About the game


Relive Half-Life in this highly acclaimed, fan-made recreation.

Black Mesa is the award winning re-imagining of Gordon Freeman's landmark journey through the Black Mesa Research Facility. Re-experience the game that raised the bar for the entire game industry all over again!


The over 10 hour single player experience has greatly improved from the mod release; new visuals, new voice over, updated gameplay encounters, stability changes and more. Xen is not part of the Early Access release, but will be included as a free update when it is ready.

Expect tremendously detailed environments, old-school tough-as-nails combat, and a gripping story with memorable characters. The all-new soundtrack, voice acting, choreography and dialogue create a more expansive and immersive experience than ever before!


Fight with or against your friends, in two game modes across 10 iconic maps from the Half-Life universe including Bounce, Gasworks, Stalkyard, Undertow and Crossfire!
