Luigi's Mansion 2

Luigi's Mansion 2 (Japanese: ルイージマンション2 Luigi Mansion 2), also known as Luigi's Mansion Dark Moon in North America, is the sequel to Luigi's Mansion for the Nintendo GameCube. Luigi's Mansion 2 was released for the Nintendo 3DS in 2013.

Gameplay
There is now an upgrade to the Poltergust 3000, the Poltergust 5000. Simply shining the flashlight on ghosts no longer stun them because sometimes they wear shades to destroy troublesome spooks. The player must activate a strobe-like function. It is also a lot more puzzle-oriented than the first game.

 * Slammers are buff, red ghosts with 30 HP.
 * Gates that are similar to the vines that blocked doorways in Luigi's Mansion. Unlike the game's predecessor, it not only blocks doors, but also blocks stairways.
 * Haunted Armor that will attack Luigi with their swords if he gets too close.
 * Poltergeists, orange ghosts with a pink brain that have 50 HP.
 * Gobbers, large, yellow ghosts with 100 HP.
 * Hiders, skinny, blue ghosts with 15 HP.
 * Sneakers, pink ghosts that have 25 HP.
 * Polterpups, dog ghosts with 50 HP. They will revive Luigi if he has a Gold Dog Bone.
 * Creepers, jelliton, like ghosts with infinity HP. They can get sucked up with a power suck.
 * Boos, round, white ghosts with sharp teeth. They are one of the main ghosts in the game.
 * Mummy-like ghosts, that are actually Greenies in disguise.
 * Ghost tarantulas that are purple when they crawl down the wall and brown when they crawl on the floor.
 * Possessor Ghosts, white, ram-like ghosts that serve as bosses. They possess other beings (like spiders) or non living objects (like stairs or clocks). They have infinite HP, until Luigi uses a power suck three times to completely suck them up.
 * All of the Evershade Valley Ghosts, with the exception of the Possessors and Polterpup, have crystalline forms called 'Strong' forms.
