About Freedoom

Freedoom is a project that aims to provide all the content needed to form a complete, entirely free/libre game for the Doom engine: levels, graphics, sounds and music. The homepage describes it as designed to be compatible with most custom levels, music, graphics and other modifications made for the original Doom games by fans over the decades.

The site offers the game for download, a manual, screenshots, and channels for help and discussion such as a forum, Discord and an issue tracker. The most recent release listed is version 0.13.0 (2024-01-29), which focused on improved vanilla compatibility, removal of Boom features, reduced hall-of-mirrors effects, new levels and monsters, new music, and colorblind-friendly keys and key indicators. Savegame buffer overflow errors remain, and Final Doom compatibility has been de-emphasized.
