ScareScraper

The ScareScraper (known as the Thrill Tower in PAL versions) is the multiplayer mode of Luigi's Mansion: Dark Moon that is unlocked by completing Mission A-4 in the main game. It can be played online, locally or alone. It puts four 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 will 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.

Modes

 * Hunter Mode: All Luigis work together to capture all ghosts on the floors before time runs out. The time limit is 5 minutes.
 * 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 time pieces (for an additional 10 seconds) from furniture or clearing rooms of ghosts. 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 paw prints with the Dark-Light Device. The Luigis must first locate the kennel before the Polterpups can even be caught. The Luigis have 5 minutes to capture them all.
 * Surprise Mode: A combination of the Hunter, Rush, and Polterpup modes -- 2 Hunter, 1 Rush and 1 Polterpup floors in random order. It is unlocked by completing the other three modes on any difficulty/floor amount at least once.

At every fifth floor, a boss ghost is fought, regardless of the mode. At the top, The Brain is the boss, regardless (unless playing on Endless). The Luigis have 5 minutes to defeat the boss.

When a floor is completed, Red Coin Scramble! will occur: four Red Coins will 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 will reward 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 will have a bonus item randomly selected). The bonus items are the following:


 * Dark-Light Goggles: Reveals invisible objects and ghosts to players before even using the Dark-Light Device.
 * Poltergust x2 or x3: Increases the sucking power of the vacuum. Stacks with Poltergust Suction upgrades (once earned).
 * Restorator (Heal-Vac in the PAL version): Converts captured ghosts into hearts.
 * Map: Reveals the entire floor layout. This includes the exit (Rush Mode) and Polterpup (Polterpup Mode) locations. 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 or other furniture. A Luigi can have up to three bonus items 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 the players earn the Suction Level 3 upgrade, the next upgrades will always be 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 vase or carpet 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 a single Greenie (or sometimes, other ghosts) keeps 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 and a Greenie (or sometimes, other ghosts) spawns to deal damage to the affected player. 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 will still take damage, however.

Ghosts
Within the ScareScraper there are 47 ghosts that are only encountered in here (not including normal Polterpups). 1 of 45 of these ghosts are fought every fifth floor, and The Brain on the final floor. If a player is playing multiplayer without a game card, then the player sees special boss ghosts as simply larger, yellow, common ghosts.

Common Ghosts

 * Polterpup: Normally very playful and kind, the Polterpups started misbehaving after the Dark Moon shattered.
 * Big Polterpup: This pooch is big, so it might take more than one ghost hunter to keep him under control!
 * The Brain: This cunning host is the most evolved of all the Poltergeists. He awaits ghost hunters who are both brave and smart enough to match his powers.
 * (PAL version): This ghost is the most cunning of the Poltergeists. He awaits ghost trackers who are both brave and smart enough to match his powers.

Gold Ghost Series

 * Bomb Brother: ''These identical twin brothers sure have a blast playing with bombs!
 * Beetle Whisperer (Known as Scarab Nabber in PAL versions): This ghost isn't exactly a people person. He gets downright grumpy when disturbed, and won't hesitate to "introduce" you to his beetle friends.
 * Terrible Teleporter: These twin Sneakers are trouble with a capital T! Mess with them and you might end up being teleported out of the room! I learned that lesson the hard way.
 * (PAL version): These twin Sneakers are trouble with a capital T! Mess with them and you're likely to be teleported out of the room! I learned that the hard way!

 * Creeper Launcher (Known as Creeper Creator in PAL Versions): An enormous ghost with the uncanny ability to produce other ghosts! I've never seen anything like it! I'd recommend ghost hunters deal with him in a group, just to be safe.

Fashion Ghost Series

 * Fright Knight: Rumor has it that this Greenie comes from the middle ages, where he was a knight searching for a kidnapped princess. Sadly, wherever he went, she always seemed to be in another castle.
 * Cold Catcher: Even tough guys get chilly every now and then. Trust me. I speak from experience.
 * (PAL version) Snug Thug: Slammers are mainly known for their strength, but this one has enough brains to know that when it's cold, you need to wear a coat!
 * Freaker Sneaker: It seems this narcissistic ghost doesn't like to turn invisible because he wants everyone to see how good he looks. Bizarre.
 * (PAL version) Sleek Sneaker: It seems this narcissistic ghost doesn't like turning invisible because it makes it harder for the other ghosts to be dazzled by its fashion sense.
 * Tether Jacket: At first I thought he was trying to attack me, but then I realized he just wanted me to try on his fancy jacket. He could have just asked...
 * Yukata Ball (Known as Spectral Sloth in PAL versions): After a nice hot shower and with no other plans for the day, this Gobber slips right into his bathrobe and gets ready to lounge around. This ghost is living the dream.

