The Unholy Trinity



The Unholy Trinity, or Trinity College, is a single-level PWAD designed by Steve McCrea, Simon Wall, and Elias Papavassilopoulos. As part of their 10 Years of Doom feature, Doomworld named it one of the ten best WADs of 1994.

This map uses a large number of custom textures to create striking "photorealistic" buildings and courtyards, modeled on the real Trinity College in Cambridge, England. It also features an original animation sequence and a replacement music track, which is a partial rendition of "Toccata and Fugue in D Minor" by Johann Sebastian Bach.

Trinity was originally released on August 22, 1994 (as "trinity.wad"). A second version ("trinity2.wad") was issued September 4, 1994 to fix a bug involving texture patches.

Technical information
The original WAD is not compatible with Ultimate Doom, but there is a patch ("trinityu.wad") that fixes this.

Inspiration and development
Rial Fletcher released a Doom II conversion of Trinity in November 1996. Olivier Montanuy released a Heretic version in March 1995 (not February 1994 as the readme file claims), with the music track removed as it tended to crash the game.

Trivia

 * With respect to the real college, compass heading has been rotated 90 degrees counterclockwise (i.e. the is in the southwest corner, but should be in the northwest corner).
