In a desperate struggle for survival, the Earth Federation finds its network of space stations under relentless assault from the hostile Zylon armada. Piloting an advanced fighter craft, you must navigate the vast reaches of space to intercept enemy fleets before they can close in on and annihilate the Federation's vulnerable outposts. Combat takes a serious toll on your vessel—each enemy strike damages critical systems like your defensive shields, targeting computer, weapons array, and sensors—and sustained damage threatens to drain your ship's power reserves entirely, leading to catastrophic failure. Between skirmishes, you'll need to seek out repairs and restore your craft to full operational status, balancing the urgency of returning to battle against the necessity of keeping your fighter combat-ready. The fate of Earth's defensive infrastructure depends on your ability to outmaneuver and outgun an implacable alien threat.
