From the back of the book:
FUGLI is the system to make it happen! FUGLI stands for Friz's Uniform Gaming Line Instructions - the core rules system behind the Distant Worlds and Survivors of the Fire role-playing games by FRIZ GAMES!
FUGLI covers it all – character creation, task resolution, combat, vehicle combat, environmental hazards, animals, weapons, armor, vehicles, gear, plus optional rules for creating your own psionics disciplines and schools of magic!
But the FUGLI Core Rulebook doesn’t stop there! There are also six campaign outlines the Director can use right away to get a fun campaign started or to run a one-shot pickup game for a session’s worth of excitement!
