ScareScraper

The ScareScraper (known as the Thrill Tower in the British English version) is the multiplayer mode of Luigi's Mansion: Dark Moon that is unlocked by completing the fourth mission, Visual Tricks, in the main game. It can be played online, locally or alone. The game puts four (plus other four different colored Gooigis in Luigi's Mansion 3) different colored Luigis in one of the modes. The host player can set the amount of floors to five, ten, twenty-five, and endless, as well as the difficulty of the mode: Normal, Hard, and Expert. The endless floor option is available only for the chosen mode once the 25 floors of that game mode are cleared. If the amount of floors is set to endless, the difficulty is automatically set to endless and cannot be changed. The final room is always the roof, unless it is set on Endless. The ghost bosses in the ScareScraper have different amounts of HP than their original versions in the main game, and for every five floors cleared, non-boss ghosts gain 5 additional health.

The game ends when all Luigis are KO'd (or trapped), or when they do not complete a floor in an amount of time. Other Luigis can revive a fainted Luigi by pressing near him to revive him. This brings his HP back to 20, and it releases hearts. Luigis can communicate with each other (even when KO'd) when the player either presses the or touches the touchscreen.

In Luigi's Mansion 3, every ScareScraper floor features a different objective.

Players

 * Luigi with green cap, Poltergust, and overalls (Player 1)
 * Luigi with blue cap, Poltergust, and overalls (Player 2)
 * Luigi with orange cap, Poltergust, and overalls (Player 3)
 * Luigi with pink cap, Poltergust, and overalls (Player 4)

When playing a ScareScraper, Luigis are colored depending on the order of when they join it, meaning that the player is always an all-green Luigi when playing solo on their own ScareScraper or hosting it for other players. In Luigi's Mansion 3, the color of each player's Gooigi corresponds to their cap color.

Hunter Mode
All Luigis work together to capture all ghosts on the floors before time runs out. A gauge on the right side of the bottom screen shows ghostly activity that empties as ghosts are captured. Depending on the difficulty, such as in Endless mode, Strong versions of ghosts may appear in earlier floors. The time limit is 5 minutes per floor.

Rush Mode
Luigis try to escape each floor by reaching the exit and stepping on the switches before time runs out. The timer starts at 30 seconds, but the time limit can be extended by collecting timepieces (for an additional 10 seconds) from paintings and furniture, or by clearing rooms of ghosts. Rush Mode does not have locked doors or keys, however, Gobbers may occasionally drop from ceilings in dark rooms and block the doors with its goo; they must be captured in order to proceed.

Polterpup Mode
Luigis work together to capture all Polterpups on each floor by following their invisible paw prints with the Dark-Light Device. The Luigis must first locate the kennel before the Polterpups can even be caught. Sometimes Polterpups may even summon other ghosts to hinder progress. Depending on the difficulty of the ScareScraper, the amount of Polterpups to be captured on a floor vary, ranging from a minimum of 2 Polterpups to a maximum of 6. The Luigis have 5 minutes to capture them all.

Surprise Mode
A combination of the Hunter, Rush, and Polterpup Modes &mdash; two Hunter Mode floors, one Rush Mode floor, and one Polterpup Mode floor in random order. It is unlocked by completing the other three modes on any difficulty/floor amount at least once and beating Dark Moon Quest.

Boss Floors
On every fifth floor, a boss ghost is fought, regardless of the mode. On the final floor, The Brain is always the boss (unless playing on Endless). Boss ghosts are assisted by regular ghosts as the Luigis vacuum them up, with more regular ghosts appearing with more players. The Luigis have 5 minutes to defeat the boss.

After clearing a Boss Floor, all ghosts' HP increase by 5, other than bosses. This only affects them if the host player selects more than 5 floors.

Bonuses
When a floor is completed, the Red Coin Scramble! occurs: four Red Coins appear in random rooms and the Luigis have 20 seconds to collect them all for a chance to play Red Coin Bonus! (a sole Luigi has an all-or-nothing chance to play). The bonus game rewards a Luigi with a bonus item if their icon stops next to it. The more Red Coins a Luigi gets, the more consecutive icons of his appear in the roulette, increasing his chances of winning the bonus item at the end of the floor (a sole Luigi has a bonus item randomly selected). The bonus items consist of the following:


 * Dark-Light Goggles - Reveals invisible objects and ghosts to players before the Dark-Light Device is used.
 * Poltergust x2 or x3 - Increases the sucking power of the vacuum. Stacks with Poltergust Suction upgrades (once earned).
 * Restorator (Heal-Vac in the British English version) - Converts captured ghosts into hearts.
 * Map - Reveals the entire floor layout. This includes the exit (in Rush Mode) and Polterpup locations (in Polterpup Mode). In Rush Mode, a map can sometimes be obtained once a dark room that it's in is cleared of ghosts.

