stay with the first gun until u get the SMG, then get upgrade scavengers and aids, it helps ALOT! get assistant and upgrade him to the first sub machine gun, after that up the strength of the smg and don't buy ak47 or any other weapon just hold on till you get the minigun, then it's over :) get assistant and upgrade him to the first sub machine gun
