Luigi must once again team up with Professor I. Gidd to explore the treacherous floors of the haunted hotel as an unwilling hero and save his friends. He can rely on the Poltergust F-lu to help him. With it, he can blow away the nasty ghosts, throw them to the ground, and even summon his slimy green doppelgänger, Fluigi. Fluigi can overcome obstacles that Luigi cannot pass on his own. Switch between Luigi and Fluigi when playing solo, or play together with a friend, each controlling one of the two characters. If you're in the mood for multiplayer action, a visit to the Tower of Chaos is worthwhile. In this multiplayer mode, up to eight players can take on the challenges of the tower, either online or locally on up to four Nintendo Switch consoles.
