The Cylons were created by man. They evolved. They rebelled.
40 years after the first Cylon War, the Cylons returned and laid waste to the Twelve Colonies. Gathering a ragtag fleet of civilian ships, the ageing Battlestar Galactica managed to escape the attack and set out to find the legendary home of the Thirteenth Tribe of Man - the planet known as Earth.
After months of relentless pursuit by Cylon forces, the Battlestar Galactica and the Colonial Fleet under her protection reunited with the Battlestar Pegasus, another survivor of the Cylon attack. Together they managed to strike back and destroy the Cylon Fleet's Resurrection Ship.
Enraged by the loss of the Resurrection Ship, the Cylons launch a massive counterattack against the Colonial Fleet. Caught unprepared, the Colonials attempt to jump away to safety, but something goes terribly wrong. The FTL drives of both fleets are overloaded by a massive pulse of energy, triggering an uncontrolled jump that throws them far off course.
In Battlestar Galactic Online, both the Colonial and Cylon fleets find themselves stranded in an unexplored area of space at the very edge of one of the galactic arms. Heavily damaged and critically low on resources, both fleets race against time to repair and rearm, struggling for control of systems rich in Tylium, metals and water. The Colonial fleet desperately searches for a way to escape and continue the search for Earth before the Cylons gain enough strength to destroy them once and for all.
