Freedoom is a project to create a complete Doom II-compatible IWAD file. Freedoom aims to create a 'free alternative' combined with the GPL-licensed Doom source code this will result in a complete Free Doom-based game. The Freedoom project has already succeeded in creating a complete set of replacement textures for the original Doom games, as well as a large amount of extra material (sound effects, graphics, sprites, etc).
