Black Mesa is a remake of Valve Software’s award-winning PC game, Half-Life on the Source engine.
During its eight years in development, Black Mesa has been featured in several video game publications and received direct attention from Valve. Due to its long development time the modification has recently become notable for its delays, and dwindling updates on the status of its completion.
Today is the day finally of the first release of Black Mesa as a free download. We soon expect it to be available for free on Steam aswell.
Note: Also make sure you have the Source SDK base installed in Steam!
