The Catacomb Abyss

You play the role of a magician, who is called upon by the townspeople to defeat his ancient archrival Nemesis again. After having defeated Nemesis in the past, his minions have erected a huge museleum in his honour, and as a result the townspeople are forced to live under a rule of horror. You must once again venture into the catacombs, defeat Nemesis and free the townspeople.
