Activision announced Monday the release of Call of Duty: World at War Zombies, a new 3D action game for the iPhone and iPod touch. It costs $9.99 and is available for download from the App Store.

Call of Duty: World at War Zombies features the original zombie map “Nacht der Untoten” (“Night of the Undead”), in which you fight to survive an attack of walking ghouls inside a barricaded bunker.

The game supports up to four players via Wi-Fi and two players via Bluetooth. It also includes a full list of unique achievements, leaderboard support that lets you compare your skills to others online, and support for future downloadable content. (Internet play requires Wi-Fi, it’s not supported on cell networks at this time).

System requirements call for an iPhone or iPod touch (second generation) running iPhone OS 2.2.1 or later.
