What To Expect
As you walk through the gates of DementedFX and you’re no longer just a spectator—you become the lead in your own horror film. This immersive experience is a total sensory takeover, featuring cinematic set design, bone-chilling sound, interactive video moments, and towering monstrous creatures that blur the line between fantasy and fear. Your journey begins in an indoor, apocalyptic immersive theater where you'll encounter the leaders of "The Resistance," a gang with their own dark agenda. From there, you'll set on a mission into the heart of the renowned BioMedCorp haunted house.
Inside this post-apocalyptic wasteland, your mission is to infiltrate a lab ravaged by a monstrous virus, face the horrors within, and rescue the one scientist who holds the cure. The choices you make—defy the resistance or ally with them—weigh on the fate of this dystopian realm. For those craving an even more intense experience, a VIP Lounge and two fully stocked bars are ready to fuel the night. This theatrical horror odyssey is where each twist leaves your heart pounding. Dare to play your part!
