Luigi's Mansion

Luigi's Mansion is a launch title for the Nintendo GameCube, released in September 2001. It marks the second time where Luigi is the main character, with Mario playing a supporting role, the first being Mario is Missing! for the SNES, and Professor E. Gadd and King Boo are also introduced in this game. A sequel to this game known as Luigi's Mansion: Dark Moon was released for the Nintendo 3DS in 2013.

Instruction Booklet

 * And the grand prize is a big, haunted mansion!?

One day, Luigi received an unexpected message: You've won a huge mansion! Naturally, He [sic] got very excited and called his brother, Mario. "Mario? It's me, Luigi. I won myself a big mansion! Meet me there and we'll celebrate, what do you say?" Luigi tried to follow the map to his new mansion, but the night was dark, and he became hopelessly lost in an eerie forest along the way. Finally, he came upon a gloomy mansion on the edge of the woods. According to the map, this mansion seemed to be the one Luigi was looking for. As soon as Luigi set foot in the mansion, he started to feel nervous. Mario, who should have arrived first, was nowhere to be seen. Not only that, but there were ghosts in the mansion! Suddenly, a ghost lunged at Luigi! "Mario! Help meee!" That's when a strange old man with a vacuum cleaner on his back appeared out of nowhere! This strange fellow managed to rescue Luigi from the ghosts, then the two of them escaped... It just so happened that the old man, Professor Elvin Gadd, who lived near the house, was researching his favorite subject, ghosts. Luigi told Professor E. Gadd that his brother Mario was missing, so the Professor decided to give Luigi two inventions that would help him search for his brother. Luigi's not exactly known for his bravery. Can he get rid of all the prank-loving ghosts and find Mario?

Area 1
Luigi, having won a mansion in a contest he did not participate, enters Boo Woods and locates it. He enters the mansion and is soon attacked by a ghost, but Professor E. Gadd appears and fights off the ghosts with a vacuum. He tells Luigi that the mansion has appeared out of thin air and is an illusion, and that Mario is captured by King Boo and his minions. He gives Luigi the Poltergust 3000, to vacuum up ghosts, and the Game Boy Horror to communicate with E. Gadd, scan objects, and see a map of the mansion.

Luigi enters the mansion, sucking up ghosts and finding keys, while meeting Toad along the way, until he encounters a portrait ghost, Neville. He defeats him, sucking him into the Poltergust 3000. He does the same to Lydia, Neville's wife, and fights their baby, Chauncey, who sucks Luigi into his crib and fights him as a giant ghost, but is defeated and sucked into the Poltergust 3000, which begins to get full, so Luigi returns to E. Gadd's lab and empties the Poltergust 3000, turning Neville, Lydia, and Chauncey back into portraits.

Area 2
Luigi enters Area 2, another area through a previously blocked door and fights more ghosts. After defeating the Floating Whirlindas, he enters the Storage Room and hits a switch, which opens a trapdoor where 50 Boos and their leader, King Boo, are hiding. All of them escape, flying into different rooms of the mansion. Luigi returns to E. Gadd's lab and E. Gadd tells him that the Boos were the ones who released the portrait ghosts, and Luigi must capture the Boos to weaken their power, as they are stronger in greater numbers. So Luigi goes through the many rooms of the mansion, vacuuming up any Boos he sees. He also meets Madame Clairvoya, a fortune teller ghost, who tells him to bring her any of Mario's items he finds lying around in the mansion so she can get details on his whereabouts. The items are: Mario's hat, Mario's glove, Mario's shoe, Mario's letter, and Mario's star. After sucking up Shivers the butler, Melody Pianissima, Mr. Luggs, and Spooky the dog, Luigi enters the Cemetery and fights the shadowy ghost, Bogmire. He defeats him and sucks him into the Poltergust, which he then empties at E. Gadd's lab to turn all the Portrait Ghosts into portraits.

Area 3
Luigi enters a third area into the courtyard. Down the well, he sees into King Boo's altar, and discovers that King Boo has imprisoned Mario in a portrait. He goes through new rooms of the mansion, finding Mario's items and vacuuming up ghosts, including portrait ghosts Biff Atlas, Miss Petunia, Nana, Slim Bankshot, and twins Henry and Orville. After Luigi brings Madame Clairvoya enough of Mario's items, she tells him that she sees Bowser in a vision, which is shocking because Mario defeated Bowser, and she suspects that King Boo revived him. With her job done, she tells Luigi to suck her into the Poltergust so she can return peacefully to her portrait. After he does so, and defeats enough Boos, he enters the balcony and fights Boolossus, a big Boo made up of 15 Boos. He throws him into a spiky statue to split him into the 15 Boos and sucks them all into the Poltergust. He then empties the Poltergust at E. Gadd's lab to turn all the portrait ghosts, including Boolossus, into portraits.

