Call of Duty: World at War: ZOMBIES is available on the App Store for the iPhone and iPod Touch. Okay, it costs a monumental £5.99 but "this mobile version of the hit gameplay mode from Treyarch's blockbuster title Call of Duty: World at War" provides both single player and co-op gameplay experience in "full 3-D". Play via Wi-Fi, locally or across the Internet, and up to two players via Bluetooth.
Hold on, "Full-3D"? Could that possibly be just a smallish over-statement of the actual facts? Yes it could. Anyway, we'll have a look.
