Towards the Idea of nonlethal weapons, i love the idea. But Rubber bullets are really rare in real life. Such things as Tear Gas Grenades and Stuff that disables would work. *Tear Gas Grenades (Knocks any player in it for to long out) *Stun Gun (Secondary) *Mace(Bottle) *Flash Bangs Grenades (Your vision burrs alot and your aim is everywhere for a few minutes) *Concision Grenade (Your character passes out for a minute)
Your idea is a great End Game idea. Hope the Devs listen to the idea. As the game is, there is no point of playing in the long run. Your idea turns it in to a tower defenses, for both Zeds and Players.
A Zombie is a living being (Except for the brain). If your hit with a .45 Round in real life, your going to die... fast. I this the gun damage is fine as it is. Same for players. A shot or to and your dead.
