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 they arrive inside the first/second floor Lobby during broad daylight and all check in at the front desk with the bellhop/receptionist ghost, they are then escorted by a mysterious purple ghost woman to take the elevator on the second floor within the Lobby upstairs and the gang all stay on the fifth floor. Inside his hotel room, Luigi reads a novel whilst laying on a bed and quickly falls asleep alongside Polterpup, later having woken up inside a haunted hotel during midnight 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 fifth floor hotel room only to later find King Boo in the hallway on the respective floor attempting to suck Luigi into a painting. To save the rest of the gang, Luigi has to navigate 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 the Basement (B1), using a new Poltergust called the Poltergust G-00. 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, a parody of the Virtual Boy, which serves the same function as the Game Boy Horror and Dual Scream from the two previous games. The money collected with the Poltergust G-00 can be used to buy Gold Bones and also to buy hints from the Virtual Boo's E. Gadd Hotline to find in-game floor themed collectible gemstones and other various puzzles. There are in-game achievements. The HD Rumble can be felt through the Joy-Con while using the Poltergust G-00.

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, 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 eight-player co-op multiplayer (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. 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. Somebody awaits the Luigis and Gooigis at the top of the ScareScraper hotel 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 Googis respectively set to compete against each other on different levels with a two minute time limit where they have to capture the most Goopers, collect the most coins while riding floaties in a swimming pool, and manage to avoid hitting a wooden castle and smash the most targets on a wooden pirate wheel ends to win.

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 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 theater area on an unknown floor had no Boo on the wall on top of the Mad Piano painting, but a later version does.

The sixth floor Mezzanine dining room had different table clothes with no table lamps on top and there wasn't a lobster or ice cream fudge on plates in the back wall table.

Professor E. Gadd

 * "Heh Heh Heh! Welcome to my lab!"
 * "Press to fire the Suction Shot, and take away his shield!"
 * "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?)"

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!"

 * Donkey Kong: On the 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 dodged the barrels rolling down the steel beams thrown by Donkey Kong.
 * Mario Bros. (Game & Watch): The pizza boxes in the fifth floor trashed room and the eighth floor say "Since 1983," referencing Luigi's debut appearance in this game.
 * Super Mario Bros.: Upon defeating Dr. Potter on the seventh floor, there's a plant that can be watered and sprouts to a Beanstalk to reach the eighth elevator button, which is stuck on one of the tree's giant purple leaves.
 * Super Mario 64: There is a poster on the wall in a music theater area on the fifth floor with a painting of an angry piano.
 * Luigi's Mansion: There is a indoor shopping mall area on the fifth 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.
 * Super Mario Sunshine: The Coins make a similar sound effect when collected like in this game.
 * Mario Strikers Charged: In one of the hallways in the theater on the 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.
 * Punch-Out!! (Wii): In one of the hallways in the theater on the 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 a green boxing glove similar to Little Mac's to come flying out.
 * Luigi's Mansion: Dark Moon: In one of the hallways in the theater on the eighth floor, a framed poster of Luigi pointing the Poltergust 5000 towards King Boo is seen. A painting inside a bathroom 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. The ScareScraper mode also returns. Once Luigi completes the seventh floor, the same room clear theme plays.
