Site 2

Site 2 is a UAC dig-site on Mars. It is the smallest dig-site and has the smallest Caverns in the UAC. This site was cleared out and closed prior to the events of Doom 3. All the artifacts discovered were sent back to Earth for further study.

The Caverns aren't really seen in the game, only the Warehouse. But in Pierce Rogers' video, it shows some temples seen in Site 2. The only entrances/exits known is the Monorail Station.
