Stub

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

Prints version info in the Developer Console.

Previous Source games (including early Source 2013 games), contains protocol version, exe version and exe build date. Newer version of Source 2013 games (except Garry's Mod) since late 2013 and 2014, aswell as Source SDK Base 2013 (both SP & MP, all versions) instead prints Client/Server version, Network PatchVersion and Protocol version.^[1]

Properties, formats, examples below.

Note: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)
