At the start of the 22nd century mankind has colonised the planet Xerxes in the Unicorn solar system. Using construction machinery and automated robots the colonists have built a huge self-sufficient complex. They have established contact with the Earth and constructed generators for oxygen and ... put a central computer system into operation. This moment was their undoing, as the robots became stronger and stronger until they took over the whole planet. As a specially trained soldier, you have been chosen to thoroughly investigate this alien planet. You still have no idea what is waiting for you when you arrive.
