In a nutshell, play Half-life the way we think it was meant to be played!

Experience over 2,000 choreographed scenes and over 6,500 lines of dialogue from all new voice acting!
Subtitles in English, Italian, Spanish, Norwegian, German, and Finnish!
Immerse yourself in an all new soundtrack and over 2,300 custom sound effects!

What's new in the Steam Release?
The Steam release of Black Mesa includes various fixes, upgrades, and new features since Black Mesa's mod release.
Heavily updated single player experience - The Black Mesa 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 Steam release of Black Mesa, but will be included as a free update when it is ready.
Black Mesa Multiplayer - Fight with or against your friends, in two game modes across six iconic maps from the Half-lfie Deathmatch universe: Bounce, Gasworks, Lambda bunker, Stalkyard, Subtransit and Undertow.
Custom Modding Tools - Use the same tools the developers used to create your own mods, modes, and maps for Black Mesa and Black Mesa Multiplayer...
Fully integrated Workshop - ...and then share your work on the fully integrated workshop!
Complete Steam integration - Collect trading cards, backgrounds, emoticons, achievements, and everything else you would expect out of a Steam integrated game.

Why are we using Early Access?
Making a game with the scope and scale of Black Mesa is a massive undertaking. Back in 2012 we made the decision to release what we had completed up to that point, and were blown away by the communities response, feedback, and improvements to our work. We want to keep that relationship alive and well by using Early Access as a tool for allowing our community to participate in the final phase of Black Mesa's development.
