Call of Duty: World at War game developer Treyarch and publisher Activision have announced a new iPhone game, based on the Zombies gameplay mode from COD: WaW, is now available.

Details from Activision:
“Call of Duty: World at War: ZOMBIES offers both single player and the game’s highly-addictive co-op gameplay experience in full 3-D, allowing up to four players to join a game via Wi-Fi, locally or across the Internet, and up to two players via Bluetooth, all on the go!”

You can look foward to new maps as time goes on.
