Luigi's Mansion: Dark Moon

Luigi's Mansion: Dark Moon (known as Luigi's Mansion 2 in the Europe/Australia regions and 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).

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

Gameplay
The game is confirmed to have at least three mansions, which will have multiple missions 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 ghosts in the game. Players need to activate the Strobe Light to stun the ghosts. In this game, the Dark Moon has shattered and Luigi needs to find the Dark Moon pieces. The Flash Light has another feature called, Dark Light, which will shine a rainbow colored light to find thing such as the path of Boos or invisible objects. Cash and gems help with the mission score, as well as for upgrades to the Poltergust 5000. The game is said to be a lot more puzzle-oriented.

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.
