From the publisher's website:
2 players, 20-60 minutes, intense horror.
Can you escape from the murderous ghosts?
(Hint: probably not.)
Play your book and your wits against the GM’s book and her twisted, murderous, bloody imagination.
Murderous Ghosts is a self-contained 2-player RPG by Vincent Baker. The game consists of a "Player Book" and an "MC Book", with an inter-dependent structure which directs play.
