Catacomb Abyss

'Catacomb Abyss was the sequel to Catacomb 3-D, and featured the same main character in a new adventure: since his defeat, some of Nemesis' minions have built a mausoleum in his honour. Fearful of the dark mage's return, the townspeople hire Everhail to descend below and end the evil. The environments are more varied than in Catacomb 3D, featuring crypts, gardens, mines, aqueducts, volcanic regions and various other locales. It was the only game in the series that was released as shareware, released by Softdisk in 1992.
