Luigi's Mansion: Dark Moon

Luigi's Mansion: Dark Moon, also known as Luigi's Mansion 2 in European and Australian regions (or Luigi Mansion 2 in Japan), is an upcoming Nintendo 3DS game that will serve as the sequel to Luigi's Mansion (which was released for the Nintendo GameCube). The game is to be released on March 20th in Japan, with North America getting the game on the 24th and Europe on the 28th. The Australian release is also in March, but a specific date has yet to be announced.

Plot
Professor E. Gadd has been researching ghosts in Evershade Valley, but when the Dark Moon shatters, the once friendly ghosts turn evil. He then calls upon Luigi to search for the scattered pieces of the Dark Moon and solve this problem and mystery.

Gameplay
In this game, the Dark Moon has shattered and Luigi needs to find the Dark Moon pieces. So far six mansions have been confirmed (with one mansion being exclusive to multiplayer mode.), which will have multiple missions each in them. The game also introduces the Poltergust 5000, the Poltergust 3000's upgrade. Shining light via flashlight is no longer sufficient to stun all the ghosts in the game; players now need to activate the Strobulb to stun ghosts. The Flash Light has another feature called Dark-Light, which will shine a rainbow colored light to find things such as the path of Boos or invisible objects. Luigi will also be given the Dual Scream, which is an original Nintendo DS. It will act the same way as the Game Boy Horror and will display a map on the 3DS's bottom screen. Cash and gems help with the mission score, as well as with upgrades to the Poltergust 5000. The game is said to be a lot more puzzle-oriented.

Scarescraper
Unlike its predecessor, Luigi's Mansion: Dark Moon includes a multiplayer mode called the Scarescraper (known as Trill Tower in PAL versions), a series of floors where up to four players can play. The Scarescraper may have a chosen amount of rooms ranging from five to infinite. Along with being local multiplayer, it is also online multiplayer. There are at least three modes confirmed, these include:
 * Hunter Mode - Players will need to capture all the ghosts in order to advance to the next floor.
 * Rush Mode - Players will need to reach the hatch within the allotted time.
 * Polterpup Mode - Players will need to chase down and capture all the Polterpups.

Locations
Unlike the first game, where there was only one mansion, Dark Moon features different themed mansions that Luigi can explore, thanks to E. Gadd's new teleport system. Every Mansion has various number of missions. The game has six mansions in total (with a seventh mansion being exclusive to Multiplayer), each with a theme in a similar fashion to the mainstream Mario games. So far, two of these have been given offical names:

The other two, which are unnamed are:

Nintendo eShop Description

Trivia

 * In the latest trailer, which was released in the 3DS Software Showcase at E3 2012, the arrangement of pause menu BGM of Mario Strikers Charged is heard at the last elevator scene. Both games were developed by Next Level Games.
 * In the previous game, Luigi had the Game Boy Horror for communication, which was based off the Game Boy Color. In this game, Luigi uses the Dual Scream, which resembles yet another Nintendo handheld console, also for communicating. Its ringtone is the first game's main theme as well as E. Gadd's theme.
 * In the first Mansion, Luigi opens the main door and says "...Hello?" in a scared voice. This is a tribute to the first game's opening sequence.
