History VideoGame / LuigisMansion3

* TheLastOfTheseIsNotLikeTheOthers: E. Gadd states his laboratory is safe, sturdy and air-conditioned.

** You can zap the Toads with the flashlight.

''Luigi's Mansion 3'' is a third-person adventure game developed by Creator/NextLevelGames for UsefulNotes/NintendoSwitch. The third entry in the ''[[VideoGame/LuigisMansionSeries Luigi's Mansion]]'' series, the game released on October 31, 2019, on Halloween.

* AscendedExtra: Gooigi first appeared as the 2nd player in co-op mode in the UsefulNotes/Nintendo3DS port of the original ''VideoGame/LuigisMansion''. Here, he's a core game mechanic, required for many puzzles and boss fights.

* BitingTheHandHumor: Across the series, Professor E. Gadd creates a new Creator/{{Nintendo}} console-based device to contact Luigi. In [[VideoGame/LuigisMansion the first game]], it's the [[UsefulNotes/GameBoy Game Boy Horror]], and in [[VideoGame/LuigisMansionDarkMoon the sequel]], it's the [[UsefulNotes/NintendoDS Dual Scream]]. Those following the pattern would likely be expecting something like a DSI or UsefulNotes/Nintendo3DS, or maybe a jump to consoles with a UsefulNotes/WiiU gamepad. But in the third game, Professor E. Gadd's newest communication device is the "[[Platform/VirtualBoy Virtual Boo]]"! He plans on selling this on the market, predicting that [[ThisIsGoingToBeHuge it'll be a huge success]]. Anyone who knows their Nintendo history will no doubt be in hysterics over [[SelfDeprecation this little nod]] to one of Nintendo's most infamous failures.

Anyone who knows their Nintendo history will no doubt be in hysterics over [[SelfDeprecation this little nod]] to one of Nintendo's most infamous failures.

* ConsoleCameo: As in the previous two games, Gadd gives Luigi a Nintendo system to communicate with him. This time, it's the Virtual Boo, based on the UsefulNotes/VirtualBoy, complete with red and black graphics.

* SelfDeprecation: Professor E. Gadd [[ThisIsGoingToBeHuge talks highly about his newest invention]]: [[UsefulNotes/VirtualBoy The Virtual Boo]]. He tells Luigi about his plans to publicly market it and it'll "fly off the shelves". Anyone who knows about the history behind the console will see how heavily the irony is being coated on. Even the visual graphics when compared to the Game Boy Horror and the Dual Scream [[StylisticSuck are worse]].[[note]]The Game Boy Horror was capable of a full-quality video call between Luigi and E. Gadd, whilst the Virtual Boo's E. Gadd Hotline uses a low-res display with a very low framerate which makes the video communication look like pre-rendered sprites with only a red palette to work with.[[/note]]

** The [[UsefulNotes/VirtualBoy Virtual Boo]], in keeping with the SelfDeprecation, can only display red and black graphics and the video calls with E. Gadd are very low res and have an extremely choppy framerate.

** Polterkitty is normally the same size as Polterpup and looks like an ordinary spectral housecat, but when she's cornered, she suddenly transforms into a much larger, panther-like beast. From this, one may assume that [[spoiler:her owner, Hellen Gravely,]] also has a deceptive initial appearance...

* GhostlyGlide: Hellen Gravely wears a floor-length dress, and glides smoothly around the hotel. [[spoiler:As if the fact that she has purple skin and a [[NamesToRunAwayFromReallyFast name to run away from really fast]] weren't enough of a hint that she's a ghost!]]

* GogglesDoSomethingUnusual: As in ''Dark Moon'', one of the items you can find in the Scarescraper is the Dark-Light Goggles which lets you see otherwise invisible items at all times.
* GoldMakesEverythingShiny: In the prologue, the hotel initially appears to be this as befitting its luxury status with gold floors, gold walls, gold bathrooms and even gold furniture and as such, everything is ludicrously shiny. Naturally, it's all a trick and Luigi sees the illusion fade away as soon as he sets outside his room.

* GottaCatchThemAll: The game's main objective is capturing all boss ghosts (equivalent to the Portrait Ghosts in the first game) in order to retrieve the elevator's buttons, each taking you to a new floor. Each floor also has six hidden gemstones and one hidden Boo, the latter of which you can only find after beating the floor's boss. As before, you can also collect a ton of money. You don't buy upgrades to the Poltergust G-00 in this game, but you can buy extra lives as well as location devices for the Boos and gems until you've collected them all.

