Map pack 1 Zombies
When you have enough go up the stairs and get to the box tur nthe electricity on. Then once you have about 4500 buy some bouncing betties. Place one anywhere. Then place one near a perk-a-cola machine, if done correctly when you buy the perk you should have no weapons. Then go buy a weapon, or go to the mystery Box, you should have 3 weapons now. But this cannot be done at the end of the level. So when there is one zombie left blow his legs of with a grenade then do this cheat. This cheat is not the easiest to do so it may take a few tries.
