Sensory Overload

Intense fear-inducing experience

This intense fear-inducing experience will take guests to levels that 13th Floor has never gone before… Guests will enter a maze in complete darkness and need to rely on their sense of sound, smell, and touch to make their way through physical challenges. Disclaimer: Staff will not touch guests, however, this interactive experience will require that guests use their hands to guide their way, walk, duck, step over, and squeeze through some strange spaces.
