from the back cover You are Joshua MacKenzie, a young astronaut living at Ares Base on Mars in the year 2085. While exploring, you find the remains of a renegade society that lived thousands of years ago. Among those remains are Searcher, a fantastic ruby computer/laser weapon, and another defense computer that is preparing to destroy the new "invaders," the Earth people at Ares Base, and perhaps the Earth itself. The destruction is about to start, and only you can stop it. You use Searcher's help to translate Luntarian writing and fight strange and powerful robots.
