Airsoft guns, it's still considered a weapon and it would suck against zombies because it won't go through the skin, let alone a skull so it would be impossible to kill them unless you wack them with the gun.
best: something belt fed and of large caliber. like a belt fed shotgun. either that or a detachable magazine fed shotgun.
worst: non lethal crap
i just met some amazing people, and now have access to almost any kind of weapon i want, in addition to my legal ones.
i'll be using a combo of my super awesome weapons and my normal legit weapons. legit would be like my mosin nagant (a rifle that does everything), semiauto akm, .22s, handguns, 20 ga shotgun, etc. awesome would be machine pistols, belt fed machine guns, grenades, grenade launchers, C4, napalm, assault rifles, and anti tank weapons (like the law or rpg)
Pretty sweet 12 gauge. Seemed to be having some feed issues though. It woud be a pretty good gun for defense of a camp, or some form of strong hold.
