Call of Duty: World at War was one of last year's best games. However, some of you out there were a little disappointed about another World War II game. Of course all of this stems off of the fact that we're all just a little spoiled after Infinty Ward's release of Modern Warfare and it's sequel this year. OK, so World at War wasn't everyone's cup of tea, but there was a certain game mode that had everyone praising developer Treyarch for...Nazi Zombies! The popular game mode that had you and your friends blasting wave after wave of the undead has now arrived on the iPhone and iPod Touch.
