Luigi's Mansion 3 is an upcoming video game for the Nintendo Switch. The game will be released on October 31, 2019. Just in time for Halloween.
Luigi, Mario, Princess Peach, Toads, and Luigi's pet ghost dog Polterpup go on vacation in a luxurious hotel as a prize, but it turns out this was a scheme by King Boo, who captures Mario, the Princess, and the Toads. With Professor E. Gadd's newest invention, the Poltergust G-00, Luigi can suck up ghosts haunting the hotel to rescue his brother. This machine can also create a slimy double of Luigi called Gooigi, who makes a great Co-op partner.
