iPhone infested with Call of Duty: World at War: Zombies II

The war against the undead Nazis rages on with the release of Call of Duty: World at War: Zombies II for iPhone and iPod touch.

Following up on the hit original, this new iteration offers a new map, weapon, and playable characters. The map, entitled Shi No Numa, is set in a dank swamp infested with Nazi zombies (of course).

Along with the new map, you can equip the Wunderwaffe DG capable of frying enemies. Also offered are new equipment like the zipline for quick escapes.

The game isn't so much a sequel as it is a standalone expansion pack for the first instalment. In fact, the Shi No Numa map can be downloaded from within the original Call of Duty: World at War: Zombies.

If you opt for the download, it's not as expensive as the full game; however, it's still pricey at $4.99/£2.99.

Call of Duty: World at War: Zombies II is available for iPhone and iPod touch at a price of $9.99/£5.99.
