The Village is your mission: You will attempt to save it or destroy it.
One minute you're a Villager, defending your theoretical home with every fiber of your being. The next, you're a Werewolf, framing your friends and accusing them of wanting to destroy your village, when really it's you who's been infiltrating it all along.
The game proceeds in alternating night and day rounds. The villagers win if they kill both werewolves. The werewolves win if they kill enough villagers so that the numbers are even.
Each game becomes an epic phenomenon, designed to test your personal judgement and moral character.
