A free mod for 7 Days To Die, by Mipastu.

This is a PvP Only mod that is only applicable at night. At night, everyone will have their damage dealt and be at the mercy of anyone who attacks them. If you are attacked, your player will take the damage. This mod is not intended for PvP in the daytime. In the daytime, you are free to attack and kill other players, but the damage will only be set to “1.”

This mod does not change any of the existing functionality of the game. The only thing it does is it changes the way the game is played.
