At the beginning of the game, it is unknown who the slasher is. The person whose turn it is plays a 'scene' card. This may allow movement, may allow an attack, may be a clue to the slasher's identity. After the scene card is played, each player gets a chance to play a 'plot twist' on the scene.In the course of the game, the first person to get three clues becomes the Slasher, and the dynamics change a bit.The game continues until either the Slasher is dead or all player victims are dead.Hilariously fun social game. - BoardGameGeek
