Even after 3 years, Black Mesa remains as one the most highly anticipated mods for any game engine available.

While known by some hardcore Black Mesa fans, we'd like to officially state that we've upgraded to the Orange Box build of the Source engine. We're also excited to announce that we've dropped Counter-Strike: Source as a requirement for Black Mesa, and from now on, the only thing you'll need to play the mod is a Steam account with any Source engine game installed! Black Mesa is now running completely off of our own content and base Source shared content, and we felt the vastly increased user base more then justified creating all the extra assets needed to make this switch.

Hopefully moving to the Orange Box build won't delay the game too much longer.
