Call of Duty: World at War: Zombies is the Nazi Zombie mode on the Apple iPod Touch/iPhone™, which is available for purchase for exactly $4.99 (previously $9.99). It includes the maps Nacht Der Untoten, Verruckt, Shi No Numa and Der Riese. It is unknown if the new Black Ops maps, Kino der Toten, Five,and the DLCs, will be released for this app.
There are several notable differences in the iPod version, namely the lack of recoil on most guns. Some weapons, such as the Ray Gun, are unusually weaker, and slight differences in their shooting is noticeable. The Ray Gun specifically is severely underpowered, losing it's one-hit kill ability at about round 16. It becomes a two-hit kill until around round 21. Although these changes have being made from the original Nazi Zombies, you can still play online via Wi-Fi, or Bluetooth™. This is also free, so you can play online with people anywhere, or go with Bluetooth for matches with people who are around you who also own the game.
There are also a list of achievements, such as Pyromaniac, which give you a gamerscore of sorts. There are "Overall" achievements, for all maps, and others made for a specific map. Ther are currently 59 Overall achievements.
- The app is generally considered non-canonical, as it shows Dr. Richtofen being zombified in the tutorial.