Area 4
When Luigi enters Area 4 in the attic, the mansion is suddenly struck by lightning and it goes dark. He then goes to the breaker room to turn the power back on, but finds it locked. Luigi looks for the key and soon encounters a ghost named Uncle Grimmly and defeats him to get the key. After he turns the power back on, he catches more Boos and portrait ghosts, including the Clockwork Soldiers, Sue Pea, Jarvis, and Sir Weston, before entering the room of Vincent Van Gore, one of the most prominent portrait ghosts who is painting regular ghosts. He sends several waves of ghosts after Luigi, but Luigi defeats them all, causing Van Gore to go into a state of depression, and Luigi sucks him into the Poltergust without much resistance. He then goes to the Secret Altar down a creepy hallway in the basement and encounters King Boo, who reveals that he was the one who told Luigi that he won the mansion in a contest, and set it up as revenge for all the trouble they caused him (though they may not have met him before, they have been fighting against Boos for years, plus King Boo works for Bowser). King Boo goes into Mario's portrait (which turns into a Bowser portrait) and sucks Luigi into it. In an arena resembling the roof of the mansion with fire for a background, Luigi fights Bowser (as Madame Clairvoya had seen), but when he hits him in the head with a bomb, it is revealed to be King Boo inside a False Bowser. Luigi defeats King Boo while avoiding Bowser's head and sucks him into the Poltergust.

Luigi returns to the lab and turns all the portrait ghosts, including King Boo, into portraits again. E. Gadd then reverses the Portrificationizer to release Mario from his portrait. After Mario goes through a reverse-procedure of all the portrait-ghosts captured, he rockets out of the machine, colliding with Luigi, but being otherwise alright. Luigi laughs and cries with happiness that his brother is safe. Since King Boo has been defeated his illusion of a mansion fades away, though the money and jewels Luigi collected in the mansion was real, and with it he gets a new mansion or house. But if Luigi gets H rank, he ends up with only a tent.

Gameplay
Luigi uses two devices given to him by E. Gadd to progress through the game: the Poltergust 3000 to suck up ghosts, and the Game Boy Horror (which is designed to resemble a Game Boy Color) to investigate objects, navigate the mansion and communicate with E. Gadd. On top of its primary function, the Poltergust has various other uses as well, such as sucking up money and being used as a flashlight to help Luigi see and even stun ghosts. Once Luigi collects the corresponding Elemental Medal, he can also use the Poltergust to suck up Elemental Ghosts and expel their fire, water or ice powers to fight other ghosts and deplete their HPs so that Luigi can capture them. In turn, Luigi's own HP is lowered whenever he takes damage and requires him to replenish it by collecting Hearts, or risk a Game Over (at which point he collapses and the word "Goodnight" appears overhead).

Portrait Ghosts
In his exploits, Luigi captures up to twenty-three gallery ghosts (five are optional). These ghosts (excluding the third and the final/fourth boss) have 100 HP, but their hearts are not automatically shown like other ghosts: Luigi must find each ghost's weakness before he can suck them up. The following are listed in order of appearance appear in the game:

Area Two
Note: Although Luigi first meets Madame Clairvoya in Area Two, he captures her after he begins Area Three.

The Boos


There are fifty one (including King Boo) Boos that hide in the various rooms of the mansion. Thirty-five of these are named to differentiate between them, and the remaining fifteen make up the third Boss of the game, Boolossus. The magic of the King Boo's spells increase based on the number of his minions nearby. Because of this, Luigi needed to capture twenty Boos to break the seal designed to block Boolossus from him. After capturing twenty more, the seal separating Luigi from King Boo was broken. If Luigi catches all fifty Boos, he will be rewarded with the extremely valuable Gold Diamond. Each of the Boos' names are puns. For example, "Booigi" is a pun on "Luigi" and "Game Boo" is a nod to the Game Boy.

