Source 2004 is the original build of the Source engine that Half-Life 2, Half-Life: Source and Counter-Strike: Source shipped with. It was succeeded by the Source 2006 engine branch with the release of Half-Life 2: Episode One.

No current Valve titles hosted on Steam use this branch, and it is outdated.

One game, Vampire: The Masquerade – Bloodlines, currently on Steam, still run on the custom version of the engine that was similar to the Half-Life 2 Beta leak, but with proprietary texture format and BSP version 17, aswell as being the first Source game to use Bink for it's startup video, and another game, SiN Episodes, used a last?^[confirm] build of Source 2004 containing few commands which was related to the HDR Rendering that was non-functional ("mat_hdr_enabled").
