Recently, Activision and Vivendi released a Call of Duty first person shooting game for the iPhone and iPod Touch. Though this is not like its console game predecessors, it's still a nice game and a great addition to the App Store. The full title of the game is Call of Duty: World at War: Zombies, which is pretty much self-explanatory for the core gameplay – as the title suggests, it is a zombie survival minigame. The game currently only has one map, with more to come in future updates via DLC. Is this game really worth the steep $9.99 price tag?
