Luigi's Mansion 3

" Busting makes me feel good..."

Luigi's Mansion 3 is a third-person adventure game developed by Next Level Games for Nintendo Switch. The third entry in the Luigi's Mansion series, the game released on October 31, 2019, just in time for Halloween.

Luigi has been invited to an all-expenses paid vacation at the luxurious hotel and spa, the Last Resort. Taking Mario, Peach, and three Toads with him, along with Polterpup - from the first game - they arrives at a virtual palace, where their host, the generous socialite Hellen Gravely, welcomes them warmly and promises a holiday like none other. It seems too good to be true...

...which, of course, given Luigi's rotten luck, it is, because Hellen actually built the Last Resort with a specific clientele in mind - ghosts like herself, and is the biggest fan of Luigi's old enemy King Boo!

Now, once again, Luigi has to enlist the help of Professor E. Gadd, and armed with the Poltergust G-00 and his ectoplasmic partner Gooigi, Luigi has to conquer his fears, explore the ghostly hotel, and rescue his friends, which is much, much easier said than done...

Putting aside the mission-based structure of Dark Moon'', this game brings back to the more open-ended style of the GameCube original. Luigi must explore each themed floor of the hotel while fighting ghosts, solving puzzles, and defeating bosses to obtain elevator buttons that he can use to access more floors, meeting a strange cast of ghosts along the way. The upgraded Poltergust G-00 gives Luigi several more attack options, such as Suction Shot plungers, and he can now summon Gooigi to act as a second set of hands to reach new areas and provide extra firepower, cause he's gonna need all the help he can get. A two-player console mode can be used with Player 2 assuming Gooigi's role, while the ScareScraper multiplayer mode returns from Dark Moon, now supporting up to eight players at once so you can play with others online.

 * Ambiguously Evil: The only ghosts that are confirmed as truly evil in this game are King Boo and Hellen. For the other bosses, it's hard to say, seeing as the rank-and-file Mooks were brainwashed by King Boo's crown jewel. It's not clear what happens to most of the bosses at the end of the game when the standard ghosts are freed, so it's hard to tell.
 * Blob Monster: Gooigi is a benevolent example. He can ooze through bars or drains, walk on spikes, and reach areas where Luigi otherwise cannot go, and can do almost anything Luigi can. But he has only 20 hp and deactivates instantly if he even touches water.
 * Dragon-in-Chief: Hellen Gravely is the antagonist Luigi interacts the most with, but she is, in fact, King Boo's accomplice.
 * Canine Companion: Polterpup - from the first game - frequently appears to help Luigi. First he serves as a target during the tutorial stage. Afterwards, once Luigi gains some Golden Bones, he can revive Luigi like he did in the previous game. And he frequently shows up to give Luigi hints on hard puzzles.
 * Cats Are Mean: Hellen's beloved ghost cat Polterkitty gives Luigi a terrible time, swiping his hard-won elevator buttons after two boss fights and leading him on a chase to recover them. When found, she goes One-Winged Angel and turns into a vicious cat-beast.
 * Cute Monster Girl: Serpci and the three sisters Nikki, Lindsey, Ginny play it straight. Hellen is one too, although when she's angry, her makeup runs, giving her a hideous Game Face
 * Graceful Loser:
 * Amadeus Wolfgeist seems to think the Boss Battle is part of his performance, and if reduced to zero HP, makes a formal bow before he's sucked into the Poltergust G-00
 * Oddly enough, Hellen. Once she knows she's lost, she signals Luigi to wait a second so she can apply her makeup one last time, does so, and gives a "thumbs up" signal to tell him to finish her off.
 * Money Spider: The Gold Ghosts from Dark Moon return. Like before, they are very fast and very slippery, and successfully bagging one gives you a LOT of coins.
 * Phantom Zone Picture: Like before this happens to Mario, but also happens to Peach and the Toads. Also happens to Luigi in the "Good Night!" sequence.
 * Rooftop Confrontation: Where Luigi fights the Final Boss.
 * Slapstick Knows No Gender: Luigi has some new moves that border on brutal, like grabbing a ghost and slamming it on the floor multiple times, even using it to hit other ghosts, and he'll gladly use this maneuver on Hellen, Serpci, or any of the other female bosses.
 * Sore Loser: Dr. Potter, the boss of the Garden Suites. When Luigi successfully catches him, his last act before being vacuumed up is to throw the elevator button on a ledge he assumes is inaccessible to Luigi. {{spoiler|It isn't, if Luigi waters a nearby plant he can use as a ladder.
 * Video Game Cruelty Potential:
 * You can flash your Strobulb at Professor E. Gadd or Mario (after rescuing him) to make them make funny faces. When using Gooigi, you can do the same to Luigi, but it doesn't work the other way.
 * Morty isn't a bad ghost, giving you the elevator button after you help him make his movie, but you can capture him anyway afterwards. You even get an achievement for this!
 * Before the Final Boss, you find the portrait holding poor Peach prisoner; this means, of course, that you have to use the Dark Light to break her out. However, if you purposely take your sweet time to do so, Mario starts pleading with you to hurry up. He really wants you to save Peach!
 * Wanted Poster: When the Big Bad's initial plan to nab Luigi fails, the Mooks start pasting Wanted Posters of Luigi everywhere in the hotel.
 * Warmup Boss: Steward is the first boss, and is hardly a threat to Luigi, being there mostly to show the player how to effectively use the Poltergust G-00.
 * Chambrea and Kruller too. Neither is dangerous, Chambrea's purpose being to show the player how to use the Suction Shot accessory, Kruller doing the same for Gooigi.
