"You and other experienced intergalactic voyagers have heard about and shared the legend of Star Castle -- a mysterious fortress in a far away galaxy filled with incredible riches and surrounded by revolving walls of shimmering solid gold. Yet no one, until now, has ever actually seen the Castle -- or lived to tell about it!

As you approach, you are overwhelmed with the beauty of the Castle but you suddenly realize that the golden walls hide a deadly arsenal. To survive you must destroy the walls and the powerful Energy Cannon they shield. Perhaps you will be the first to survive the Star Castle's arsenal and prove the
legend true. Perhaps not!"
