See also:  Source/Engine versions - list of Source engine build numbers.

version is a console command available in all Source Source games. Prints version info in the Developer Console.

Previous Source games (including early Source 2013 games), and all games since Left 4 Dead engine branch Left 4 Dead engine branch, prints protocol version, exe version and exe build date like GoldSrc. exe build date can be also seen inside engine.dll when viewed using any text editors. Since Left 4 Dead engine branch (March 11, 2009 update), protocol version are tied to PatchVersion (NetworkVersion for Left 4 Dead 2). The Source engine build number is the number of days since November 7, 1998.

Newer version of Source 2013 games (except some titles like Garry's Mod) since late 2013 and 2014, aswell as Source SDK Base 2013 (both SP & MP, all versions) instead prints Build Label, Client/Server version, Network PatchVersion and Protocol version, which can be altered by editing steam.inf.[1]

Properties, formats, examples below.

Note.pngNote:In most cases, these versions can be changed by editing the steam.inf file. This is heavily discouraged, as it immediately renders the game unable to connect to any server for its version or for any other version (due to protocol differences), and prevent the game from playing demo files not matching the versions.

1. Early Half-Life 2 SteamPipe build (such as build 5288 / May 7 2013), prints version number and build date like previous Source branches. This was later changed in late 2013 (but doesn't applies to all Source 2013 games like Garry's Mod), many Source 2013 games now prints network patch version, along with client & server versions from steam.inf. The code which prints version number be only seen on both leaked full Source 2007 engine code in 2012 and full Source 2013 Multiplayer (TF2) code in 2020.
