Laws of the Night is the Live Action Role Playing (LARP) game based on White Wolf's Vampire: The Masquerade.
It is set in the same gothic-punk World of Darkness that its parent RPGs are set.
The game is a derivative of the Storyteller system and has been streamlined to be able to resolve conflicts very quickly by using a Rock, Paper Scissors mini-game. The outcome of the mini-game is modified by the characters skills and abilities.
Laws of the Night is a complete re-write of the original LARP, The Masquerade.
