That my friend, is the quandry that has confounded many a person. However, I can only think of one explanation that would sound realistic. The chopper carried numerous boxes of ammuntion, each filled with a plentiful amount of pre-loaded magazines. Does that satisfy you?
Great game. Love the graphics and animation. But I'm getting tired of all the comments about it needing a storyline or upgrades. Story? The chopper has crashed, with the player surviving. The crash obviously has attracted every single zombie in the area. Upgrades? Where would he find the time to build or upgrade anything. He's trying to survive a continuous onslaught of zombies. Unlike humans, zombies don't rest. Nuf said.
