Jon St. John, the voice of Duke Nukem, is voicing Vasalius: Human Error, a first-person action RPG built for a real Nintendo 64.
According to the company’s press release, The Retro Room Games opened a Kickstarter pre-campaign aiming for $6,400 to manufacture physical N64 cartridges with battery-backed save memory. The full Kickstarter hasn’t gone live yet, and the release doesn’t say when it will.

The release says nothing requires an Expansion Pak: the game runs natively on a stock 4 MB N64, and its voice work runs directly on the console’s hardware.
The sci-fi horror game drops players into a town under a sinister extra-terrestrial infiltration. Any survivor could secretly be a disguised host.
First-person combat meets RPG stat progression across 3D levels filled with 2D sprite enemies and five weapons. Survivor choices and suspicion checks lead to multiple endings.
John Riggs, a YouTuber, is also a voice actor in the game. The pixel art is handcrafted, the game uses zero generative AI, and the original soundtrack is by Leberch, Alex-morgan, and Atlasaudio.
The game is in English, and the release lists three versions:
- Nintendo 64, on a physical cartridge in NTSC and PAL versions
- PC
- Digital ROM
Bobby Prince, who composed the soundtrack for Duke Nukem 3D, died in June at 81, and Tbreak covered his death at the time.
The release gives no price for the finished cartridge, so the $6,400 goal is the only figure so far.
