Hello, I am going to host a kind of Survival Games server, but in an AC style. To do this I would need two plugins. They are simple, I think. Here they are Disguise yourself as a Villager. Like mobdisguise but be able to be hit and killed. One you kill a villager, you are killed. This would make it just like AC multiplayer, villagers everywhere with disguised players to find and kill each other.
use disguisecraft, it should work for the villager thing ... and for the "once you kill a villager, you are killed" there should also be plugins, but I'm not sure ...
