A Pennsylvania haunted house will add a new level of fear this Halloween season by urging thrill seekers to run through the attraction stark naked.

"Think you're brave? Experience The Unknown haunted house with ZERO protection!" The theme park Shocktober Fest said on its site.

The Halloween spectacle is inspired by the Discovery show "Naked and Afraid," in which strand two nude strangers are stranded on an island together.

"The Naked and Scared Challenge allows participants to go through the Unknown Haunted House Nude or Prude (either totally nude or with underwear). It takes place at the end of the night after all customers have gone through the attraction," the site stated.

All participants have to be at least 18 years old, and are required to sign a waiver before entering the bare attraction.

The brave haunted house-goers undress in a "semi-private preshow building," make their way through the attraction, and then exit into a fenced courtyard where they can re-clothe.

Shocktober Fest stressed that the nakedness should be purely for the fear factor, and had no sexuality behind it.

"Shocktoberfest has created this experience so their customers can explore a new level of fear. This is about fear and pushing oneself out of their comfort zone. This is not about sex. No sexual misconduct, inappropriate or disrespectful behavior will be tolerated.
*Please note there is an additional cleaning charge if we scare the p*ss out of you!" the site stated in their disclaimer.

It will cost $20 to streak through the unique haunted house.
