The Terran Fleet is developing a new prototype starfighter, the RaptorX, and the player is a test pilot of that prototype. Suddenly, the Xidus Armada Fleet, the Terran Fleet's arch enemy (ever since Galactix), launches an all-out surprise attack on the Terran Fleet that catches them with their guard down, destroying all Raptor fighters in the process, save the few RaptorX prototypes which were away being tested. Now the player must battle through the Xidus Fleet alone, destroy their ultimate weapon, codenamed the DemonStar, and save the rest of the Terran Fleet.