* ImprobableWeaponUser: The ghosts are able to pick up a variety of items to attack Luigi with including books, billiards cues, weights, etc.
* IncredibleShrinkingMan: One of the movie scenes in Paranormal Productions is based on this kind of plot, being a macro-scale work table with a box, bottle, and nails, coins, bills, and packing peanuts that dwarf Luigi. Topping it off is an animatronic spider inside the box which is giant at that size.

* ItsAllUpstairsFromHere: The hotel that is the game's setting, obviously, but Dr. Potter's floor in particular is specifically about climbing a huge flight of stairs to retrieve one of the elevator buttons[[spoiler:, after he grows a plant that takes it above]]. The game's path isn't entirely straight up the hotel (the fifth floor is visited second, and the sub-basement floor is visited twice later in the adventure), but the goal is to reach the top.

** In the Master Suite, you can uncover a model of Gloomy Manor in a glass case. Looking into it for a few seconds, a Golden Goob appears in your face.

* KnifeThrowingAct: There's a chest of blades and a knife wheel in the Twisted Suites. Vacuuming the wheel to spin it will see some blades throwing themselves into it with perfect accuracy, granting Luigi a gem.

* LastEpisodeThemeReprise: Clearing out a key room in the Master Suite also rewards you with the BGM changing to a variation of the title theme.

* MadLove: Hellen Gravely is deeply infatuated with King Boo. So much so that she broke him out of his containment and lured Luigi and friends to the Last Resort to trap them into paintings, all to impress King Boo. King Boo doesn’t seem to notice or care about her affections, and is only interested in her effectiveness in helping him catch Luigi.

* OutOfControlPopcorn: One of the collectibles is obtained in this way.

* PullARabbitOutOfMyHat: An unsurprising motif in the magic show-themed Twisted Suites. There are several stuffed rabbit dolls you can vacuum up for an achievement, and one of the magician bosses pulls one of the dolls out of her hat in a cutscene. There's also a topsy-turvy image that shows a magician from one angle, but a rabbit in a hat when vacuumed to flip it, and some purple Spirit Balls turn a key into a golden rabbit that you have to catch and revert to normal.

* ShiftingSandLand: Floor 10, the Tomb Suites. Its starting area is a very wide desert field whose main attraction is the pyramid located at the center. The boss is Serpci, who traps Luigi into the basement of the pyramid and the latter has to make his way back to confront her.

** You can capture [[FriendlyGhost Morty]] in his room, after he willingly gives you the elevator button. He's a completely optional capture, and deciding to go through with it gives you an achievement. What's more is that if you choose to catch him before he finishes editing the movie you helped him make (it gets finished after the first fight with Polterkitty), the movie will never get completed.

* WhatTheHellHero: If Luigi attempts to leave a room before freeing one of his friends from a painting, E. Gadd immediately express dismay that Luigi would even do such a thing.

* EscortMission: At one point, Red Toad goes missing in the Boilerworks with an important Poltergust upgrade, causing Luigi to go after him. Toad and the upgrade (which requires Toad to get) are actually recovered rather early, but because the normal entrance to the level becomes blocked by a sleeping Hammer, as well as the fact that the transporter directly back to the lab gets disabled ([[LampshadeHanging which E. Gadd quickly Lampshades if you try to use that]]), the player will be required to look for an alternate exit (that can only be accessed with Toad too, conveniently enough). This segment also introduces a specific type of Slinker that attempts to capture Toad, thus introducing the escorting aspect.

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 3 Toads, with the Polterpup from [[VideoGame/LuigisMansionDarkMoon the previous game]] tagging along as well. Unsurprisingly, it turns out to be a haunted hotel and a trap set by King Boo and the owner of the hotel, Hellen Gravely, to capture Mario and company. With the help of E. Gadd, the new Poltergust G-00, and even a slimy clone of him known as Gooigi, Luigi must once again conquer his fears and rescue everyone. But it won't be easy...

* FeedItABomb: Captain Fishook is defeated by rolling ignited gunpowder barrels into his mouth as his face slides across the possessed ship's deck.

* ForWantOfANail: King Boo and Hellen Gravely's plan are ultimately thwarted thanks to the presence of a ''laundry chute'' at the beginning of the game. Had it not been there, Luigi could not have escaped from their initial chase, found the Poltergust G-00, and proceeded to vacuum up every ghost in the hotel.

* MultipleEndings: Professor E. Gadd is rebuilding the hotel. And just like [[VideoGame/LuigisMansion the original game]], the scope of the hotel depends on how much money you collected throughout the game.
