Call of Duty: World at War Tips

Nazi Zombie Survival
The first thing you should do is first gather enough points so you can open the door labeled "Help" then go and buy the Trench gun (Shotgun) this works good for multiple zombies coming after you the bullet will even go through a zombie and hit another. The only bad part about the shotgun is long reload times. Next,use molotovs to burn the zombies if close then buy the rifle "Bar" and prepare for fast firing but each level zombies get faster so make sure you move around while reloading.

Good Hunting!
