If “the experiment went wrong” is your favorite genre, MANDELBROT SET is going to feel like a warm, irradiated hug. This campaign kit for FIST: Ultra Edition drops your paranormal mercs into rural Nevada, where a military Transdimensional Resonator has turned reality into an overlapping collage of broken timelines, impossible landscapes, and very bad days. The Fractal Zone isn’t just dangerous—it’s shifting dangerous. Your mission: breach the Zone, find Dr. Okonkwo, and shut down the Resonator before the Army “fixes” everything in the worst way possible.

Built with a looping, roguelike mission structure, MANDELBROT SET lets you revisit the Zone again and again while it never quite looks the same twice. You’ll hex-crawl through eerie outposts, infiltrate the nightmare guts of Facility Zero, bargain and brawl with aliens, gods, and unlucky survivors, and maybe rescue a version of Dr. Okonkwo who isn’t from your timeline at all. Packed with maps, locations, enemies, traits, items, and referee tools, it’s a multiversal toolkit you can mine for countless FIST operations—full campaign, one-shots, or “weird Cold War side mission” nights.

If you like Half-Life, Roadside Picnic, and Cold War disaster stories where physics and metaphysics both give up, this is absolutely your flavor of trouble.
