Catacomb 3-D

Catacomb 3-D (also known as Catacomb 3-D: A New Dimension, Catacomb 3-D: The Descent, and Catacombs 3) is a first-person shooter video game, the third in the Catacomb series, the first of which to feature 3D computer graphics. It was developed by id Software and originally published by Softdisk under the Gamer's Edge label, released in November 1991. The player takes control of the high wizard Petton Everhail, descending into the catacombs 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. It is 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 MS-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 Wolfenstein 3D. The game's more primitive technological predecessor was Hovertank 3D.
