This Garrys Mod Addon is simple. if you play TTT with the new roles addon then one of the traitor roles is the Zombie and this helps with a House rule we have
On our server we have a house rule that the zombie is not allowed to shoot players they have to use their claws to kill.
This addon enforces that by killing the player if they use a weapon and hit a player with it that isn’t either their claws or crowbar
