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). The original homeworlds of the Dralasites, Humans, and Vrusk were never detailed in the setting and it is possible that they no longer existed. 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.
- Dralasites are short, gray amoeboid-like creatures (they are actually multi-cellular unlike true amoebas) capable of changing their form to a limited extent by extending and retracting pseudopods. Lacking a digestive system, they consume their food by surrounding and absorbing it. A network of nerves and veins intersects at a Dralasite's two eye spots. They cannot see colors, but have a well-developed sense of smell. They have a sense of humor that the other races often find strange or quirky, and a love of bad puns.
- Humans are a race of beings virtually identical to Earthly humans. The most notable difference between these and earth humans are that the humans of the Frontier have a 200-year lifespan (possibly due to the advanced technology of the setting).
- Vrusk are an insectoid race with eight walking legs and two five-clawed manipulating arms. Their ant-like heads included two antennae and two mandibles. They are omnivorous. They are noted for their logical minds and their society is structured as commercial ventures. Many Vrusk give their company name before their given name.
- The Yazirian race are anthropoids similar to various terrestrial apes. They are muzzled, lightly furred, and have patagia stretching between their arms and legs which they can use to glide over short distances in low gravity (their home worlds are all low-gravity). They are descended from a nocturnal species, and prefer to wear tinted goggles to protect their eyesight during the day. They are said to be rather violent and pushy, and have a custom to choose a "life-enemy", which could be anything; a company, person, or a concept. The fictional species was rehashed as Shadow People in TSR's later Dragonlance series of campaign modules and also as the Hadozee race presented first in Spelljammer and secondly in Stormwrack. Yazirians share several points with the High Martians of GDW's later Space: 1889 RPG. Yazirians, like Wookiees in Star Wars and certain game depictions of fantasy Barbarians, have a "battle rage" or a berserker state of mind.
- The Sathar are a race of mysterious, worm-like beings who are the enemies of the UPF (they are not intended to be used as a player race). They have wormlike bodies of 3 to 4 meters in length with two tentacular arms that end in fine tentacles for manipulation and two tentacles that end in paddles that can be used for heavy lifting (including acting as "legs", lifting the front of the creature off the ground in a humanoid-like stance). Their eyes have two pupils each, giving them good peripheral vision. The races of the Frontier know little about them other than their basic anatomy and the fact that they are hostile, as no live Sathar has ever been captured. Some of the behaviors and motives of the Sathar were revealed in the printed adventures for the game, and adventures commonly featured mercenaries working for the Sathar to undermine the UPF as villains.
- There are also other non-player races in the Star Frontiers universe, including many in the printed modules, but these five are the only races who developed space drive technology within the Frontier.
- Several new player races appeared in a late addition to the line, Zebulon's Guide to Frontier Space, and include the Humma (which resemble kangaroos), Ifshnit (akin to dwarves), Osakar (lanky, parthenogenic quadrupeds) and Mechanons (intelligent robots).
The game was a percentile-based system and used only 10-sided dice (d10). Characters had attributes rated from 1-100 (usually in the 25-75 range) which could be rolled against for raw-attribute actions such as lifting items or getting out of the way of falling rocks. There were eight attributes that were paired together (and shared the same rating to begin with)—Strength/Stamina, Dexterity/Reaction Speed, Intuition/Logic, and Personality/Leadership.
Characters also each had a Primary Skill Area (PSA—Military, Technological, or Biosocial) which allowed them to buy skills that fell into their PSA at a discount. Skills were rated from 1–6 and usually consisted of a set of subskills that gave a chance for accomplishing a particular action as a base percentage plus a 10% bonus for each skill level the character had in the skill. Weapon skills were based on the character's relevant attribute (Dexterity or Strength) but other skills had a base chance of success independent of the character's attributes. Many of the technological skills were penalized by the complexity of the robot, security system, or computer the character was attempting to manipulate (also rated from 1 to 6).
Characters were usually quite durable in combat—it would take several hits from normal weapons to kill an average character. Medical technology was also advanced—characters could recover quickly from wounds with appropriate medical attention and a dead character could be "frozen" and revived later.
Vehicle and robot rules were included in the "Alpha Dawn" basic set. A beneficial feature of the game was its seamless integration of personal, vehicle and aerial combat simulation. The "Knight Hawks" rules expansion set included detailed rules for starships. The basic set also included a short "bestiary" of creatures native to the world of Volturnus (the setting for the introductory module included with the basic boxed set), along with rules for creating new creatures.
Character advancement consisted of spending experience points on improving skills and attributes.
The basic boxed set was renamed "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" 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 and SF-2: Starspawn of Volturnus continuing the adventure included in the basic set), SF-3: Sundown on Starmist, SF-4: Mission to Alcazzar, SF-5: Bugs in the System and SF-6: Dark Side of the Moon. The last two modules (SF-5 and SF-6) were written by authors from TSR's UK division, and are distinctly different from the others in the series in tone and production style.
Adventures using the Knight Hawks rules included SFKH-1: Dramune Run and a trilogy set "Beyond the Frontier" in which the players learn more about the Sathar and foil their latest plot (SFKH-2: Mutiny on the Eleanor Moraes, SFKH-3: Face of the Enemy, and SFKH-4: The War Machine).
A late addition to the line was "Zebulon's Guide to Frontier Space" which introduced several additional races and radical changes to the game's mechanics. Of the three planned volumes of the Guide, only the first was ever published (in 1985), leaving the game in a partially-overhauled state. Gamers were given little to no practical advice on how to convert their existing characters to the new rules, and TSR never published any further products using the "Zebulon's" concepts.
Wizards of the Coast published many of the races originally found in Star Frontiers in their d20 Future supplement for d20 Modern.
A version of the setting called "Star Law", which uses the d20 system rules was published as an alternate campaign setting in the d20 Future book. It uses the species names of Vrusk, Dralasite, Sathar, and Yazirian, but is not actually the Star Frontiers setting.
