You were part of an expedition to planet Mors. A desolate, dry planet, full of aliens. Your crew left you behind by mistake, and you are now stranded with nothing more than a blaster, and terrible collection of disco music from the eighties.
But there is still hope. There is a second ship that could take you back to Earth. Regretfully it was damaged during landing, and it can't take off. You need to find the missing parts, which are scattered all over the planet, repair the ship, and escape to Earth.
Try to survive the mortians and the terrible disco music. Collect all the missing rocket parts, and some valuable mortian gems along your way. Repair the ship, and escape!.
