The Guard Hall is a room in the Gloomy Manor in Luigi's Mansion: Dark Moon. In this hall, there are multiple knights that wield their sword in front of Luigi if he tries to walk past, which will deal him 20 HP if hit. Luigi must run past the knights in order to not get hit. In later missions, mice will crawl around the room, getting in the way of Luigi's progress. This hall leads to the Foyer.
