From the introduction:
Space Ranger is an RPG about playing the people the galactic Confederacy call when the job just has to be done right...the first time.
In a Galaxy of 10 trillion nearbaseline humans and 60 trillion other sentient, about a quarter of which belong to the Confederacy, occasionally doing things through the regular channels just won’t or can’t take care of the problem.
When that happens in the Confederacy somebody calls in the Space Rangers.
The system for Space Ranger is the based on the absolutely amazing system created by Steve Darlington for the Matrix RPG "THERE IS NO SPOON" with extra mechanics cribbed from "F.A.T.E." by Fred Hicks and Rob Donoghue of Evil Hat Games and
“Orbit” by Jeff Diamond of Psychobilly Games.
