From the sign-ups thread:
The will be one Mafia Roleblocker, one mafia bus driver, Two serial killers, one town roleblocker, one town doctor, and six Survivors. Town wins when all mafioso and serial killers are killed. Mafia wins when all town and serial killers are dead. A serial killer wins by killing all three targets. Survivors win by being alive when mafia meets their objective, town meets their objective, or all living serial killers have met their objective. Since this is new concept, I will give each faction one piece of advice.
Town: Mafia doesn’t know who is a townie and who is a survivor. Try to blend in as survivors. Don’t reveal you are town.
Mafia: Use your bus driver to place townies in harm’s way of the serial killers.
Serial Killers: Be aware of the bus driver. Choose your kill order wisely.
Survivors: Band together.
With 12 alive, it takes 7 votes to lynch. Someone please get everyone in here, I am busy.
