Long ago the Solnoid people vanished, wiped out together with their foes in the climactic clash at Sigma Narse. Yet their progeny remain on Earth, now burdened with the sorrowful fate foretold many years earlier.
The year is 2085.
East and West's third global conflict has turned Earth's metropolises into jagged ruins. The automated death engines forged by each side now scour the planet for any traces of humanity. Lingering enmities among human groups thwart a unified defense, leaving only one glimmer of hope: ferry the living to Mars Base. There they may reconstruct society and plot a return to their native world.
Among those refugees, a young woman bears the weight of her father's hand in society's collapse. Unbeknownst to her, she also holds the secret that could save them all. As fate summons new companions and allies to her side, a fresh Gall Force emerges to confront the looming annihilation. In the shadow of a dying sun, their resolve burns brighter.
