Mafia

Welcome to the truly insane side of the town! As you are completely mad anyway, you cannot be insane in the traditional sense.

Once per night round, you may choose to conduct surgery on either a "red townie" or a "green townie". Once you do so, they will be given a number (but you won't know who they are) and transform into whichever role they would have transformed into anyway if they were at the top of the list. You will receive +2 points for doing this, meaning that you only have to conduct surgery on 5 people in order to win the game.

Once per night round, you may also choose to turn one of the people you have converted insane. Of course, you don't know if they're insane already, but a little extra insanity couldn't hurt, could it?
