Black Mesa Research Facility

The Black Mesa Research Facility, or B.M.R.F. for short, is the headquarters of the Black Mesa corporation and located in New Mexico desert, USA.

History
The facility suffered a resonance cascade which opened a dimension to alien worlds, causing the aliens to infiltrate the facility and kill the personnel. The military were dispatched to the facility to contain it but found themselves outnumbered and ordered to pull out. The facility was believed to have been nuked by The G-Man, but this was just a cover as the government began to secure and move out technology and equipment developed at the facility.

Once the Combine invaded earth, they took over the facility and turned it into one of their base of operations, which was located nearby City 1. They planned to salvage the Black Mesa Scientists local teleportation technology which they had tried to perfect, but were unable to locate anything.

In July 202-, Paisley and Lily Hills were sent to the facility on an undisclosed assignment.

Following the Combine's defeat on earth, the facility became abandoned. Due to it still being presumed destroyed two decades prior, it was left to fall apart.

Nathan Johnson pursued Viktor Rascalov back in time to the Black Mesa Incident. The timeline was slightly altered to create a new reality in which the Combine didn't invade earth. The Black Mesa Research Facility was left abandoned after the invasion, with a new one established elsewhere.
