The story is set in the year 2704, when the ASFAR (Alliance of Space-Faring Alien Races), of which Earth is a member, suddenly turns against Earth and their fleet ravages the planet, starting a war. The player flies a powerful starfighter, the TV-202, in a series of missions to defeat the enemy. In Episode 3, the player learns that a huge supercomputer known as X.I. (Xenocidic Initiative), located on Proxima Seven, is responsible for the war. Their final mission is to eliminate it. A hidden mission can take place after the main plot only in the CD ROM version where the player must investigate a sudden metamorphosis of an unknown nearby planet and destroy the force that changed the face of the planet. It is revealed here that this force drove a man named Sy Wickens into insanity, and how the X.I. Supercomputer had "accidentally" digitized Sy Wickens' persona.
