down hordes of zombies and chat to friends thanks to all-new Voice Chat.

Dead Ops Arcade mode is unlocked by finding the four missing coins in the game's menus. Once enabled, you'll have access to a 50-level zombie gauntlet with full Game Center leaderboard support.

Call of Duty: Black Ops Zombies is priced £4.99 and is optimised for third-generation devices. Expect ongoing upgrades to the game, new features, maps and special surprises, says Activision.
