Based on the award-winning Betrayal at House on the Hill board game, Betrayal at Mystery Mansion is the mash-up fans have been clamoring for!

Play as Scooby-Doo, Shaggy, Velma, Daphne, or Fred as you explore the mansion and its grounds, finding clues, encountering strange occurrences, and maybe even catching sight of a monster! When you find enough clues to learn what's really going on, that's when the haunt starts, and one player will switch sides to play the role of the monster! Will you be able to stop them before they carry out their sinister plan?

Betrayal at Mystery Mansion contains 25 new haunts based on popular episodes and movies from the Scooby-Doo oeuvre, with different monsters, items, events, and locations each time you play.
