Publisher's blurb
Blast your way through the alien mine fields! Defend the moonbases from an attacking alien armada! It won't be easy. To win you will need to mount a heroic assault on the alien mother ship.
Moonbase Io combines three exciting arcade adventures in one exciting game. The machine-language program developed by John Konopa uses advanced graphics and sound effects. Action is fast and exciting - varying levels of skill required to go from one part of the game to the next.
Beyond Software's arcade-adventures are the next generation in computer games for the Atari computer. A voice-activated program will help you meet and overcome the challenge - it may be an alien invasion, a fiendish murderer preying on a country village or a treasure trove buried deep in the shark-infested sea.
