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 on October 31, 2019. Unlike previous games in the series, the game takes place in a haunted hotel rather than an actual mansion. It is the third Luigi's Mansion game in the main series, being developed by Next Level Games, and the fifth game in the series overall.

Story
Luigi, Mario, Princess Peach, and various Toads are invited to a hotel called The Last Resort, which they travel to via a charter bus driven by Toad. Soon after Luigi and the gang arrive inside the first/second floor Grand Lobby during broad daylight and all check in at the front desk with the bellhop/receptionist ghost called Steward, they are then introduced and later escorted by the owner of the hotel, a mysterious purple ghost woman called Hellen Gravely, who is the one responsible for releasing King Boo, to take the elevator on the first floor within the Grand Lobby upstairs and the gang all stay on the RIP Suites fifth floor. Princess Peach is seen heading towards her respective hotel room (501), Mario to his (502), and finally Luigi departures into his own (503). Inside his hotel room 503, Luigi reads a novel whilst laying on a bed alongside Polterpup and quickly falls asleep, later having woken up on a rainy night accompanied with Princess Peach screaming now inside a haunted hotel with everyone but Luigi gone missing, having been trapped in paintings by Luigi's nemesis, King Boo. Luigi gets out of bed with simply a flashlight in hand and exits his RIP Suites fifth floor hotel room 503 and walks towards the floor's elevator only to later find Hellen Gravely walking out of the opened up elevator and shows Luigi the portraits where the remainder of the gang is trapped inside of with King Boo waiting right outside nearby in the hallway on the respective floor, who later chases Luigi through the hallway and can be seen attempting to trap Luigi inside a painting at the dead end of the hallway, though Luigi manages to escape by jumping into a laundry/garbage chute at the end of the hallway. After saving Professor Elvin Gadd from a painting and retrieving the Poltergust G-00, Luigi has save the rest of the gang, by navigating over seventeen stories (two below ground, fifteen above ground, and a roof) of the hotel in no particular order by collecting the elevator buttons from character-like boss ghosts at the end of every different themed floor. He also needs to defeat the ghosts with the help of Professor Elvin Gadd while inside Basement 1, using a new Poltergust called the Poltergust G-00 and a green doppelgänger called Gooigi. Once Luigi rescues Mario, Princess Peach, and the Toads from being trapped inside their respective paintings, they'll be waiting for Luigi at a place called the Safe Camp.

Gameplay
Luigi's Mansion 3 plays much like the two previous entries in the series, Luigi's Mansion and Luigi's Mansion: Dark Moon, allowing the player to re-explore already completed rooms and lacks missions respectively. The E3 2019 demo had a fifteen minute time limit. The Poltergust G-00 retains the basic qualities of the two previous vacuums, as well as the Strobulb item and the Dark-Light Device, though adds a targeting mechanism when blowing out items or a plunger. 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 a Burst. Luigi has a new device known as the Virtual Boo (VB), a parody of the Virtual Boy, which serves the same function as the Game Boy Horror and Dual Scream did from the two previous games. The money collected with the Poltergust G-00 can be used to buy Gold Bones (1,000 G), Boo Finder cartridges (1,000 G), Gem Finder cartridges (1,000 G), and also to buy hints from the Virtual Boo's E. Gadd Hotline while in the Lab inside Basement 1 to find in-game floor themed collectible gemstones and other various puzzles, which when brought will activate the HD Rumble in the Joy-Cons when getting close to a gemstone or Boo while in certain rooms on floors, which can also be felt when using the Poltergust G-00. Professor E. Gadd will sometimes suggest Luigi to come to his Lab in Basement 1 to buy hints from him to solve the floor's puzzles and such whenever the player is struggling, though hints can be turned off in the Guide/Settings menu. There are six floor themed gemstones and six Boos on each floor. The game automatically saves progress whenever entering a room or elevator. There are in-game achievements for certain objectives. Story mode (co-op), ScareScraper (co-op), and ScreamPark can't be played in co-op multiplayer on the Nintendo Switch Lite without detached official Nintendo Switch Joy-Cons. There's a brightness slider to control the hue of a given area from darker to lighter in the game's Settings. Story mode can be beaten in roughly four hours.

Gooigi, introduced in the Nintendo 3DS remake of the first Luigi's Mansion, reappears and is stored in the Poltergust G-00, hence Gooigi. Gooigi has up to 25 HP, while Luigi has over 99 HP, and 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, causing an immediate Game Over. The Game Over screen showcases King Boo having Luigi, Mario, Professor E. Gadd, Princess Peach, and the two Toads trapped inside paintings and ends saying, "Good Night!". Luigi and Gooigi cannot be controlled at the same time in single-player mode, but Gooigi can be controlled by a second player with the second Joy-Con (R) controller for co-op multiplayer. If Luigi attempts to enter a door with Gooigi out, Gooigi will automatically retract into the Poltergust G-00.

