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 coloured Luigis in one of the modes. The host player can set the amount of floors to one of four options: 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 will be 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.

Modes

 * Hunter Mode: All Luigis work together to capture all ghosts on the floors before time runs out. Every 5 floors there is a mini boss and at the top there is a boss.
 * Rush Mode: Luigis try to escape each floor before time runs out.
 * Polterpup Mode: Luigis work together to capture all Polterpups on each floor.
 * Surprise Mode: A combination of the Hunter, Rush, and Polterpup modes. It can unlocked by completing the other three modes.

At the end of each floor, Red Coins appear. The more red coins a Luigi gets, the higher the chance of him winning the bonus item at the end of the floor.

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 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 Brothers: ''These Identical twin brothers sure have a blast playing with bombs!
 * Scarab Nabber: This ghost isn't exactly a people person. He gets downright grumpy when disturped, 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're likely to be teleported out of the room! I learnt that the hard way!
 * Primordial Goo: This ancient ghost here is your chief Creeper. Be careful around this fellow, or you might get more than you bargained for!
 * Creepy Creator: An Enormous ghost with the uncanny ability to produce other ghosts! I've never seen anything like it! I'd recommend ghost trackers 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.
 * Snug Thug: Slammers are mainly known for their strength, but this one's, but this one has enough brains to know that when it's cold, you need to wear a coat!
 * 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 realised he just wanted me to try on his fancy jacket. He could have just asked...
 * Spectral Sloth: 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 Pimpernal: 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.

Food Ghost Series

 * Spookumber: He may look like one of my favorite vegetables, but this ghost didn't come from a creeping vine. More like a creepy vine, right?
 * (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 all at once - if not to give people a big ol'fright, at least to get free popcorn at the cinema.
 * Scareambles (Known as Fright Egg in PAL versions): Eureka! This ghostly egg can reassemble itself once it's cracked!
 * Terrorange: Once he helped a farmer win a contest by pretending he was a gigantic orange. Don't ask me how I know that.

Halloween Ghost Series

 * Spooky Spook: He's not in costume; he's really retro.
 * Scool: There's no denying that he looks creepy, but he's actually a pretty interesting feller once you get to know him.
 * (PAL version) Skoul: On first impression, you might think this fellow is creepy, but once you get to know him....you know for sure.
 * Blimp Reaper: Instead of a scythe, he walks around with a giant roast turkey leg. Uh huh...
 * Blimp Reaper: Instead of a scythe, he walks around with a giant roast turkey leg. Uh huh...
 * Blimp Reaper: Instead of a scythe, he walks around with a giant roast turkey leg. Uh huh...

Bug Ghost Series

 * Dreadonfly: He doesn't have two pairs of wings. In fact, he doesn't have any wings. What good are wings on a ghost?
 * Lady Gug: Sure, his name might have "lady" in it, but nothing could be further from the truth.
 * Terrorfly: Criminy! I didn't think something so small could be so... terrifying! The size-to scare ratio of this little guy is off the charts!
 * Blobberfly: This ghost isn't anywhere near as graceful as a regular butterfly, or as harmless.
 * 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 humour 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 practising 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.
 * 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

 * Bad-minton: He's not bad, per se. He's just... really mischievous.
 * American Footbrawl: I'd stay out of his way unless you want to get tackled. Nothing like a bit of protective padding to bring out your boisterous side
 * Goolf: The only thing he enjoys more than playing golf is creating "hazards" on the green.
 * Tennis Menace: ''Careful with this one! He's been known to sneak onto tennis courts midmatch and cover the ball with ghostly goo!
 * Ball Hog: ''Whatever you do, don't try to pick him up or touch him with your hands! He hates that. Oddly, though, he doesn't seem to mind if you knock him around with your feet.

Animal Ghost Series

 * Awelligator (Known as Maligator in PAL versions): 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 versions0:I don't recommend pouring this ghostly bovine's milk over your cereal. Trust me on this. I'm still cleaning up the mess
