Technical notes
Note:Although Source mods are often described as being "for Half-Life 2", they actually use Source SDK Base. SDK Base is available to anyone who owns any Valve Source game and provides all of Half-Life 2's content (except maps and vcd scenes) on a static branch of the engine.Note:As of May 26 2010, the branch of Source under which Half-Life 2 originally ran (
/
) no longer exists on Steam. Very, very old mods which base themselves directly on the game (as opposed to Source SDK Base) are unlikely to work any more!. This also meant that support for running HL2 on Windows 9x/ME/2000 have been also dropped.Note:The Half-Life 2 Collectors Edition, which ships with Source 2004 version of the game, does not require Steam to run or update (similar to latest version), which meant that it will run on systems with Windows 2000 and earlier.Note:The 64-bit Windows version of Half-Life 2, which existed around 2005-2006, is no longer available.