ScareScraper
Like its direct predecessor, ScareScraper also returns, allowing for up to eight-player co-op multiplayer (via four Luigis and four Gooigis)   to clear either 5, 10, or a random amount of floors with a five minute time limit for each floor, except the roof, which has a time limit over seven minutes. The mode also features procedurally generated floors, with different challenges on each floor such as Capture the Ghosts!, Find the Toads!, and Collect the Money!. It acts very similar to its prequel appearance, though adds new abilities and functions such as the super suction, super strobe, a red siren trapdoor detector helmet, voice chat, and the Blackout. Boolossus awaits the Luigis and Gooigis at the top of the ScareScraper hotel roof upon completing all the set floors. ScareScraper is more challenging than story mode, however.

ScreamPark
A multiplayer party mode where two teams called Team Luigi and Team Gooigi consisting of Luigis and Gooigis respectively, set to compete against each other on different levels with a two minute time limit where they have to capture the most Goopers (Ghost Hunt), collect the most coins while riding floaties in a indoor swimming pool (Coin Float), and manage to avoid hitting a wooden castle pellet trap and smash the most bullseye targets on the ends of a rotating wooden pirate wheel to win (Cannon Barrage).

Nintendo website description
''Luigi’s dream vacation turns into a ghostly—and gooey— nightmare! Luigi embarks on a dream vacation with Mario and friends upon receiving an invitation to a luxurious hotel. However, his dream quickly becomes a nightmare when King Boo reveals everything had been a ploy to capture Mario and friends. With the assistance of Professor E. Gadd once again, the reluctant and cowardly hero Luigi traverses up and down treacherous floors of the now-ominous hotel on a quest to save them. Wield the upgraded Poltergust G-00 to slam and blow away the ghosts’ defenses, or summon Gooigi, an all-green doppelganger that can help Luigi overcome obstacles he can’t get past alone. Interchange between Luigi and Gooigi as one player, or grab a friend and control one each. For more frenetic multiplayer action, race the timer to clear various objectives on a series of floors in ScareScraper mode. ScareScraper mode can be played online* or locally with up to eight players on four Nintendo Switch systems (additional games required; sold separately).''

Pre-release and unused content
The game was originally going to be a Wii U title, though development started for Nintendo's next generation console in earnest following the completion of Next Level Games' Metroid Prime: Federation Force. The Slam and Burst moves were planned during the Wii U prototype. Prior to his debut appearance in the Nintendo 3DS remake of Luigi's Mansion, Gooigi was already planned for Luigi's Mansion 3 upon the Nintendo Switch's launch when the developers got the inspiration from the Joy-Con for multiplayer mode. While in development for the Nintendo Switch, Luigi's Mansion 3 was originally a tentative title prior to becoming the final name.

In an interview, producer Kensuke Tanabe mentioned that the developers had experimented with including a warp system where the player could turn on TV sets found in the rooms and warp between them to travel throughout the entire hotel, much like the Paranormal Productions eighth floor. However, as it was not possible to include a TV in every room, the idea of using this mechanic throughout the entire hotel was scrapped in favor of the elevator idea.

The Grand Lobby first floor originally had rectangular shaped pictures of Luigi, Mario, Toad, and Princess Peach hanging from the ceiling, a clock behind the front desk on the left with a key infront of it, a bland different wall design above the front desk, and two big wall paintings on the second floor behind the front desk area.

The Mezzanine second floor dining room had different table clothes with no table lamps on top and there wasn't a lobster or ice cream inside a white ceramic pedestal dish in the back wall table.

The Hotel Shops third floor indoor shopping mall's gift shop had a different interior design compared to the final version, as well as no stacked chairs or a janitors cart infront of it either.

The Great Stage fourth floor theater hallway had no Boo design on the wall on top of the Mad Piano painting, but a later version does.

While Luigi is reading a novel on the bed in his RIP Suites fifth floor hotel room (503) and quickly falls asleep, he didn't drop the book exactly in-between his lower stomach center area, nor had "Zzz" coming out of him while snoring either. Mario's hotel room 502 was different looking, lacking fog, had the purple comfy chair was closer to the table near the bed with two pizza boxes on top, there was another purple comfy chair to the right of the table closest to Mario's bed, there were four pizza boxes on top of a mobile serving table, the chair in the back left was tipped over, Mario's suitcase with his signature emblem on it wasn't opened up, the table nearest to Mario's mattress had food that was tipped over, and such.

The Castle MacFrights sixth floor had dark and light stones on the back wall in the inner area infront of the wooden floorboards between both the rock and wooden stairs.

