Luigi's Mansion: Dark Moon

You can begin a new game by selecting a file from the main menu, then opting to start a new game. You can also delete an old file if you need to, or press A+B+X+Y as you start up the game anew. Once you do, you'll begin by watching some introductory movies.

It all begins with Professor E. Gadd in his lab. The green ghosts nearby are benign. Outside, though, trouble brews. A dark Boo rises up in the sky towards the Dark Moon and, with the power of the gem on his head, shatters it and scatters the fragments across the land. The green ghosts suddenly turn, losing their eyeballs and wrecking the lab.

In some house, Luigi has fallen asleep while watching the television. Soon, he is awakened by some creepy noise coming from the TV. E. Gadd's face appears on-screen, notifying Luigi of the ghosts' hostility and requesting his help, forcibly dragging him through the screen to his lab.

After some small chat on the other side, E. Gadd decides to fill in the details. He shows you a picture of the Dark Moon, an odd celestial object that turns ghosts in Evershade Valley into rather harmless creatures. E. Gadd studied these peaceful ghosts until the aforementioned events occurred. He quickly left the Gloomy Manor and found the Dark Moon vanished from the sky, and a dark, dense fog all around.

E. Gadd fears that the ghosts will soon terrorize other areas beside the Valley. He has found one fragment of the Dark Moon, though - but only a fragment. And, even then, it seems that something has corrupted it. With some strange device, he fixes the fragment, dispersing some of the fog near the Bunker. This end result shows that the Gloomy Manor is reachable, and fixing the Dark Moon in whole will fix their problems.

He then asks Luigi for his help, answering his own question before Luigi is given a real choice.

If you want to back out to select a game mode, you can press the B Button - you can do Scarescraper (a multiplayer mode) and enter E. Gadd's Vault, although those are not yet unlocked. You can back out further to the title screen. Otherwise, mash the A Button until you start Gloomy Manor: Mission A-1: Poltergust 5000.
