Few places are truly safe from the demons and their horrid plague. Rumors spread amongst survivors of a maximum security prison that has become a fortress for humanity, though the denizens may be more frightening than the horde. "Rehabilitation" follows the players' flight from their shelter in an old sporting-goods store as they attempt to find a safe haven and cure to the plague.

This guide aids game masters in directing a Catalyst campaign. "Rehabilitation" takes 3-5 players through a short, 3-session campaign.
