"You're the best brother ever!"
About
A group of middle school alumni meet at a campsite for a reunion, but they are kidnapped by mysterious people and forced into a deadly Mafia game. While it seems like a normal game, it is a real [killing] game. During the day, participants spend time talking or voting. The Police and Doctor can only act at night on even-numbered days (2, 4, 6, 8). The Mafia enters the target's room at night to shoot them. Ordinary citizens, as well as the Police and Doctor on odd-numbered days, must stay in their rooms at night. (One can secretly move to another room; while people rarely leave at night, it seems they aren't eliminated unless caught by the Mafia.) It is extremely dark at night. You die if you are eliminated by vote (5-minute voting period) or if you are targeted by the Mafia. The Mafia must kill their target within the time limit (5 minutes), or they themselves are eliminated. If the Doctor places a cross on a door, the owner of that room cannot be killed by the Mafia that night. The Mafia members have radios to communicate at night and know each other's identities. During the night, one of the two Mafia members kills another survivor. If all Mafia members are eliminated by vote, the citizens win. If the two Mafia members kill all citizens, the Mafia wins. The Mafia can only kill one person per night. Roles cannot be changed once assigned.
