The Black Mesa Medical Lab is a Black Mesa Research Facility location featured in Half-Life: Opposing Force.


The Black Mesa Medical Lab appears to be a medical research facility. The area also houses a room where laser experiments with optical mirrors take place.


After the Osprey Heliplane carrying him and his platoon crashes, Adrian Shephard wakes up in an infirmary. He and his wounded comrades were taken here after they were attacked by the alien creatures. The area appears to be still under the control of Black Mesa personnel, who take care of wounded Marines and also study Headcrabs. Adrian is then sent to the crash site and radio for help.

Behind the scenes[edit]

Except for the infirmary, the actual name of that area is not given, although the Black Mesa Announcement System refers to a "Medical Laboratory 6" in the area.


The room where the first Otis security guard is found features a computer that will display a BSOD after pressing the Use key several times.
