UAC Mars Base

The UAC Mars Base is a UAC base on the planet Mars which features as the primary setting of the Doom. It is the center of the UAC's Argent energy research projects, which utilize interdimensional travel and portals to harness the energy of Hell for use by mankind.

Pre-release
Pre-release materials released by Bethesda in the wake of referred to the entirety of the Mars Base as the "Argent Facility," a name which was later reduced to only refer to the central energy extraction and conversion facility. It was said that research was undertaken there on diverse projects such as the portable electromagnetic particle accelerator, a technology which was said to be used in the plasma rifle. These materials also vaguely stated that the discovery of "artificial symbols" near the base marking the surface of Mars would serve as a catalyst for its invasion by the forces of Hell. Most of these details did not survive to the game's release.
