@FaceBreaker that is a good srtatagy, but i think mine is better. Upgrade your zombie exp to the highest, then cash, then health regeneration ( only up to 2nd), then up grade accuracy and reloading.
P.S u can upgrade accuracy and Reloading speed anytime u want to.
Weapon Order
Get revolver, The Winchester, Skip the Uzi, Mossberg, skip AK, M16, then buy chain gun
Hope this helps
