Mystery Flesh Pit National Park the RPG

Rate this book
Cosmic Horror Meets Bureaucratic Satire

For years, artist Trevor Roberts has meticulously archived a fictional alternate timeline at MysteryFleshPitNationalPark dot com, when a oilmen accidentally drills into a cosmic horror beneath the dusty plains of west Texas.

Over the decades, the Permian Basin Superorgamisim goes from roadside attraction to National Park and natural resource, all documented through tourism signage, "wildlife" brochures, safety manuals, and government memos. When we saw this magnificent online grotesquerie, we knew this would be an awesome tabletop RPG!

You can be a Charming Person in Black who Operates Undercover or a Pit-Touched Park Guide Who Runs Away. Odds are you will be fighting off Conformity or find yourself filling out incident reports while the screaming is coming closer. Just keep in mind the Prototypes from R&D are a mixed blessing at best. Embrace being a Park Employee, Subcontractor, or keep your head down if you find yourself classified as a Special Contingency.

Compatible with the Cypher System, this standalone game easily supports GM improvisation and PC mayhem! Get your copy today!

It all began with half a rotting cantaloupe.

Illustrator Trevor Roberts was employed by a small architectural firm when he entered the office break room one day in the summer of 2019 to find the wilted remnants of a co-worker’s breakfast lying atop the counter. This inspired him to go on a worldbuilding subreddit as a creative exercise with digital-name of Strange-Vehicles, and change his life forever.

Seeing the centlope, he took stock photo of an open pit mine in South Africa and Photoshopped the open cantaloupe into it, turning it red and meaty. With Covid the idea snowballed into what it is today.


Mystery Flesh Pit National Park is a giant grotesque maw of an indescribably ancient subterranean colossus (referred to as the “Permian Basin Superorganism”) that is hundreds of miles long . Texas being what it is, it was turned into a lucrative tourist attraction sanctioned by the American government... until 2007, that is, when Anodyne's lethal negligence causes a horrific tragedy.

The park started as a series of guides and brochures that operated for several decades before an unforeseen disaster shut the place down over July Fourth weekend in 2007 along with its own timeline.

4/5, Haven't played the rpg but the setup is suitable. Plus it's nice to see a web original artist kick-off and create something big. All this stuff would make for one hell of a movie or TV show, apparently several streaming services have shown interest.
Suitably horrific.

Im giving this 3.5 stars. I am familiar with the website so when I saw this rpg version I was expecting a greatly expanded “world” and more information about what the pit is.
If you take away the crunch and adventures there isn’t a ton of stuff we don’t actually know apart from creatures, and I feel like some of the best parts of the website were even left out of this.

I’d recommend reading this even if you aren’t going to play the game because it has so much new information on the park! I’ve being following the mystery flesh pit story since I was in middle school and I really hope more stuff is released in the future!
