In December 1973, the deep space probe Pioneer 10 passed Jupiter and left the solar system for deep space. It carried a plaque informing extra-terrestrial beings of the whereabouts of the planet Earth. In 3021AD Pioneer returns aboard an alien space craft wanting to contact Earth. Unfortunately, Steg pirates have boarded and disabled the craft, resulting in the ship's computer setting the self-destruct mechanism.
You are the first person to reach the ship after it has crash-landed on Earth. You have a limited time to disarm the self-destruct mechanism before it destroys the planet. On evacuation the alien crew have left behind various weapons and objects which will help you with your mission. They will be revealed by solving and completing the various tasks but you must hurry. Good luck...
