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 released on September 4, 1994 to fix a bug regarding texture patches.

Technical information
The original WAD is not compatible with The Ultimate Doom. Steve McCrea created a patch ("TRINITYU.WAD") to address this compatibility issue and released it on September 13, 1995.

Inspiration and development
Rial Fletcher released a Doom II version ("D2TRINTY.WAD") on November 3, 1996. Olivier Montanuy released a Heretic version ("HTRINITY.WAD") on March 20, 1995 (not February 1994 as the readme text file claims), with the music track removed because it caused the game to crash.
