Your mission is simple: just blast your way through the Astro-Mine mazes collecting star crystals to earn valuable space dollars! Beware, the aliens want them as bad as you do! The aliens have two types of ships. The Harvester and the Destroyer. Harvesters are relatively harmless to you, they just want to collect the crystals. So shoot them before they escape! Destroyers want nothing more than to destroy you, so destroy them quickly! Your fighter is equipped with The Spin Attack. Use this special attack when surrounded by alien ships or to harvest crystals quickly in confined areas! Your fighter also has a shield that draws from it's own power cells, so try to avoid collisions with astro walls, enemies and plasma shots! If your power runs out you will have no shield or ship power and your fighter will be destroyed. Thus, ending your star crystal career!
