Source 2004

This article or section is a stub. You can help by expanding it.

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No current Valve titles hosted on Steam use this particular engine branch, as it is outdated.

Vampire: The Masquerade - Bloodlines still runs on a custom version of the engine, similar to the engine used in the Half-Life 2 Beta leak. However, it uses a proprietary texture format and BSP version 17, and support Bink videos.

SiN Episodes also likely used the last?^[confirm] build of Source 2004, or possibly an early version of the Source 2006 branch previously used by Half-Life 2: Lost Coast, combined with Source 2004 code^[confirm], which contains few commands related to the HDR Rendering which was non-functional ("mat_hdr_enabled").
