Luigi's Mansion 3

Luigi's Mansion 3 is an upcoming game in the Luigi's Mansion series for the Nintendo Switch, set to release sometime in 2019. Unlike previous games in the series, the game takes place in a haunted hotel rather than an actual mansion.

Story
Luigi, Mario, Princess Peach, and various Toads are invited to a hotel called the Last Resort. Soon after they arrive, everyone but Luigi goes missing, having been turned into paintings by King Boo. To save them, Luigi has to navigate the many floors of the hotel by collecting the elevator buttons. He also needs to defeat the ghosts with the help of Professor Elvin Gadd, using a new Poltergust called the Poltergust G-00.

Gameplay
Luigi's Mansion 3 plays much like the previous entry in the series, Luigi's Mansion: Dark Moon. The Poltergust G-00 retains the basic qualities of the previous vacuums, as well as the Strobulb item and the Dark-Light Device. It also introduces new abilities, such as slamming ghosts on the ground or into each other, firing a grabable plunger with the Suction Shot, and creating a shockwave or being lifted up with Burst.

Gooigi, introduced in the Nintendo 3DS remake of the first Luigi's Mansion, reappears and is stored in the Poltergust G-00. Gooigi can be called upon to pass obstacles Luigi cannot, such as spikes and bars. However, it is weak to fire and water, and will lose all its health immediately if it comes into contact with them. Luigi and Gooigi cannot be controlled at the same time in single-player, but Gooigi can be controlled by a second player with the second Joy-Con controller.

The ScareScraper from Luigi's Mansion: Dark Moon also returns, allowing for eight-player multiplayer to clear floors as quickly as possible. The mode also features procedurally generated floors.

 * Mario Bros. (Game & Watch): The pizza boxes in the trashed room say "Since 1983," referencing Luigi's debut appearance in this game.
 * Mario Strikers Charged: In one of the hallways in the theater, a framed poster of Mario performing his Mega Strike can be seen.
 * Punch-Out!! (Wii): In one of the hallways in the theater, a framed poster of Little Mac in his victory pose with Doc Louis and Sandman in the background can be seen. By using his plunger to rip the painting, a boxing glove will come flying out which looks very similar to Little Mac's boxing gloves.
