The Solnoid race and their foes met their demise in the ultimate conflict at Sigma Narse. However, their successors exist on Earth and have unfortunately inherited the same tragic fate that was prophesized long ago. It is now the year 2085. The Earth's cities are practically non-existent after the third world war erupted between the East and West. The mechanical weapons of destruction, produced by both sides, are now relentlessly hunting down the survivors of humanity. Old grudges between human factions have hindered an efficient resistance, leaving the evacuation of the surviving populace to Mars Base as the only hope for survival. Once there, they can slowly but surely rebuild and prepare to retake their original planet. Amidst the evacuees, a young woman bears the burden of her father's involvement in civilization's downfall. Unbeknownst to her, she also possesses the key to potentially save humanity. As fate guides new allies and companions to her side, a new Gall Force emerges and is ready to combat the impending doom.