Bonus items take effect only on the next floor. Sometimes a bonus item can even be found in vases, paintings, or other furniture. A Luigi can have up to three bonus items equipped at a time.

Upgrades
Upgrades are rewarded to the entire team if they reach certain treasure totals. These totals differ depending on the mode being played. Once players earn the Suction Level 3 upgrade, the next upgrades is always Heart Drops up until a certain point. Unlike in Dark Moon Quest, the upgrades are not permanent; the next time the Luigis play another ScareScraper, they must earn these upgrades again.

Traps
There are three different traps that the Luigis can encounter. All of these traps require help of a teammate to relieve the player of these status conditions. This also means there are no traps if there is a single Luigi playing as there is no one to help him. If all players are stuck in traps, the game is over.


 * A player can get trapped by a carpet in a room. Another player needs to vacuum carpet tassel in order to pull the player free. The room remains dark until the player gets freed, and ghosts keep spawning to damage the trapped player.
 * A player has a chance of getting cursed when inspecting furniture. The curse reverses a player's controls, and it can be spread if the affected player makes contact with another player. Cursed players drop their bonus items, if any, and cannot pick them up. A player has to shine the Dark-Light Device on the affected player to relieve the player of the conditions.
 * A player has a chance of getting stuck in a large vase upon inspecting it. The affected player is unable to do anything other than moving. Another player has to vacuum and pull a dangling cord in order to free the player. The room remains dark until the player gets freed. Ghosts keep spawning to deal damage to the affected player until the vase is removed. This can be avoided if the player vacuums the vase with the Poltergust beforehand to see if it wobbles or not -- vases that don't wobble are traps. If there are any active suits of armor available in the room while the Luigi is trapped, the Luigi can free himself if he can make the suit of armor shatter the vase with its sword; the player still takes damage, however.

Totals
At the end of each floor, the players can view statistics of their activity on the floor they completed on the top screen. Upon completing -- or losing in -- a ScareScraper, the Luigis are ranked based on their performance (e.g. capturing ghosts and avoiding traps, and taking as little damage as possible) and are rewarded in G for the Vault. The higher ranked a Luigi is and the more floors they have cleared, the larger the prize.


 * Amount of spectral mass (W) obtained from ghosts.
 * Amount of treasure (G) collected.
 * Amount of ghosts captured.
 * Amount of ghost HP drained.
 * Amount of times KO'd.
 * Amount of damage taken.
 * Amount of times cursed.
 * Amount of times trapped (in vases or carpet traps).

After defeating a boss ghost, the player can view the total statistics of all the floors they completed so far, after viewing the statistics of the floor they just completed.

Achievements
In the results screen, before all the players are ready to begin the next floor, they can see achievements they have obtained on the floor they just cleared on the bottom screen. These achievements are based on their performance, but they're otherwise there just for fun.


 * MVP / Master Tracker - Most Ghosts Captured
 * Workhorse - Most Ghost HP Drained
 * Life Support - Most Hearts Collected
 * Money Maker - Most Treasure Collected
 * Heavy Lifter - Most Boss HP Drained

Ghosts
There are 47 ghosts encountered solely within the ScareScraper (not including normal Polterpups). One of 45 of these ghosts (excluding the Big Polterpup and The Brain) are fought on every fifth floor, and The Brain is fought on the final floor. If the player is playing multiplayer without a game card, then they see special boss ghosts simply as larger, yellow, common ghosts.

Trivia

 * The ScareScraper uses two ghost themes from Gloomy Manor and one from the Treacherous Mansion.
 * If the Luigis manage to climb more than 99 floors in a ScareScraper on Endless, the game stops counting at 99.
 * One of the fashion ghosts, the Fright Knight, references the original Super Mario Bros., where his description says, "He tried to rescue the princess, but she was always in another castle".
 * In an interview with Next Level Games, it is revealed having Mario, Toad, and Peach was considered at one point, but they would not fit the space for Download Play, which is limited to 32 MB.
 * According to an Iwata Asks interview, Luigi's Ghost Mansion helped adjust a mechanic used in the ScareScraper. Originally, the developers wanted a fallen Luigi to stay dead and could not be revived. After playing Luigi's Ghost Mansion, they changed it so other players could revive a fallen Luigi.
