Medal of Honor Underground begins in 1940, not long after Germany crushed the French military and overran the country. Gamers are introduced to Manon who has just witnessed her house destroyed and hometown occupied. With nothing left to lose, she joins one of the many clandestine resistance movements that have taken root throughout her homeland during the early days of the occupation. Over the course of the game players will experience her ascent from a na?ve volunteer to a seasoned veteran who is ultimately recruited by the Americans for the Office of Strategic Services (OSS), where she will eventually play a key role in the Liberation of Paris.
