The game was in development for a few years with no release until finally in September 14, 2012, the game was released as a downloadable source mod using Source Engine SDK Base 2007. Valve Software, however, did not like the idea of the project due to it including the name Source which implies the game is officially endorsed by Valve. At the time, the game was originally using the Counter-Strike: Source game for its base. Black Mesa originally started as most other popular source mods do: as a listing on ModDB.īlack Mesa's development began when two seperate projects ( Leakfree and Half-Life: Source Overhaul Project) decided to merge and call itself Black Mesa: Source.
