Luigi's Mansion 3 is an action-adventure horror game released for the Nintendo Switch console in 2019. It is the third installment in the Luigi's Mansion series, which are based around the character Luigi in a paranormal adventure.

The game retains the core elements of the previous games, such as the dark, ghoulish settings with supernatural themes, an action-adventure gameplay and sucking up ghosts that Luigi encounters on his adventures.

There are a number of new features, such as new skills to be learnt with the vacuum, the addition of a doppelgänger character named Gooigi for assistance on puzzle-solving in certain levels and the expansion of multiplayer features such as co-op and competitive play.

In this iteration of Luigi's Mansion, the green plumber who the player takes on the role of has to navigate his way through the haunted high-rise hotel block, featuring differently themed levels that incorporate puzzles and ghost catching to rescue his kidnapped companions. 


The gameplay is similar to Luigi's Mansion: Dark Moon with everything pertaining to Luigi and his way to hunt ghost, on top of that is added new ideas made for Luigi's Mansion 3 like Gooigi, which allows co-op play as well as allow the player to control a character with different abilities in single player. The world structure and the ghost themselves are based on Luigi's Mansion according to Kensuke Tanabe as he felt that this was one of the few thing missing from the second game.


Luigi, his Polterpup, Mario, Princess Peach and her court are invited to go on vacation in a gorgeous hotel. Their vacation plans are ruined as this is revealed to be a plot that King Boo had orchestrated to get his revenge on Luigi and capture his friends, as the green-clad hero finds the hard way when Princess Peach screams. (She and the rest have been captured and crammed into paintings.) Luigi investigates, finding that the hotel's gorgeous looks have faded. It has become spooky, and King Boo shows the paintings within whose depths Luigi's friends have been sealed within.

Now, Luigi must go through multiple floors, defeating various Ghosts to gain the Elevator Buttons that have been scattered around the Hotel, save his five hapless friends, and defeat King Boo again. Gooigi aids him directly, being able to be summoned form the new Poltergust G-00 that Luigi has. He and his gooey doppelganger can work together to solve puzzles that they cannot solve on their own. From his bunker, Professor Elvin Gadd provides hints that can be used as Luigi navigates the haunted hotels.

Eventually, Luigi saves his friends, and they all make their way up to the top of the hotel to save Princess Peach and defeat King Boo. King Boo turns the tables by summoning a giant painting and crams Mario, Professor Elvin Gadd, and the Mushroom Retainers (Toad included) into a giant painting. Luigi and King Boo square off for the final confrontation. Eventually, Luigi manages to get the upper hand by bashing King Boo's skull into the roof to damage the ghostly royal. However, King Boo AGAIN turns the tables by using his crown to supersize the painting, turning it into a Black Hole that sucks up the hotel as it grows huge. Regardless, Luigi manages to defeat King Boo and cram him inside the Poltergust G-00.

With King Boo gone, the hotel crumbles. However, Polterpup saves Luigi just before the Green Wonder breaks his skull. The Ghosts escape the container and try to destroy the jewel that was used by King Boo, but it fades away. The Ghosts regret their past actions, but Luigi and Professor Elvin Gadd (The latter, Mario, Princess Peach, and the Mushroom Retainers (Toad included) were saved earlier.) offer to rebuild the hotel for them. They agree and put construction helmets on their heads, though the Hammer eats his as the purple ghost looks at the Hammer funny.
