Nice. So...may I recommend upgrades? (sabot rounds, silencer, scope, etc.)
Actually I considered a scoped weapon at one point, similar to the rifleman's scope in gg2, but I haven't bothered to figure out how to get that to work. The silencer would be nice, though I'll save that one for when I fix up the zombie ai.
So yea, recommend what ever you want.
Laser sight that stops at where it hits a wall instead of being cosmetic
Scope (I will help you later if needed)
Drum magazine (Uzi and Shotgun only)
Bipod (When standing still accuracy is increased greatly)
Grip (Weaker Bipod but works when moving)
