EnPro Plant

The EnPro Plant in Doom 3 provides the primary power to the Communications Towers and backup power to the entire Mars UAC Facility. The EnPro Plant houses the Main Plasma Reactor, and plenty of Plasma Guns that were created in this facility.

The only known entrance is from Alpha Labs. Exits exist to Communications Transfer and to the Mars City Service Sub-Level area (as a retcon introduced in The Lost Mission only).
