The inhabitants of the three worlds in the Alpha 1 Solar System have been at war for seven months before hostilities cease upon the threat of invaders from the artificial world NGC-1611. The Alpha 1 Federation gathers the system's best defenses in an effort to repel the invasion. Two mechas and a self-aware robot are dispatched to NGC-1611, charged with the task of destroying the invaders' power source and, if possible, locating the legendary weapon, Xardion, in the process.
