Limbo or Purgatory is a Catholic belief that between Heaven and Hell there is a place for the lost and for those who were neither good nor bad. That is where the XBLA exclusive puzzle game Limbo takes you (maybe). You play a boy who awakes in a forest, begins walking around and discovers that this is no ordinary world. It is a world populated by dangerous creatures and traps and other children who don't take well to you being there.
