Well, I rolled as a Vigilante and I managed to get the Serial Killer to team up with me, by pulling a bluff. He thought I was the Mafia the whole game and I had him take down the Arsonist and the Mafioso.
Probably my favorite and best moment I've ever had. We, the town, ended up winning in the end, thanks to a Sheriff.
My only regret that game, was that I made an ass of myself.
