After having crashlanded on the planet of Oo-Topos and taken prisoner your goal is to break out of captivity, repair your ship and get away from the hostile planet. It's 1995 A.D., Earth time. An Interstellar Transport carrying power transfusion waste collided with a meteor, scattering its contents towards Earth's Sun. The transfusion waste ist so deadly that all life on Earth will be destroyed unless something is done to save it. But Earth, in a restricted travel zone, has neither the knowledge of nor the technology to cope with such a catastrophe. Your mission is to deliver the chemical seeds of a protective compound that will render the waste harmless. Your destination is Observation Labport 5V, a seemingly lifeless planet just outside of Eartth's Solar System. From there, the compound can be synthesized and secrectly seeded into the Earth's atmosphere. During the otherwise routine voyage, however, your ship was ensnared by a tractor beam and forced to land on the planetoid Oo-Topos. Hostile aliens boarded your ship and threw you in a prison cell. You must escape and recover your ship with it's valuable cargo. Life on Earth depends on you.