Other Ghosts

 * Bogmire Shadow
 * Fire Elemental Ghost
 * Ice Elemental Ghost
 * Trapdoor
 * Water Elemental Ghost

Luigi's New Mansion
Similar to the mechanics of Wario Land: Super Mario Land 3, all of the money and treasure Luigi collects in his adventure is used to build a new mansion in place of the old one. The more money he collects from treasure rooms, watering plants, catching Portrait Ghosts and examining furniture, the better the mansion will be (it will be a large / small house in the lower ranks). The house will become a painting at the front of the Gallery, with Luigi's total money on the bottom-left corner. The message will be "Welcome to Luigi's NEW Mansion!" unless Luigi achieved Rank A or H. The requirement to achieve Rank A was increased significantly during localization for PAL regions, hence the two values given for Rank A and Rank B.


 * Rank A: Finish the game at or above 100,000,000G or 150,000,000G(PAL). + Message: Congratulations! Your mansion is complete!
 * Rank B: Finish the game with 70,000,000 to 99,999,999G or 70,000,000 to 150,000,000G.
 * Rank C: Finish the game with 60,000,000 to 69,999,999G.
 * Rank D: Finish the game with 50,000,000 to 59,999,999G.
 * Rank E: Finish the game with 40,000,000 to 49,999,999G.
 * Rank F: Finish the game with 20,000,000 to 39,999,999G.
 * Rank G: Finish the game with 5,000,000 to 19,999,999G.
 * Rank H: Finish the game with 5,000 to 4,999,999G. + Message: The haunted mansion disappeared without a trace...

Although it may seem to be a feat to achieve Rank A, it may be considered even more difficult to achieve Rank H, as Luigi will usually collect more than 5,000,000G without actively trying to get money. Thus, Luigi must work to avoid money if they want to achieve rank H.

The Rank A Mansion appears at the side of Luigi Circuit in Mario Kart: Double Dash!!. However, Rank D is shown in the opening of the sequel, Luigi's Mansion: Dark Moon.

Hidden Mansion
Once the player beats the game once, the quest retried in the normal mansion or the "Hidden Mansion". It is the same gameplay, except for two things: a) Ghosts (including Boos) give double the damage to Luigi, b) The Poltergust 3000 has 1.5 times more power. This can help get more pearls, which means more money and nicer frames.

Mario's items
Luigi may find several items that Mario has dropped in the mansion. Once he has received one, he can show it to Madame Clairvoya for information of Mario's whereabouts.

Miscellaneous items

 * Hearts
 * Poison Mushrooms
 * Keys
 * Cheese
 * Elemental Medal
 * King Boo's Crown

Professor E. Gadd's Gallery
Professor E. Gadd had trapped the Portrait Ghosts into paintings during his past ghost adventures and put them for display in his personal gallery - until King Boo released each of them. As Luigi recaptures gallery ghosts, they will be framed in three colors: bronze, silver, or gold. The color depends on how much HP (out of 100 for each non-boss gallery ghost) Luigi sucks in one go, which produce pearls:


 * Bronze. Only small pearls, which Luigi earns one for every 10 HP sucked at once. This frame is also the only frame that Luigi can get if he has less than 50 HP while capturing the portrait ghost.  The portrait ghost itself is poor in quality.
 * Silver. At least one medium pearl, which the ghost gives up for every 50 HP sucked and every 10 after. So for 60, 70, and 80 HP at once, Luigi earns another medium pearl. If Luigi has 50-89 HP, this is the best quality portrait that he can get while capturing the portrait ghost. The portrait ghost is shown in better quality.
 * Gold. The only big pearl possible is given up if Luigi can suck 90 HP in one turn. Luigi also needs to have 90 HP or better to get this frame.  The quality of the portrait ghost is most often just what it looked like when Luigi captured it.

If Luigi sucks all 100 HP at once, no extra pearl is awarded. The maximum amount of money to be gained per Portrait Ghost is 1,600,000G: 4 small pearls, 4 medium pearls, and 1 big pearl.

Boss gallery ghosts' (Chauncey, Bogmire, Boolossus, and King Boo) frames and quality are determined by how high Luigi's health is after capturing the ghost.


 * Bronze. If Luigi fails to keep his health at 60 HP, he will get this painting.
 * Silver. To get this portrait, Luigi's health must be kept above 60 HP at the end of the battle.
 * Gold. To obtain this high-quality painting, his health must not have declined below 90 HP at the end of the battle.

