Guard Hall

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 he is hit. Luigi must instead run past the knights to avoid them. In later missions, mice will crawl around the room, getting in the way of Luigi's progress. This hall leads to the Foyer.

In mission A-3, all the knights disappear by means of Spirit Balls. Coming back to this mission and using the Dark Light to reveal the statues makes 47 bills come out, making a total of 235 G.
