Call of Duty: World at War: Zombies is a First Person Shooter game that pits you, a rookie soldier, against hordes of Nazi zombies in a war torn German bunker in World War II. That's right, you're fighting dead Nazis, turned into zombies. If you've played the zombie bonus mode on Call of Duty: World at War on a console game system, you'll know what to expect here: plenty of scary, creepy zombies, with WWII era rifles, shotguns, grenades, and flamethrowers.
