Roberts has taken world-building to a new level with the Mystery Flesh Pit National Park project. He has created a rich and detailed world that is both absurd and terrifying. The world of Mystery Flesh Pit National Park is a grotesque and macabre place, filled with horrifying creatures and bizarre natural phenomena.

It is a place where the laws of nature are twisted and distorted, and where the very earth itself seems to be alive and hostile.

The park is described as a “bizarre natural geobiological feature” that was discovered in the Permian Basin region of West Texas in the early 1970s. The pit is characterized as an enormous subterranean organism of indeterminate size and origin embedded deep within the earth, displaying a vast array of highly unusual and often disturbing phenomena within its vast internal anatomy.

The surface orifice of the Mystery Flesh Pit was enlarged and internal sections were slowly reinforced and developed by the Anodyne Deep Earth Mining corporation, who opened the pit as a tourist attraction in 1976. In the early 1980s, the site was absorbed into the National Park System, which operated and maintained the Mystery Flesh Pit until its sudden closure in 2007.

Roberts tried a Kickstarter video game, but failed fast back in November 2022 stating, “Most people do not fully appreciate what a substantial undertaking it is to produce even a modest video game.”
