Luigi's Mansion: Dark Moon is the sequel to Luigi's Mansion. It was released March 20th, 2013 in Japan, March 24th, 2013 in North America, and March 28th, 2013 in Europe.
Luigi's Mansion: Dark Moon will contain at least six mansions and will introduce the Poltergust 5000, which is an upgrade from the Poltergust 3000 since in the first Luigi's Mansion. It will be able to suck up ghosts and as well have several new features. The game will have multiple missions and mission-based challenges.
Professor E. Gadd has been doing research about the ghosts in Evershade Valley, when one night King Boo suddenly appears and shatters the Dark Moon. The pieces of the Moon are scattered into each mansion of the valley, where the once friendly ghosts, are now evil.
While at home, Luigi is sleeping while watching the TV, until E. Gadd appears on the television screen and informs him about the situation. E. Gadd then uses the Pixelator to transport Luigi through the screen to Evershade Valley to help search for the broken pieces of the Dark Moon.
After the Dark Moon is shattered, Luigi will have find the Dark Moon pieces. There is a total of six mansions so far confirmed(one mansion is used for multiplayer mode), which will have multiple mansions inside of each of them. The Poltergust 5000 is also new to the game and is the upgrade to the Poltergust 3000. Shining a light with the flashlight no longer stuns all of the ghosts, so now the players will have to activate the Strobulb to stun them. The Flash Light now has a new featured called the Dark-Light, where it will shine a rainbow-colored light to find things like a path of a Boo or invisible objects. E. Gadd will give Luigi the Dual Scream, which is just an original Nintendo DS and act like the Game Boy Horror did in Luigi's Mansion. It will display the map on the 3DS's bottom screen. Like the previous game, cash and gems will help for the mission score and as well upgrades to the Poltergust 5000.
Luigi's Mansion: Dark Moon will also include a multiplayer mode in the game called Scarescraper or Trill Tower in the PAL version. This mode will include a series of floors where four players are able to play on. The Scarescraper will choose the amount of rooms that will range from five to infinite. This mode will be local and online multiplayer. There will be three modes in this mode:
- Hunter Mode - Players will catch all ghosts before proceeding to the next floor.
- Rush Mode - Players have to reach the hatch in the allotted time.
- Polterpup Mode - Players will have to chase and capture all Polterpups.
