Luigi's mansion 3: luigi's dream vacation turns into a ghostly—and gooey— nightmare. Luigi embarks on a dream vacation with mario and friends upon receiving an invitation to a luxurious hotel. However, his dream quickly becomes a nightmare when king boo reveals everything had been a ploy to capture mario and friends. With the assistance of professor e. Gadd once again, the reluctant and cowardly hero luigi traverses up and down treacherous floors of the now-ominous hotel on a quest to save them. Wield the upgraded poltergust g-00 to slam and blow away the ghosts' defenses, or summon gooigi, an all-green doppelganger that can help luigi overcome obstacles he can't get past alone. Interchange between luigi and gooigi as one player, or grab a friend and control one each. For more frenetic multiplayer action, race the timer to clear various objectives on a series of floors in scarescraper mode. Scarescraper mode can be played online* or locally with up to eight players on four nintendo switch systems (additional games required; sold separately).
