Utilizing the Source engine and its endless array of possibilities and powers, Black Mesa will throw you into the world that started the Half-Life continuum and introduced Gordon Freeman, the gun-toting, bullet-dodging Ph.D. in Theoretical Physics. Check the About the Mod page for more details. br The Single-Player portion of the game was released exactly at September 14, 2012 - 8:47 AM MDT [1] (a reference to the time that Gordon Freeman is riding the tram), and the soundtrack was released two weeks before the actual game release date [2]. See the History of the Mod for more info about its development history.
