Freedoom

Freedoom is a community-driven project that provides free game data for Doom engine games. It offers WAD files intended to serve as a complete, free replacement for the proprietary data used by the classic Doom series, enabling legal distribution and play of Doom-based software and engines.

The project collects content in phases, including Freedoom Phase 1 and Freedoom Phase 2, with new levels, textures, sounds, and artwork contributed by volunteers. The assets are designed to be used with any Doom-compatible engine and can be loaded by engines such as PrBoom+, Zandronum, Chocolate Doom, and other source ports. Freedoom is meant to complement or substitute the original Doom data in compatible setups.

Freedoom's content is released under licenses compatible with free software principles, ensuring freedom to use, modify, and redistribute. The project emphasizes openness, community collaboration, and ongoing updates available through the official site and repository hosting.

As a non-official effort, Freedoom is not affiliated with id Software. It aims to provide a freely distributable substitute for Doom data to support free distribution of Doom-based engines and mods while fostering a community around open, replaceable game assets rather than proprietary content. The project is commonly used by developers, modders, and fans seeking a legally shareable Doom experience that aligns with free software goals.
