Luigi receives an invitation to a luxury hotel. Mario and his friends come along. Within hours they are all captured by King Boo and sealed inside paintings. Luigi wakes up alone in a dark basement with his vacuum cleaner, a talking ghost dog named Polterpup, and absolutely no backup. This is, unfortunately, very on-brand for Luigi.

Luigi's Mansion 3 sends Luigi through seventeen floors of The Last Resort hotel, each one themed around a different location or era — an ancient Egyptian tomb, a medieval castle, a pirate ship, a rooftop garden, a haunted movie set — with a unique boss ghost at the top of each. The Poltergust G-00 vacuum captures ghosts through a combination of stunning them with a Strobulb flash, grabbing with the suction nozzle and slamming them against the floor to drain their health. Gooigi is a gooey duplicate of Luigi that can be summoned at will to solve puzzles requiring two characters simultaneously — squeezing through grates, standing on pressure plates, splitting up to hit switches on opposite sides of a room — and serves as a second player character for local co-op. Every floor has interactive details and secrets responding to the vacuum. The ScareScraper online mode sends up to eight players hunting ghosts across a procedurally constructed tower under a time limit. The Multiplayer Pack DLC adds floors and cosmetic content for both ScareScraper and the competitive ScreamPark mode.
