Caverns Of Eriban

From cassette cover
As the pilot of a mine supply ship, your task is to enter the Caverns of Eriban to deliver supplies to the subterranean mining depots. On the planet's surface are five supply depots with chequered yellow landing strips.
If there is a white flashing light on top of the depot building, you can land and collect 5 supplies and refuel your craft. Avoiding hte many ancient defence mechanisms you must enter the Caverns and deliver the supplies. Any mining instalation requiring supplies will be displaying a red flashing light. Local flight control restruvtions allow you only to land on the yellow landing strips. Once you have supplied five depots you will need to return to the surface to restock with supplies.
