Richard Davis

Dr. Richard S. Davis is a background character in Doom 3. He was a UAC archaeologist assigned to Site 3 and a colleague of Dr. Pierce Rogers. Davis was responsible for discovering a map in the ruins. The map had been built into the ceiling of the chamber. After studying the map, he determined that it was a map of the Solar system, and that it showed a link between Mars and Earth. He speculated that the Ancient Martians who survived the demonic invasion teleported to Earth, and that they might be the ancestors of modern Mankind.

Davis is never met in the game. He was most likely killed in the demonic invasion. His PDA can be found in Site 3 - Analysis Facility in the lab section of the base.
