A game where 1 person is chosen randomly to be the traitor and all the other innocents try to kill him, but only the traitor knows who the traitor is(you know himself).
The traitor will get a diamond sword and a iron one, the innocent gets a iron sword.
TIP: it will still say who killed who you just gotta pretend you killed the guy because you thought he was the triator(if your the traitor :P).
