Whereas the first ''Star Control'' stores most of its lore in the instruction manual, ''Star Control II'' continues the story with a rich in-game experience, playing through events after the Alliance is defeated by the Hierarchy.<ref name="HG101series2" /> In the last phase of the war between the Alliance of Free Stars and the Hierarchy of Battle Thralls, an Earthling ship discovered an ancient [[Precursor (Star Control)|Precursor]] subterranean installation in the Vela star system. A massive Hierarchy offensive forced the Alliance fleets to retreat beyond Vela, stranding the science expedition, who went in to hiding. Decades later, with the help of a genius child born on the planet, the colonists activated the Precursor machinery and found out that it was programmed to build a highly advanced but unfinished starship, which could be piloted only by the now grown genius child, who alone could interact with the Precursor central computer. The new ship set out to Sol to make contact with Earth, but shortly before reaching Sol the little fleet was attacked by an unknown probe; The expedition commander, captaining the expedition's Earthling Cruiser, intercepted the alien ship before it could damage the defenseless Precursor starship, but was killed in the short fight, leaving the genius young man in command.<ref>{{cite web|author=Hall|first1=Larry|last2=Wagner|first2=Jeff|last3=Friedland|first3=David|date=1991|title=Star Control Manual (Sega Version)|url=https://segaretro.org/images/0/0b/Star_Control_MD_US_Manual.pdf|access-date=October 14, 2020|publisher=Accolade}}</ref>

The player begins the game as the commander of the Precursor starship, who returns to Earth to find it enslaved by the Ur-Quan. The Captain gains the support of the skeleton crew of Earth's caretaker starbase and ventures out to contact the other races to find out what's happened since the end of the war and try to recruit allies in to a New Alliance of Free Stars against the Ur-Quan. The Captain quickly discovers that the rest of the humans' allies in the war against the Ur-Quan have either been eradicated, put under slave shields, or put into service as Ur-Quan battle thralls. As the player progresses, it is revealed that the Ur-Quan are fighting an internecine war with the Kohr-Ah, a subspecies of Ur-Quan who believe in eradicating all life in the galaxy, as opposed to enslaving it. The winner of this war will gain access to the Sa-Matra, a Precursor battle platform of unparalleled power. The player must take advantage of the Ur-Quans' distraction to contact and recruit alien races into a new alliance, gather resources and build a fleet, and find a way to destroy the Sa-Matra, before the Ur-Quan finish their war and become unstoppable.

The Captain resolves issues several of the races are facing, or exploits their weaknesses, to get them on their side. Notably the Captain finds the Chenjesu and Mmrnmhrm on Procyon undergoing their own plan to merge in to a composite species powerful enough to defeat the Ur-Quan, and captures a psychic alien Dnyarri, which the Captain discovers is a member of the race that brutally enslaved the galaxy millennia ago, causing the Ur-Quan's hegemonic and genocidal rampage around the galaxy. The Captain uses a Precursor Sun Device to accelerate the merging of the Chenjesu and Mmrnmhrm to create the Chmmr, who amplify a Precursor [[terraforming]] bomb, allowing the Captain to sacrifice his ship to destroy the Sa-Matra and defeat the Ur-Quan. After escaping the ship through a pod, the explosion incapacitates the commander for some time, until he later awakens at the medbay in the Earth Starbase. There, he learns that the loss of the Sa-Matra was a crippling blow to the Ur-Quan and witnesses the deactivation of the slave shield over Earth, revealing its true colors to space.
