Luigi's Mansion (location)

Luigi's Mansion is a huge mansion constructed by the Boos that Luigi first encounters in the Nintendo GameCube game of the same name. Luigi wins the mansion in a contest that he entered and asks his brother to meet him there to celebrate. When he gets there, Luigi finds that the mansion is haunted and that Mario has been kidnapped. Luigi later meets Professor E. Gadd, who gives him the Poltergust 3000, which allows him to suck up Boos, Portrait Ghosts, Mouse Ghosts and other ghosts.

Luigi's Mansion
Towards the beginning of the game, Professor Elvin Gadd revealed to Luigi that the mansion was built by ghosts who had deceived Luigi. At the end of the game Luigi's Mansion is destroyed and rebuilt into a new form using Luigi's money collected by the player throughout the game. Inexplicably, the new mansion has only reappeared as a cameo in the background of the Luigi Circuit course in Mario Kart: Double Dash!!, while the regular, now-ruined mansion has reappeared several times. There is also an alternate version of the mansion known as the Hidden Mansion, which can be played after Luigi defeats King Boo. The Hidden Mansion is rather similar to the normal mansion of the game, but the entire mansion is mirrored from the normal one (only in the PAL version), and the ghosts and Boos are stronger. The Poltergust 3000 is roughly 1.5 times more powerful in the Hidden Mansion.

King Boo had a plan to get rid of the Mario Bros. (apparently due to the trouble they had caused him in the past), so he sent a message to Luigi and Mario that Luigi had won a mansion in a contest, so they went there to celebrate. However, Mario arrived first and was captured by King Boo and sealed away in a portrait. When Luigi arrived, Mario wasn't there, but Luigi (as mentioned) ended King Boo's plan and destroyed the mansion.

Mario Kart series
Luigi's Mansion is also the name for certain racing courses found in the Mario Kart series. The courses take place in the mansion of Luigi and surroundings, showing as well the environment as seen in the game Luigi's Mansion. The Luigi's Mansion course has appeared in two Mario Kart games so far, which one would be an alternative to replace the Luigi Circuit, from many Mario racing installments.

Mario Kart: Double Dash!!
Luigi's Mansion made its race course debut in Mario Kart: Double Dash!! as an unlockable battle course. In the game, it was actually revealed to be a battle course that contained a winding maze of three floors. The second floor is a wide room where all the racers start their battle. The first floor is a corridor where it is possible to place some traps down, especially near the Item Boxes scattered in the hall. The third floor is actually the roof terrace, where, unlike the other zones, there are no Item Boxes. The center of the terrace is a gap where the racers fall directly to the second floor. All the floors are connected together by bended corridors, three leading to the first floor and one to the terrace. Some of the specters' portraits from the game Luigi's Mansion appear within the stage.

Mario Kart DS
In the game Mario Kart DS, Luigi's Mansion is the last race course of the Mushroom Cup. Outside the mansion is Boo Woods which has a graveyard surrounding the mansion and beyond it, a swamp of mud with strange walking trees. When a character runs into one of these trees, instead of spinning out or rolling over, the character instead will just get stuck on the tree as if it were a wall.

Racers start outside the mansion in a section of Boo Woods, they will go through a curl path to the entrance of the mansion, running along of a narrow hall that leads the racers downwards to a room beneath the lobby. Characters then go out of the house, crossing a stone path tunnel, where they reach the graveyard, leaving the mansion. Finally, racers end up crossing the swamp to cross the checkered line.

The missions 1-6 and 2-4 take place on this course, with Luigi driving in both of them.

Portrait ghosts such as Chauncey and King Boo can be found.

''Mario & Luigi: Partners in Time
While the mansion is never seen in Mario & Luigi: Partners in Time it is alluded to after the eruption of Thwomp Volcano. The volcano destroys the young Professor E. Gadd's lab at the base of the volcano, prompting him to ponder moving his research to Boo Woods. While also never seen, it is known that Boo Woods is the location of his lab seen in Luigi's Mansion.

Mario Power Tennis
Luigi's Mansion Court is a default court in Mario Power Tennis, and is likely set in the Courtyard. There are numerous ghosts watching the game. In the normal version of this court, it is set on a concrete field, with no real gimmicks in it. In the gimmick version, on occasion,a ghost will appear on either side of the court, and start harassing the player(s). This will slow them down, and they will also have a tough time hitting the ball at the right time as well. However, if a player lands the ball onto the mid-back space on the court (which has a picture of a light bulb on it), all the ghosts on the other side of the court will disappear. The Mini-Game Terror Tennis is held on this court. Unlike Mario Kart: Double Dash!! this mansion actually is the mansion (presumably in it's older form) seen in Luigi's Mansion.

''Mario Hoops 3-on-3
It appears in Mario Hoops 3-on-3 as the second playable court in the Flower Tourney. Ghosts abound on the court and will grab the ball should it cross their path. Players must jump to grab the ball back. If the player activates the Lightning, the ghosts will disappear for a short period of time.

Super Smash Bros. Brawl
In Super Smash Bros Brawl, Luigi's Mansion is an unlockable battle stage. The stage shows 5 rooms from Luigi's Mansion (based upon the Nursery, the Kitchen, the Study, the Ball Room, and the Foyer), and the mansion itself is destructible. Players can destroy a part of it by attacking the poles in the separate rooms. When a player does this a few Boos will appear and then quickly fade away. If players destroy all the poles, the stage will just be flat. Later, the stage will rebuild itself. Also, if all the players are not in any of the rooms and the mansion is whole, it shows the front of the mansion.

Mario Super Sluggers
Luigi's Mansion is a playable stadium in Mario Super Sluggers. The stadium is located in the backyard of the mansion itself, and features gravestones located throughout an over-grown outfield. Coming within a certain range of the stone causes a generic ghost from the mansion to attack the player. It can only be accessed by playing nighttime game. It can be entered when the player purchases Luigi's Flashlight for 300 coins from the Mario Stadium shop. Thick grass grows in the outfield, making it difficult for the players to find the ball.

The stadium's mini-game is called Ghost K. It involves the player throwing balls at colored ghosts in attempt to get the highest score.

Mario Sports Mix
Luigi's Mansion made an appearance in Mario Sports Mix as a volleyball and basketball court. During a basketball match, one of the ghosts may snatch the ball out of the player's hand and pass it off to one of their opponents. When playing volleyball, the volleyball net is covered in spider webs. The volleyball and basketball match appears to take place inside.

Trivia

 * Luigi's Mansion is mentioned by one of the crows in Twilight Town in Paper Mario: The Thousand-Year Door.
 * The Foyer of the mansion appears in the Mansion Patrol mini-game of Super Paper Mario. The Foyer is here depicted as black and lined with empty portraits, making it look rather different than its other depictions, though the Nintendo Power player's guide for Super Paper Mario actually referred to it directly as "a Luigi's Mansion foyer".
 * In Mario Kart DS, portraits such as Chauncey and King Boo can be seen inside the mansion.
 * The Area Keys and the key to the Secret Altar of Luigi's Mansion resemble playing card suits. As such, Area Two has a heart shape on its door, Area Three has a club shape on its door, Area Four has a diamond shape on its door, and the Secret Altar has a spade shape on its door.
