It’s a perfect match. Betrayal at House on the Hill is a widely-loved hobby board game about exploring a haunted house. Instead of coming up with a new, mediocre licensed game for Scooby-Doo, it was combined with the best haunted house game out there.
Scooby-Doo! Betrayal at Mystery Mansion puts players in charge of Mystery Inc. as they explore a haunted house, laying out room tiles as they move around. About halfway through, one player discovers the haunt itself! It could be any one of fifty different bad guys! Each game is different, as each haunted house the players build is randomly generated. Get your flashlight, find those clues, and solve the mystery!
