Games Supported By The Source SDK

Directly supported games

The Source SDK supports editing for the following games directly:

• Half-Life 2
• Half-Life 2: Deathmatch
• Half-Life 2: Episode One
• Half-Life 2: Episode Two
• Counter-Strike: Source
• Day of Defeat: Source
• Team Fortress 2
• Portal
• Half-Life: Source

Note:Half-Life: Source requires you to manually add a new entry to gameconfig.txt and manually configuring Hammer.

Note:All games above now ships with Source SDKs by default, so Source SDK (211) is no longer required to be installed (and it was incompatible with Source 2013 games anywaty). However, SDK sample content for these games are only available when you install Source SDK (and they are located at SourceSDK\sourcesdk_content and sourcesdk_content inside SourceSDK\vpks\depot_211_dir.vpk).

The following games have their own Source SDKs or Authoring Tools:

• Alien Swarm: Reactive Drop
• Dark Messiah of Might and Magic
• SiN Episodes: Emergence
• Left 4 Dead (via Left 4 Dead Authoring Tools)
• Left 4 Dead 2 (via Left 4 Dead 2 Authoring Tools)
• Alien Swarm (via Alien Swarm - SDK)
• Portal 2 (via Portal 2 Authoring Tools)
• Counter-Strike: Global Offensive (via Counter-Strike: Global Offensive Authoring Tools)
  • No longer updated and replaced by Counter-Strike 2, but the game is still available by selecting csgo_legacy beta branch. Tools for the game are also available.

User-supported

• Black Mesa
• The Ship
• Garry's Mod
• Any Source SDK Base (2006, 2007) mods, and many Source 2006/2007/2009/MP games (via Source SDK application).

Unsupported games

The Source SDK does not support editing for the following games:

• Half-Life and other games using its engine aka GoldSrc (e.g. Counter-Strike).
• Half-Life: Alyx and other games using Source 2 (e.g. Dota 2)

Half-Life SDK should be used for GoldSource games such as Half-Life. It includes an old version of Hammer editor, 3.4, which should be updated to 3.5 manually, or use alternatives such as J.A.C.K..

Source 2 games should use their own Workshop Tools (Counter-Strike 2 Workshop Tools for Counter-Strike 2, Half-Life: Alyx Workshop Tools for Half-Life: Alyx, etc...). These ships with Hammer 5.x.

Note:Half-Life and other GoldSrc games can utilize some features of the Source version of Hammer 4.x world editor, though this is unsupported.
