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No current Valve titles hosted on Steam use this particular engine branch as it is outdated.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

Availability

Source code for this branch is no longer officially available. Most Valve games introduced with Source 2004 are now currently using Source 2013 Singleplayer or Source 2013 Multiplayer.

An archive of the 2004 SDK is available on GitHub.
