Once, many millennia ago, the young, tranquil world of Darius was invaded by a race of star-hopping barbarians under the command of galactic tyrant, Belser. The peace-loving Dariusites were ill-prepared for such an invasion and most fell quickly. However, before the entire planet succumbed to Belser's domination, a brave young couple, Proco and Tiat, led a resistance effort and managed to escape with many of their fellow Dariusites to sectors of space that were still free. As the centuries passed, the descendants of this resistance movement multiplied and prospered, and populated many worlds. On Orga, a world of uncommon resources, they established the command center for the Galactic Federation, a governing body that united all the peaceful worlds of the galaxy. After a thousand years, the forces of Belser again decided to expand their empire and headed spaceward to conquer the people who escaped them centuries earlier. Branching ever outward, Belser seized control of even more planets in the solar system. Inspired by the legends of Proco and Tiat, two of the Federation's best pilots now ready their spacecraft for the long galactic battle that awaits them. These vessels, advanced technological miracles called Silver Hawks, are able to transform energy into powerful weapons and armament. It is your mission to pilot a Silver Hawk, defeat Belser's forces on each of the planets along your selected route, and reach Darius and destroy the formidable Alloylantern, a mechanical fortress from which all of Belser's technological strength springs. Belser's original world remains unknown, but the most noted scientists believe that it was largely oceanic because all of Belser's technology seems patterned after aquatic lifeforms.