The Garden Suites seventh floor originally had a room with a large watermelon with three smaller watermelons besides it, though just four smaller watermelons in the final version. One of the Garden Suites seventh floor bedroom had a different appearance with grass and less vines. The eighth floor elevator button on the Garden Suites seventh floor was originally to be collected by having Luigi water a plant that sprouts a beanstalk, which had to be climbed to reach the eighth floor elevator button on the tree's purple leaf, with the final version requiring Luigi and Gooigi to use the Poltergust G-00 to get to the top of the tree and suck on a venus flytrap's mouth open.

The Paranormal Productions eighth floor had the golden velvet rope barriers infront of a snow mountain prop near the elevator protruding out just slightly and had ceilings lights on the theater poster-like display hallway area. The Fire Set (Studio 3) room didn't have purple cat ghosts, just a Hammer and Goopers.

The Dance Hall fourteenth floor originally had green/blue colored three way subwoofer loudspeakers.

The exterior of the ScareScraper hotel originally didn't have translucent windows.

Hellen Gravely

 * "Guests! Welcome to The Last Resort! My name is Hellen Gravely, and I am the owner of this hotel. I am absolutely delighted that you decided to accept my invitation."
 * "Well well well! If it isn't my MOST esteemed VIP! I was just on my way to see you... Is your living room your expectations? Doesn't it SCREAM good taste? [...] Oh, I can barely contain myself. You have no idea how much I wanted you to except my invitation! "Why is that?" I'm sure you're wondering. ha ha ha... you see... There is someone I truly adore! He is the inspiration of some of my greatest ideas... Like inviting you here! I'm such a huge fan of his! That's why it's so wonderful that I get to introduce him to... YOU! That's right, Luigi! I hope you're ready!"

Hotel Staff

 * "Is something the matter? I hope nothing is making your stay here less than perfect... Our entire staff is devoted to providing you with the ideal vacation experience! Heh heh heh..."

King Boo

 * "Mwah ha ha!" Surprise, Luigi! It's-a me, King boo! That old coot had me tight in his lab... But guess what? I GOT OUT! The Hotel owner was here just dying to meet me, so she busted me out. Pretty lucky, huh? Anyway, I didn't think you you'd actually show up here. I was ready though, just in case. In fact, vengeance is nearly complete! What do I mean by "vengeance"? Glad you asked! I'm trapping you and everyone in your vacation party... in frames! Awww, there there, Luigi. It'll be over soon. It's time for a family reunion! BOO-YA! [...] Mwah ha ha! Take THAT! Oh, and there's one more frame, of course. I saved it especially for you! Stay right there and put on your best terrified face, Luigi! This is game over!"

Luigi

 * "Oh, yeah!"
 * "Wowie zowie!"
 * "Uh, bye."
 * "OK."
 * "Night, night."
 * "Hello?"
 * "Oh no!"
 * "Mario?"
 * "M-Mario?"

Mario

 * "Let's go!"
 * "Oh, here I go!"
 * "Yeah!"
 * "Bye, bye!"
 * "Night, night!"
 * "Oh... Doggy!" (when Polterpup steals his piece of cake)

Princess Peach

 * "This hotel is so big, Luigi! It's gorgeously decorated too! We're so lucky to have gotten an invitation to come here! Hee hee!"
 * "Aaaaaahhhhhh!!!"

Professor E. Gadd

 * "Heh Heh Heh! Welcome to my lab!"
 * "Regardless! To find ghosts and your friends, you'll need to explore this hotel! To help you out, I'll give you one of my greatest inventions yet! I call it...the Virtual Boo! VB for short! It's a state-of-the-art virtual-reality device fitted with a fancy red screen! Really cutting-edge stuff! And red is all the rage, you know? Just wait until I finish the marketing materials on this! It'll fly off the shelves! Heh heh heh! You can use the VB to communicate with me at any time."
 * "Stop fooling around, Luigi! Go to my room and get my briefcase! If you get turned around, you can always check the map using the VB..."
 * "Oh, Luigi! You're finally back, eh? You shouldn't keep an old man waiting, y'know. Professor E. Gadd's Shopping Network is now open for buisness right here in the lab! Ta-daaaa! I've stocked some rather useful items. They're all yours...for a modest fee! Heh heh heh!"
 * "By the way, Luigi, here's a fun bit of trivia for you: every time you go through a door, all of your progress up to that point is saved. Automatically! But it might..."
 * "Press to fire the Suction Shot, and take away his shield!"
 * "Let's go, boy! What did we see during your last training? Press while sucking, what does it tell you? That would allow you to switch between Gooigi and you. If one of you was sucking something, you will continue to do it! So you could suck, even blow, all the duets at the same time!"
 * "Luigi, look! That must be the megaphone! Looks like it's trapped in some spiderwebs! Those must be hearty webs..."

