Black Mesa



Black Mesa is an American research corporation whose headquarters are located in the Black Mesa Research Facility, in the New Mexican desert.

Black Mesa is apparently helmed by the United States government, as the Great Seal can be seen on the ground of several lobbies of the Black Mesa Research Facility, and the United States Nuclear Regulatory Commission, as seen on several comlink status screens.

In When the Cold Breeze Blows Away, Black Mesa becomes a country and is now a member state of the Grand Alliance in order to defeat the Combine Empire and win the Black Mesa War for the Earth Freedom Fighters.
