[STATIC]—is Dr. Onyemaechi Okonkwo, calling from—from Nevada, our Nevada, from our world, where the Allies won the war, where there’s no hole in the Moon, where Ancient Rome fell—please, if you can hear me, we need help. My coworkers and I—there are seven of us left alive—we were caught in an accident. The Transdimensional Resonator—my God, how could we have ever known it’d end up like this—[STATIC WORSENS]

MANDELBROT SET is a campaign kit for FIST: Ultra Edition inspired by Half-Life and Roadside Picnic. Scientific disaster strikes when a military experiment transcends control and breaches the boundaries of our dimension, turning a sizable area of rural Nevada into an abstract amalgam of parallel realities overnight. According to the desperate mayday transmitted from within, the players have three objectives: infiltrate the FRACTAL ZONE, rescue DR. OKONKWO from the volatile facility at its center, and neutralize the TRANSDIMENSIONAL RESONATOR before the Army makes matters worse in its own attempt to control the fallout.

This campaign kit features a roguelike looping mission structure and enough content to keep each turn around the Wyrd fresh—with over sixty pages of maps, locations, enemies, traits, items, and referee guidance, your group can assemble its own unforgettable version of MANDELBROT SET over and over again. This book is designed with broad utility in mind, leveraging the multiverse as a vehicle to present a wide array of statblocks and situations you can cut to size for your own FIST campaigns.

• PERILOUS HEXCRAWLING: Roll from a table of thirty-six detailed outposts, from haunted Spanish missions to Atlantean tactical relay points, to construct a new version of the Fractal Zone for each mission. Consult the Corruption Meter as you navigate the fickle locale and its transient denizens.

• THRILLING INFILTRATION: Breach Facility Zero and explore an ever-shifting menagerie of opportunities and obstacles, including the convenient mercenary automat and the abominable Dr. Phalange. Face transdimensional terrors in the halls, and fight multiversal chimeras in the Resonator Room.

• COLORFUL CHARACTERS: Tangle with aliens, gods, and vengeful castaways in the Wyrd, then rescue six survivors from the facility: sly scientists, trigger-happy soldiers, and a particularly unlucky janitor. Your primary target is Dr. Okonkwo, who may have been replaced by a post-apocalyptic wizard or modern-day Roman by the time you get there.

• MAGNIFICENT MECHANICS: Fall victim to thirty-six new fractal traits, outlandish powers which only exist inside the Zone, and track down thirty-six collectibles, unique anomalous artifacts with special effects. Negotiate the fifth dimension, lose comrades in strange loops, and find yourself changed forever.
