- The level "Be Careful With That Axe" was inspired by the Friday the 13th movies, the level "Campy Crystal Lake" in the Suckin' Grits on Route 66 expansion pack for the 1997 PC video game Redneck Rampage, and the 1997 PC video game Blood.
- The level "The Other Mansion" was inspired by the PC video games The 7th Guest, released in 1993, and The 11th Hour, released in 1995; both games were developed by Trilobyte. The level contains references to Trilobyte founders Graeme Devine and Rob Landeros, as well as The 7th Guest and The 11th Hour music composer George Sanger.
- The level "Underground Fantasy Club 3000" is also known as "1024.map" because it uses all 1,024 sectors that a Build engine level allows.
- The level "Raccoon City" was inspired by the video games Resident Evil 2, released in 1998, and Resident Evil 3: Nemesis, released in 1999; both games were developed by Capcom.
