Doom Bible



The Doom Bible is the original design document for Doom, written by Tom Hall in 1992.

Some bits and pieces from the Doom Bible show up in various places:
 * The prefixes TROO and SARG on IWAD lumps for the Imp and Demon come from their Doom Bible names: Demon Trooper and Demon Sergeant.
 * The Unmaker appeared in Doom 64.
 * Of all the proposed episode names, only Knee-Deep in the Dead made it into the final game. It was originally to be the third episode of six.
 * The game originally took place on a planet called Tei Tenga. Some of the Doom computer panel textures still contain the text "UAC BASE TEI TENGA". The 1995 3D Realms game Terminal Velocity also featured a planet called Tei Tenga.
 * All of the playable characters in Rise of the Triad, a contemporary of Doom, had origins in the Doom Bible. Some had their names altered, and one only appeared as a possible name, but one or two were unchanged from their original descriptions.
 * In Strife, there is a place where the player must use a severed hand to unlock a door. This was also proposed in the Doom Bible. (Some observers believe this to be a coincidence.)
 * In the Doom movie, the BFG 9000 is named "BFG 3.14"; The original description of BFG can be found in section 14 of the document. (This likewise can be a coincidence.)
 * Likewise possibly coincidentally, Sarge uses a severed hand to unlock the BFG room in the movie.
 * 1) This is likely not a coincidence however, as Sarge finds the arm in a different location in the movie, and brings it back to unlock the door he found before. Acting much like the mechanics of the early game in finding a locked door with something behind it you want, finding the key later, and going back.
