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.
The origin of the games is Catacomb by John Carmack for the PC and Apple II. This was a two-dimensional game utilizing a third-person view from above, released in 1989–1990. It was followed up with Catacomb II, which used the same game engine with new levels. The first release of Catacomb 3-D was called Catacomb 3-D: A New Dimension, but it was later re-released as Catacomb 3-D: The Descent, as well as Catacombs 3 for a re-release as commercially packaged software (the earlier versions had been released by other means such as disk magazines and downloads). The game creators were John Carmack, John Romero, Jason Blochowiak (programmers), Tom Hall (creative director), Adrian Carmack (artist), and Robert Prince (musician). The game was programmed using the Borland C++ programming language.
id Software's use of texture mapping in Catacomb 3-D was influenced by Ultima Underworld (still in development at Catacomb 3-Ds release). Conflicting accounts exist regarding the extent of this influence, however.
