A manhunt is a type of game usually consisting of x numbers of players, with x-1 humans and 1 wolf.  The wolf may or may not have two kills at night, depending on the size of the game: double-kill games usually are on the large side (14p), where a normal single-kill game tends to hover around 8-9p.  The main principle of this setup is to rely solely on interrogation and catching a person in their lies, as opposed to relying on the results of any power roles to gain definite clues to a player's alignment.