PAL Differences
The PAL version of Luigi's Mansion (Europe and Australia) increased the number of changes for the Hidden Mansion:


 * The PAL Hidden Mansion is mirrored from left to right when compared to the Normal Mansion. The NTSC version keeps the layout the same.
 * There are more normal ghosts around the mansion.
 * Bosses are more difficult, having different attacks. (Chauncey's rocking horses, for example, are much bigger, and swerve left to right instead of going straight). A major change in the Boolossus battle is that the player rides around on the vacuum cleaner while trying to pop Boolossus, making movement more slippery.
 * Rooms are much darker in the PAL version; this, however, is only as dark as in the NTSC version of both mansions, the normal PAL mansion being lighter.
 * Most Boos have more HP in the PAL version, although some have less.
 * Fewer hearts. Locations that have hearts in the Normal Mansion do not have them. Hearts that heal 50 HP exist in the Courtyard by vacuuming the Slim Bankshot-like statue.
 * Speedy Spirits and Gold Mice always give up a Silver Diamond when caught, raising the maximum possible amount of money from 142,390,000G to 186,440,000G . Since the requirement to achieve a Rank A mansion in PAL regions is higher than the amount of money in the normal mansion, it is necessary to play through the hidden mansion to receive Rank A in those regions.
 * 45 rather than 40 Boos are required to fight the final boss.
 * Boos are, in general, more agile and difficult to catch.
 * Five ghosts rather than three fight Luigi in The Artist's Studio.

These changes were made after American and Japanese gamers complained that the Hidden Mansion offered virtually no changes. Shigeru Miyamoto himself thought up some things to add to the PAL version's Hidden Mansion. Most of the changes made seem to make the PAL version harder than the NTSC version.

Luigi

 * "MARIO!/MARIOOO?/Mario?/M-M-M-M-Mario?"
 * "What a dreadful picture... But that candle next to it might be important..."
 * "I'm willing to bet there's something cold in here."
 * "It's a picture, but I wouldn't call it art."

Mario

 * "Get me outta here!"
 * "Ey, Luigi, What's the hold-up?"

Professor E. Gadd

 * "I'm getting too old for this ghost-catching tomfoolery."
 * "I swear, this house seems to have more and more ghosts every day!"
 * "Alright, youngster! Look lively! Follow me, posthaste!"

King Boo

 * "I don't plan to give up my favorite decoration. I like Mario where he is."

Beta elements
Luigi's Mansion was originally just a tech demo for the N64, but Nintendo turned it into an entire game for the GameCube. The mansion was slightly shorter, along with no chimneys. The Poltergust 3000 had a heat meter, and if it got too hot it would explode and damage Luigi. It was said that Luigi's Mansion  was going to be rated "T" instead of "E".

Staff
The game's producers were Shigeru Miyamoto and Takashi Tezuka, and the director of the game was Hideki Konno.

Other media
Luigi's Mansion appears in volume 26 and 29 of Super Mario-Kun. In volume 26, which usually follows the story of Paper Mario, the Luigi's Mansion section is condensed into one chapter. The story begins similarly to the game: Luigi wins a mansion. He tries calling Mario's name, but Mario is absent. Luigi then treks to the mansion by himself. After a walk through the forest at night, Luigi is horrified to see his mansion. There, he meets a harmless Boo (案内役 テレサ) that leads him into the mansion. Inside the mansion, he and the Boo find a vacuum, so he tests it on the Boo, much to the Boo's anger. Luigi proceeds to vacuum the ghosts, and he even encounters a Shy Guy Ghost, which he doodles on its face.

Luigi then finds Mario trapped in a painting. Luigi is then ambushed by Bowser. Luigi attempts to run behind Bowser, but Bowser twists his head and burns Luigi. While Bowser throws a spike ball, Luigi uses his vacuum to deflect it at him, knocking off the head. King Boo flies out, and Luigi proceeds to suck in King Boo, breaking the spell and freeing Mario. The Bowser head, still flying, lands on Luigi's head, and Mario, mistakening him for Bowser, fights him. Once Mario realizes his mistake, he immediately regrets what he done, and the Boo watches them. Despite the chapter's being seemingly disjointed, Luigi later joins Mario during a fight with Huff N. Puff and uses his Poltergust 3000 to vacuum the Tuff Puffs.

The one in volume 29 is a longer version, and but travels along with Luigi.
