Luigi's Mansion: Dark Moon is still a couple months away, but Nintendo outlined a first for Mario's brother (outside of Nintendo Land, at least): Multiplayer. Specifically, Dark Moon will feature both local and online multiplayer with Download Play capabilities.
Hunter Mode puts players in control of different colored Luigis and challenges them with hunting down ghosts and using teamwork to clear each floor within a set time limit.
