For those of you that have not been keeping with the Black Mesa, its a fan made modification that runs on the Valve Source engine.
Its more then just a fan made modification, Black Mesa is supposed to be a remake of the original Half-Life.
Black Mesa is scheduled to be released September 14th. Download servers will be announced shortly before the download goes live.
My only hope is that Black Mesa lives up to the hype.
Half-Life was released in November 2004. Development on Black Mesa started around January 2005. I hope the game shows 7 1/2 years of quality.
