Patently Dangerous FM addon - The Dark Mod (Standalone) for Doom III

"Nobody said hypocrisy didn't have its uses. The Inventor's Guild, always so secretive about its own inventions, isn't beyond a little espionage when it comes to the inventions of others. They've hired me to steal the design notes from a young man named Soren Rikk, just on the outskirts of the Highlands Ward. He's reputed to have made a huge discovery in a field the Inventors have some interest in. It should be an easy job. Soren isn't known to be a dangerous person."
