Have you ever wanted to star in a Horror Movie? DementedFX Haunted House may be the answer. Voted the number 1 haunted attraction in Massachusetts by's "Fan Poll," DementedFX features 20,000 sq ft of giant monsters, Hollywood quality props and sets, and hair-raising video/sound design that's sure to send you home with no voice, and possibly needing a new pair of jeans. The Haunted House features one cohesive storyline, "an immoral medical laboratory, ravaged by its own experiments, has let loose a virus that is turning the world into monsters and ghouls. You need to break into the lab and rescue the scientist who has the cure to save all humanity." The entirely indoor waiting area features two bars stocked with enough beer and wine to keep the party going from dusk till dawn.
