The evil Rowan is trying to break open the Durable But Not Impenetrable Barrier and release the ghosts! He's placed Paranormal Energy Devices all over the Mercado Building, and it's up to the Ghostbusters to find them and get them out before the Cataclysm begins and the building is completely HAUNTED. You have to keep your eye on the number of Ghost figures on the board–if too many start showing up, rooms will become haunted. If 6 rooms become haunted at the same time, you lose the game! Once all Ghostbuster Movers are outside of the house with all 8 Paranormal Energy Devices (before 6 rooms have been haunted), the players win! Four ways to play Basic Battle, Basic Battle with Rowan, Advanced Adventure and Advanced Adventure with Rowan. Work as a team for this exciting game of strategy and Ghostbusting!
