Arx Mortis. Killen, Alabama: Certainly, the location alone gets this haunted attraction a few scare points. This is a 50,000 square ft scare park that features both a haunted trail and a detailed recreation of a 1940’s sanitorium. Both animatronics and live actors give jump scares, and although there’s 23 “Leave Early” escape doors, they don’t offer refunds for bailing.
