Freedoom map07 by Boris Iwanski
Not to be confused with FreeDoom.
Freedoom is a project to create a free software/open source Doom 2 IWAD file. Combined with the free source code, this results in a complete Doom-based game. All material in the Freedoom project is released under the modified BSD license, so other projects may reuse any of the Freedoom material for their own purposes as they wish. In fact, this is a secondary goal of the project.
Levels for the project are Boom-compatible; some use Boom extensions. As such, a Boom-compatible source port is necessary to play the game, and Freedoom cannot be played with the original source code.
Two subprojects also exist. One is to create a free shareware WAD file as a smaller demo of the project, and the other is FreeDM, which uses the resources from Freedoom to create a free deathmatch game.
The project was started and originally maintained by Simon Howard and Jon Dowland. FreeDM was originally maintained by Jim "Rellik" McDougald. Both are now collectively maintained by Mike RS.
Freedoom and FreeDM are still under development.

- The Mancubus has been replaced with a slime-like monster with a distorted face, with the fireball launcher on each "shoulder".

- The Spider Mastermind now looks like a tank with 6 legs, with the visible head, body, and arms seemingly controlling the tank, the chaingun located in the stomach of the monstosity.

Easter eggs
- Richard M. Stallman features as the replacement for the boss brain (sprite).
- The texture SP_FACE1 is derived from pictures of prominent members of the Doom community (texture).
- In versions up to 0.5, the pink fish popular in some Doom community forums is used instead of Commander Keen (sprite). The sprite was removed after 0.5 due to trademark concerns.
Commercial derivatives
The BSD-type license used by Freedoom allows reuse in commercial projects; and at least two different companies combined Freedoom with the Doom Classic port to create games sold for the iPhone or iPad.
