Luigi's Mansion 3 is an upcoming third-person adventure game developed by Next Level Games for Nintendo Switch. The third entry in the Luigi's Mansion series, the game is scheduled to release sometime in late 2019.
Luigi has received an invitation to go on vacation in the Last Resort, a luxurious hotel. Naturally, he jumps at the opportunity and brings along his brother Mario, Princess Peach, and Professor E. Gadd's Toad assistants, with the Polterpup from the previous game tagging along as well. Unsurprisingly, it turns out to be a haunted hotel and a trap set by King Boo to capture Mario and company. With the help of E. Gadd, the new Poltergust G-00, and even Gooigi, Luigi must once again conquer his fears and rescue everyone. But it won't be easy...
After the mission-based structure of Dark Moon, this game returns 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 reach more floors, meeting a strange cast of ghosts along the way. The Poltergust G-00 gives Luigi several more tools to play with, such as Suction Shot plungers, and he can now summon Gooigi to reach new areas and provide extra firepower. The ScareScraper multiplayer mode returns from Dark Moon, now supporting up to eight players at once.
Tropes found in Luigi's Mansion 3 include:
- Advancing Boss of Doom: The E3 2019 trailer shows King Boo chasing our green-clad hero down a tight hallway, knocking down pillars of luggage in order to get closer to him.
- Artsy Beret: Morty, a Friendly Ghost first showcased in a Nintendo Treehouse video shown at E3 2019, works as a movie director and wears a black outfit with a beret. He takes his craft very seriously to the point that in the same Treehouse video, he sees "all the makings of a star" in Luigi and thus makes him star in a Kaiju film project.
- Artifact Title: Even more so than the previous game. While Dark Moon still took place in mansions, even if they weren't specifically Luigi's, this game neither takes place in a mansion nor is it Luigi's.
- Ascended Extra: Gooigi first appeared as the 2nd player in co-op mode in the Nintendo 3DS port of the original Luigi's Mansion. Here, he's a core game mechanic as explained by the narrator in the E3 2019 trailer.
- Banana Peel: While playing the E3 demo, if Luigi steps on a banana it will cause Luigi to slip and lose 1 health point.
- Bullfight Boss: The demo's boss fight is with a ghostly king you need to stun while he's charging to get a chance at destroying his armor.
- Clipped-Wing Angel: The boss fought in the Nintendo Treehouse video presentation is a basic ghost enemy wearing the top half of a monster suit. Luigi has to knock the monster suit off by propelling three energy balls into the ghost, and afterwards, it becomes a standard enemy that Luigi can defeat to end the fight.
- Distressed Dude: Mario is once again trapped inside a painting. This time, he's also joined by several Toads.
- Drives Like Crazy: In the E3 demo's opening cutscene, Red Toad drives the bus that's carrying Luigi and co. swerving all the way to the hotel, partly hitting the entrance gate, running over the curb and flooring a sign before stopping.
- Family-Friendly Firearms: In the E3 trailer, a police officer ghost digs around and finds a Splatoon-like water pistol and aims it like a real gun.
- Late-Arrival Spoiler: Luigi adopting the Polterpup was only revealed in the ending of Dark Moon, but this game made it obvious starting with the E3 2019 trailer.
- Lots of Luggage: The demo's opening cutscene shows Princess Peach bringing an enormous amount of bright pink luggage, rendering two Toads as Human Pack Mules as they carry towers of it into the hotel.
- Mouse Hole: A particularly large one is located inside the table within the dining room shown in the teaser trailer, directly under a wheel of Cartoon Cheese as noted above. You can even see ghost mice floating in and out of it.
- Notzilla: One boss fight of the game showcased by Nintendo Treehouse at E3 is a big homage to Kaiju films. Luigi meets a ghost film director named Morty who casts him in a giant monster movie... as one of the monsters, meaning that Luigi gets to fight a ghost wearing the top half of a Godzilla-like costume in the middle of a miniature city.
- Numbered Sequel: An interesting case, as the previous game didn't make use of this in North America.
- Production Foreshadowing:
- The Poltergust G-00 debuted in the reveal trailer for Simon and Richter Belmont in Super Smash Bros. Ultimate one month before the reveal trailer for this game. In the former trailer, Luigi fired one of his plungers at a Mummy. In the game proper, his front and back throw resembles the new Slam mechanic.
- Sequel Escalation: In previous games, King Boo concentrated on having Mario captured. This time, this extends to both Mario and Luigi's other friends as they can be seen trapped in paintings in the E3 trailer, and in a Freeze-Frame Bonus, you can see King Boo holding an empty portrait in front of a cowering, poltergust-less Luigi.
- Shout-Out: From the Nintendo Treehouse video...
- One of the posters on the movie-themed floor is of Little Mac. If you break it, some money will spill out as well as a green boxing glove resembling Little Mac's you can shoot out from the Poltergust.
- When Luigi and Gooigi are about to finish off the Notzilla for Morty's movie by blowing the fireball back at it, it looks like they're crossing the streams. Bonus points for also setting a giant monster on fire.
- Again on the movie-themed floor, Luigi encounters a stand-in for Samara.
- In the firefighter themed scenario, yet again on the movie-themed floor, there's a very familiar looking bicycle with a wrapped up blanket in a basket.
- Stylistic Suck: Also from the demo, one of Morty's horror movies features a Stringy-Haired Ghost Girl puppet... with a rubber duck on her head.
- This Looks Like a Job for Aquaman: The E3 trailer reveals that Gooigi's purpose is to pass through grates and spikes to access areas Luigi can't, but he can't take much punishment and dissolves instantly on contact with water. Therefore, you're going to need both to get through this campaign.
- The Unfought: The Nintendo Treehouse reveals that unlike the other boss ghosts, Morty is a "unique ghost" that doesn't fight Luigi despite the built-up suspense around getting his megaphone back and getting him to notice Luigi. Instead, the boss of his floor is the monster-suit ghost in his film, and he happily gives Luigi an elevator button once Luigi helps him finish his film (by defeating said monster-suit ghost).
- Verbal Backspace: The narrator of the E3 2019 trailer says of the hotel "You may never leave...ergh, want to leave."
- "Wanted!" Poster: Ever since the initial teaser trailer, posters of Luigi can be seen in the hallway corridors, along with a reward of a bag of gold under his head. As of the E3 trailer, the posters have been updated to show his full head and torso, as opposed to the comedically-sloppy photo which had his eyes cut off in the previous trailer.
