final girls are almost always very different characters from the rest it doesnt make sense that there is no mechanic for this the final girl is an important component of the slasher flick, second only to the killer himself

therefore, before the beginning of a new story, make a roll to determine who will be the final girl/guy, which we will call The Survivor

The Survivor gets unlimited genre points they can still die but they have very real advantage

the survivor wil be the one character who benefits from making wise decisions

this mechanic also prevents everyone from trying to be the final girl encourages leading characters to the slaughter - they know there's almost no hope of surviving.