Flower Ghost Series

 * Blue Pimpernel: I imagine he would have chosen green flowers instead of blue, but green flowers are surprisingly difficult to find. Go figure.
 * (PAL version): I imagine he would have chosen green flowers instead of blue, but green flowers are surprisingly difficult to find. Who would've guessed?

 * Pink Zinnia: Whenever he appears, he's hard to miss!
 * Violet: When he's in puddle form, he looks like a little garden dotted with beautiful flowers. It's really breathtaking...but not in a good way.
 * Daisy: When he's not hungry, he's probably as gentle as a freshly picked flower. Too bad he has a bottomless stomach.
 * (PAL version): When he's not hungry, he's probably as gentle as a freshly picked flower. Too bad we'll never know, though; this fellow has a bottomless stomach.

Food Ghost Series

 * (PAL version) Melon-choly: Although his body looks like a big ol' melon, the vertical stripes have a slimming effect.
 * Aweberry: His favorite thing to do is dip himself in mud and pretend it's chocolate. It's...odd, to say the least.
 * Scorn: This funny-looking ghost has kernels for teeth. I bet he wishes he could pop them when he smiles - if not to give people a big ol'fright, at least to get free popcorn at the movie theater.
 * (PAL version): This funny-looking ghost has kernels for teeth. I bet he wishes he could pop them all at once - if not to give people a big ol'fright, at least to get free popcorn at the cinema.
 * Scareambles (Fright Egg in PAL versions): Eureka! This ghostly egg can reassemble itself once it's cracked!

Halloween Ghost Series

 * Scool: There's no denying that he looks creepy, but he's actually a pretty interesting feller once you get to know him.

Bug Ghost Series

 * Blobberfly: This ghost isn't anywhere near as graceful as a regular butterfly, or as harmless.
 * Go-Bee: Incredible! This ghostly bee has glands that produce delicious spectral honey! Although, too much of the stuff will make your tongue numb. Take my word for it.
 * (PAL version) Grumble Bee: Instead of covering everything with goo, our stripey friend here prefers to splatter the walls and floors with honey. But be careful not to lick it! It'll make your tongue go numb.

Marine Ghost Series

 * Horrorca:  Fascinating! This ghost appears to speak fluent Whale!
 * Clown Fishy: The reason this fellow is so angry is because people keep thinking clown fish are actual clowns. They're not. No sense of humor whatsoever. Didn't laugh at any of my jokes.
 * Shriek Shark: The entire time I've been observing him, this tough looking spook has been practicing swimming through the air like a shark. Still needs some work.
 * Pondguin: I tried to feed him some fish, but he wouldn't eat them. He just kept trying to scare them. It didn't work.
 * Wurdle: This ghost would have you believe that he moves very slowly, but he's just trying to trick you. He's actually very fast!
 * (PAL version) Snapper: This ghost would have you believe that he moves really slowly, but don't be fooled - it's just an act. Yep, this one's not just crafty, he's pretty swift too!

Sport Ghost Series

 * (PAL version): He's not bad, per se. He's just... really mischievous.
 * Footbrawl: I'd stay out of his way unless you want to get tackled. He's been voted MVP of the ghost football league for three consecutive years!

 * Goolf: The only thing he enjoys more than playing golf is creating "hazards" on the green.

 * (PAL version) Maligator: Much like a real alligator, he hides under the water until someone steps a little too close.
 * Banegal: He tries to roar ferociously, but what comes out sounds more like an adorable kitty meowing. Don't tell him I said that.
 * Zebrawl: Between you and me, his striped camouflage seems a bit unnecessary considering he can turn invisible whenever he wants.
 * Leoprank: His hunting method is simple but effective: He waits until someone steps on him.
 * Cawe (Known as Full Moo in PAL versions): I don't recommend pouring this ghostly bovine's milk over your cereal. Trust me on this. I'm still cleaning up the mess.

Trivia

 * The ScareScraper uses two ghost themes from Gloomy Manor and one from the Treacherous Mansion.
