BFG-10000 (Doom Eternal)

The BFG-10000 is an orbital defense weapon system stationed on Phobos. The weapon was designed by Dr. Samuel Hayden as part of the anti-demonic defense grid, and was built on top of the UAC's preexisting mining and communication relay outpost. At coordinates 1°N 49°W, the BFG-10000 is settled in Stickney, Phobos' largest crater. The UAC Board of Directors ordered the construction of the weapons system shortly after the destruction of the Argent Facility on Mars.
