A decade has passed since humanity's desperate struggle against the Drengin Empire and their Yor machine allies, who have since carved out dominion across the galaxy by subjugating or eliminating the civilizations that once united against their ancient foes. Earth itself remains protected by an impenetrable Precursor barrier, cut off from the wider cosmos—until 2242, when the Terran First Fleet emerges from a hidden pocket universe bearing powerful new weaponry and the mandate to shatter this imposed isolation. With advanced technology in hand, the fleet's commanders prepare to liberate enslaved worlds, challenge the mysterious Thalan threat, and drive the Drengin from humanity's doorstep. Lowering the shield marks the beginning of an ambitious galactic campaign that will determine whether civilization itself survives the Drengin's iron grip.
