Serial Killer

Role Description:

The Serial Killer is an independently aligned role that may kill someone each night and wins by being last man standing.


The Serial Killer's nightkill is often considered factional, since they are their own faction. This means If investigated by a Role Cop or Vanilla Cop, a Serial Killer with no additional abilities should view as "Vanilla". Also, Firearms Inspectors should not receive a positive result for Serial Killers, since, in terms of flavor, Serial Killers are considered to be using knives rather than guns. Because it's difficult to win as a Serial Killer, it's considered very common to give them extra abilities, which may include: Being investigation-immune (will be viewed as town-aligned if investigated), being Bulletproof (immunity to shots), having Strongman capability (nightkill cannot be blocked or protected against) or having Ninja capability (nightkill cannot be tracked or watched). A Serial Killer whose nightkill can specifically bypass Doctor protection is sometimes called an Arsonist. A Serial Killer who will immediately die if they ever do not perform a nightkill is sometimes called a Psycopath, though it varies whether this variant must simply attempt a nightkill every night or successfully perform a nightkill every night. In larger games, the typical Serial Killer win condition might be amended. Possible win condition variants include having to live until a certain day, having to live until X amount of players are left in the game, having to have fired X number of successful shots or having to have killed an X number of townies/mafia/power roles. Some hosts have also been known to include two Serial Killers, whose goal is to outlast the other.
