Catacombs 3

The player takes control of the high wizard Petton Everhail, descending into the catacomb of the Towne Cemetery to defeat the evil lich Nemesis and rescue his friend Grelminar. Catacomb 3-D is a landmark title in terms of first-person graphics. The game was released in November 1991 and is arguably the first example of the modern, character-based first-person shooter genre, or at least it was a direct ancestor to the games that popularized the genre. It was released for DOS with EGA graphics. The game introduced the concept of showing the player's hand in the three-dimensional viewpoint, and an enhanced version of its technology was later used for the more successful and well-known Wolfenstein 3D.
