You'll have to sign a 40-page waiver, create a safe word, and get a full physical before the horror experience even begins.

A haunted house in Tennessee is so extreme participants must sign a 40-page waiver, create a safe word, pass a drug test and more before entering.

But a lucky survivor of the tour will be handed $20,000.

McKamey Manor, however, is so terrifying, no one has ever finished, according to WFLA.

A website ad touts McKamey Manor as "The world's only TRUE interactive 4 to 7 hour extreme haunt experience." Owner Russ McKamey said he has spent over $1 million creating a haunted house where fans can live out their horror flick fantasies for free -- just bring a bag of dog food for one of McKamey's five dogs.

"Which is crazy. I'm not a very good business person," Russ admitted to the outlet.

In clips featured online, participants -- who appear bruised, bloodied and utterly petrified -- are pushed around, blindfolded, screamed at and buried in mud. Plus some have their hair shaved off. Just your average Halloween family fun.

To tap out, they must utter "You really don't want to do this" into the camera.

Before guests begin their harrowing journey, however, Russ requires them to watch a two-hour movie. The video -- "And Then There Were None" -- is basically a torture porn montage of every contestant who tried to survive the ordeal between July 2017 and August 2019.

Here is a full list of the other requirements:

Be 21 years old or older, or 18-20 with parental approval

Completed "Sports Physical" and doctor's letter stating you are physically and mentally cleared

Pass a background check provided by McKamey Manor

Be screened via Facebook, Facetime or phone

Proof of medical insurance

Sign a detailed 40-page waiver

Pass a portable drug test on the day of the show

But how does Russ conjure up enough fear for fans to call it quits before grabbing the cash prize?

"When I use the hypnosis I can put you in a kitty pool with a couple inches of water and tell you there's a great white shark in there, and you're gonna think there's a shark in there," he explained. "And so, when you have that kind of power over people, and have them do and see things that you want them to see, then they can leave here thinking it really happened."

And we thought Jigsaw was twisted.
