Turns out that's not the only media property being gamified in multiple ways this year as the recently announced game Scooby-Doo: Escape from the Haunted Mansion from The OP will have to share shelf space in game stores with Betrayal at Mystery Mansion, a game from Avalon Hill and Rob Daviau, Banana Chan, Noah Cohen, and Brian Neff that will debut on May 15, 2020 — the same day that the Warner Brothers movie SCOOB! will open in theaters.
As for what's in the game, here's an overview:
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.
