Star Frontiers is a science fiction role-playing game produced by TSR from 1982 to 1985. The game offered a space opera action-adventure setting. Fictional setting Star Frontiers takes place near the center of a spiral galaxy (the setting does not specify whether the galaxy is our own Milky Way). A previously undiscovered quirk of the laws of physics allows starships to jump to "The Void", a hyperspatial realm that greatly shortens the travel times between inhabited worlds, once they reach 1% of the speed of light (3,000 km/s). The basic game setting was an area known as "The Frontier Sector" where four sentient races (Dralasite, Humans, Vrusk, and Yazirian) had met and formed the United Planetary Federation (UPF). A large number of the star systems shown on the map of the Frontier sector in the basic rulebook were unexplored and undetailed, allowing the Gamemaster (called the "referee" in the game) to put whatever they wished there. Players could take on any number of possible roles in the setting but the default was to act as hired agents of the Pan Galactic corporation in exploring the Frontier and fighting the aggressive incursions of the alien and mysterious worm-like race known as the Sathar. Most published modules for the game followed these themes. Publication history The Star Frontiers (1982) basic boxed set was later renamed Star Frontiers: Alpha Dawn after the expansions began publication. It included two ten-sided dice, a large set of cardboard counters, and a folding map with a futuristic city on one side and various wilderness areas on the other for use with the included adventure, SF-0: Crash on Volturnus. A second boxed set called Knight Hawks (1983) followed shortly. It provided rules for using starships in the setting and also a set of wargame rules for fighting space battles between the UPF and Sathar. Included were counters for starships, two-ten sided dice, a large folding map with open space on one side and on the other a space station and starship (for use with the included adventure), and the adventure SFKH-0: Warriors of White Light. This set was designed by Douglas Niles (who also designed the D&D wargame Battlesystem, released two years later). Adventures printed separately for the game included two more adventures set on Volturnus (SF-1: Volturnus, Planet of Mystery (1982) and SF-2: Starspawn of Volturnus (1982) continuing the adventure included in the basic set), SF-3: Sundown
