Unlimited Ammo With M2 Machine Gun

message: When you get ammo for the M2 machine gun, get into
one of the tanks. Move toward the middle (you will drop
down slightly), and when it says "press spacebar to fire",
you can shoot as much as you want. DON'T get out because you
will automatically lose all M2 ammo you collected