Polterpup

 * "Woooof? (Comfortable with what you learned?)"

Steward

 * "Welcome, guests, to The Last Resort! Are you ready to check in?"

Morty

 * "The tragedy. Oooooh ho ho ho! Is this my end? Is this what I, Morty, director of the finest films, am destined for? How could I lose it... I am a puny, worthless movie director... That's all... Even the sparkle from this beautiful button is now nothing but a dull hue... AHHHHH! My bright red megaphone! Where art thou?! I would give anything to be able to hold my dear, sweet megaphone again... YOU! Wait a second! Hold it right there! I didn't notice until now, but your face... You have some nice features! And your build... Not bad. Not bad at all! I see all the makings of a star! Ahhh. My creativity is shaking off all the dust and surging to life! Come, come! Let's start shooting! Where's my crew?! Places, everyone! Take your places! And...action! Excellent! Excellent! Keep it up! Excellent work, you two! My gut tells me this is going to be a masterpiece! Now is your chance to achieve stardom! Now this... Oooh THIS is art... Cut!"

Toads

 * "Yahoo! Whoops!"
 * "Hhhhrrrrgggg! Princess Peach definitely didn't forget to pack anything... Ah, Luigi! What's up? Ahhhhh! Oh no!"
 * "My head's stuck! I can't get out!"

References to other games

 * Donkey Kong: On the Garden Suites seventh floor, Dr. Potter waters a plant that sprouts and then blasts out pineapples that bounce down the stairway, which Luigi and Gooigi have to dodge to the best of their ability, much like how Mario had to dodge the barrels rolling down the steel beam platforms being thrown by Donkey Kong.
 * Mario Bros. (Game & Watch): The pizza boxes in the RIP Suites fifth floor in Mario's room (502) and the Paranormal Productions eighth floor say "Since 1983," referencing Luigi's debut appearance in this game.
 * Super Mario Bros.: Upon arriving at The Last Resort's Grand Lobby first floor, the room theme sounds similar during the intro portion.
 * Super Mario 64: There are posters on the wall in The Great Stage fourth floor music theater area on the featuring various instruments with an angry expression, one of which being a painting of an angry piano.
 * Luigi's Mansion: There is a indoor shopping mall area on the Hotel Shops third floor with stores themed after the four suits of a deck of cards consisting of a club, heart, diamond, and spade based on the four respective Area floor keys. Chauncey's boss theme plays when using the Suction Shot on a crate in ScareScraper. The three blue beta ghosts from the Nintendo Space World 2000 trailer are referenced in the Mezzanine second floor kitchen area. Professor E. Gadd's voice is sampled and his mouth is synchronized to speak in his usual gibberish voice.
 * Super Mario Sunshine: The Coins make a similar sound effect when collected like in this game. Mario is distracted by cake during the intro in the Grand Lobby first floor, later pizza in his RIP Suites fifth floor hotel room 502, much like when he was distracted and daydreaming about seafood while watching TV on the airplane in the intro.
 * Mario Strikers Charged: In one of the hallways in the theater on the Paranormal Productions eighth floor, a framed poster of Mario performing his Mega Strike move can be seen and another framed poster showing a bunch of characters running together from an aerial view.
 * Mario Kart Wii: When Luigi wakes up by Princess Peach's, "AAAAAHHH!!!" during a rainy night while sleeping inside his RIP Suites fifth floor hotel room 503, this is a reused sound effect when she gets hit by a Spiny Shell or falling into water.
 * Punch-Out!! (Wii): In one of the hallways in the theater on the Paranormal Productions eighth floor, a framed poster of Little Mac in his victory pose with Doc Louis and Sandman in the background can be seen. Using Suction Shot on the poster will cause one of Little Mac's green boxing gloves to come flying out. Two of Little Mac's gloves can also be seen lying on the floor within a gym room on an unknown floor, supposedly having been worn by a Hammer ghost.
 * Super Mario All-Stars Limited Edition: A gym room on an unknown floor has a parallel curved golden leaf design on the top wall above the horizontal wall mirror seen on Princess Peach's press letter.
 * Luigi's Mansion: Dark Moon: In one of the hallways in the theater on the Paranormal Productions eighth floor, a framed poster of Luigi pointing the Poltergust 5000 towards King Boo is seen. A painting inside a bathroom on the Mezzanine second floor, the RIP Suites fifth floor hallway, The Spectral Catch thirteenth floor pirate ship room, and some sections of certain floors in the ScareScraper shows the Gloomy Manor. The same music is played when sucking a ghost with the Poltergust G-00. Polterpup returns, though lacks pupils, and serves as the tutorial guide for the first few floors. The ScareScraper mode also returns. Once Luigi completes the Garden Suites seventh floor, the same room clear theme plays.
