This might be the last « active » server on Zombie Panic! (Half-Life 1 Mod) dedicated to delivering the ultimate GoldSrc zombie experience, exclusively during organized events on our Discord server.
Since this mod is a bit unstable, we are focusing on stabilizing it, fixing and adding good maps. And yes, we know having bots would be good.
