ScareScraper

The ScareScraper (known as the Thrill Tower in PAL versions) is the multiplayer mode of Luigi's Mansion: Dark Moon. It can be played online, locally or alone. It puts four different coloured Luigis in one of the modes. The host player can set the amount of floors to one of four options: five, ten, twenty-five, and endless. The host can also select the difficulty of the mode with the options being between Normal, Hard, and Expert. If the amount of floors is set to endless, the difficulty will be automatically set to endless and cannot be changed. The final room is always the roof, unless it's set on Endless. The ghost bosses in the ScareScraper have different amounts of HP than their original versions in the main game.

The Scarescraper is unlocked after completing the first mansion of the game, Gloomy Manor where only Hunter Mode can be played. Polterpup, Rush and Endless modes are to be unlocked as the player completes more mansions
