Luigi's Mansion: Dark Moon -- More Mansions. More Fun.

The Dark Moon shines over Everglade Valley. E. Gadd has lab here, where he does research with the friendly ghosts in the area. King Boo appears in the sky and blasts the Dark Moon with the jewel in his crown, causing the Dark Moon to shatter and fall to the ground in different places. The ghosts in the lab suddenly turn vicious and tear E. Gadd's lab apart. Gadd runs off, terrified. Meanwhile, Luigi is asleep in front of the TV in his house, which looks like a Rank E mansion from Luigi's previous adventure. The TV screen turns to static, then Gadd appears on screen. This scares Luigi. Gadd needs Luigi's help because of the hostile ghosts. He uses the Pixelator to bring Luigi through the TV to his lab. Gadd is excited to see Luigi and he knew their paths would cross again. Luigi's in Gadd's Bunker, which is perfectly safe. Gadd's been continuing his paranormal research. He became an authority in the field after their last adventure. He shows Luigi the Dark Moon, which has a pacifying effect on the ghosts in Evershade Valley. Gadd leapt at the opportunity to study ghosts in a peaceful environment. His research was going very well, until the ghosts snapped and turned hostile. Gadd fled from Gloomy Manor and hid in the Bunker, where the ghosts won't find him. Gadd noticed that the Dark Moon had vanished and Evershade Valley had been enveloped in an eerie fog. He thinks the Dark Moon's disappearance is the cause. He's worried that the ghosts might leave and terrorize the world beyond the valley. He found a fragment of the Dark Moon nearby, which means it's broken. It also seems corrupted by some strange energy. The energy might be suppressing the Dark Moon's pacifying effect on ghosts. On the bright side, Gadd has inventions to help out. He gets out a device that cleans the Dark Moon, which dispels some of the fog, revealing one of the mansions. Gloomy Manor is now accessible. Gadd wants to find the other Dark Moon fragments to return Evershade Valley to normal. Luigi will have to contain the ghosts in the meanwhile. He's the best (and only) ghost wrangler Gadd knows.

The Poltergust 5000 is in Gloomy Manor, so Luigi will have to go get it. It's Luigi's first mission. The goal is to collect 2000 G while we're there.

Once again, Luigi must fight ghosts solo. It started a little like Paper Mario: Sticker Star, but this is all about Luigi. Let's get going!
