Save the galaxy by destroying nuclear-absorbing octahedral crystals that have taken up residence around the sun. To accomplish this, you must blast your way through 9 sectors of space filled with kamikaze aliens, cloaked enemy ships, laser guided missles, regenerating crystals, and electromagletically charged particles to reach and destroy the "mother" crystal. The odds are rather extreme, but that's why the galaxy leaders chose a pilot with just the "right stuff" to complete the and mission... you.
