Death Pit

Despite the dramatic artwork and name, Death Pit doesn't have much of a plot to speak of - explore the mines gathering as much gold as possible and the precious gem buried deep in the mine complex just behind the last of the dragons. As well as the aforementioned dragons, you need to deal with spiders, bats and all manner of unknown creature not to mention the usual perils you expect to find in mine shafts like flooding and rough terrain.
