Any number of players can move in the same map and shoot at each other until they die; they can shoot at zombies too; they can collect rotten meat in their inventory. Meanwhile they must keep fed and hydrated.
I tested in a LAN, but it should work in any network. You can even start multiple clients locally if you don't have other people. Let me know how many people you manage to handle!
I will keep adding stuff to this game and will keep you updated.
Make any question down here!
