Built into and over several decommissioned nuclear missile silos, Black Mesa is the site of broad scientific research relating to theoretical, quantum, and particle physics, applied mathematics, robotics, genetics, biotechnology, trans-dimensional travel, teleportation, and other classified subjects. You can help by describing the files below.The Black Mesa Research Facility is a private research and defense contractor comprised of a massive complex built within the mountains of New Mexico, and is the setting of the original Half-Life, as well as Half-Life: Opposing Force, Half-Life: Blue Shift, and Half-Life: Decay.

The nearby Fuel Room contains the fuel and oxygen reserves provided for the Silo D-01 engines.Īt least one image in this gallery is not captioned. Silo D-03, Wind Tunnel (yellow-coded) contains a huge propeller and is accessed from the upper door inside Silo D-01. Silo D-02, Power Facility (green-coded) provides energy to Silo D-01 and is accessed through the lowest door of the central chamber. The other two silos are adjoined to this silo and can be only accessed through here. Three huge Tentacle creatures occupy the silo. This is where the engines are actually tested. It is the largest and most important of the three.

Silo D-01, Engine Testing (green-coded) is located in the middle of the silo. It is connected to the High Security Materials Storage Area by an old decommissioned rail system. It is a large abandoned Cold War era missile silo that houses the Experimental Propulsion Laboratory used for testing rocket engines. Silo D is a location featured in Half-Life in the chapter Blast Pit.
