Guys IF UR having trouble with winning lvls on here like u keep trying to find weapons and all u get is a revolver or ump... well i got a solution. find survivers and repair ur bunker about 25% unless it is 75%. then when ur fighting if zombies come up to ur base like a lot of them, then the secret is go 2 the top of ur base and shoot ur way down, cus i tried the opposite way and i got pwned by zombies. + up if this helps u or if u think there should be a last stand three.
