Fallout: 10 Most Evil Companies 

Usually, the Fallout universe is based in real-world science, not typically incorporating much of the paranormal, but the employees of Dunwich Borers have a uniquely spooky and unexplainable story.

Dunwich Borers was a marble quarry before the war but deep in its underground caverns the player can find a number of mysterious ancient artifacts that makes one question if the company was really just here for the marble.

It gets creepier though. As the player progresses through the excavation site, they see multiple visions showing cult rituals performed by the old staff of the quarry, and later learn that one of the station managers, Tim Shoots was luring employees into the cavern for some unknown purpose involving the artifacts.

Overall, it would have been cool to see more of this particular story in Fallout 4 as we never get an explanation on the occult magic that Dunwich Borers seemed to be trying to harness.
