Recognized as one of the nation’s premier haunted attractions, 13th Floor is back with an entirely new lineup of terrifying experiences for 2026, including The Stitchworks: House of Reanimation, where a scientist known as The Pharmacist has taken his experiments far beyond the limits of humanity, creating grotesque creatures stitched together and rebuilt with brutal mechanical enhancements.
