In addition to the Hunter multiplayer mode, which we found out about a few weeks ago, Dark Moon will also feature two others: Rush and Polterpup. Rush Mode is a race to the finish of each floor, making the emphasis less on collection and destruction and more on getting through everything as quickly as possible. Polterpup Mode revolves around finding hidden ghost dogs throughout the levels. Most of these can be found with the Darklight, which is also used in single-player to find items and areas that are hidden in the environment.
Luigi's vacuum, the Poltergust, is getting even more use in Dark Moon. Like the original game, you use it primarily to duel with ghosts, but now the emphasis on puzzle solving is even greater. Luigi is shown using it to spin a ceiling fan so a key will fall down, fill up a balloon with air to move vertically between areas, and carry a torch to burn away spider webs.
During the broadcast, Miyamoto offered up this stark realization about the game's improbable vacuum: "If you try to suck up too much or something too big with an actual vacuum cleaner, it's a lot of work cleaning up the mess afterwards, but this is a video game, so you can just keep on sucking in as much as you want."
And in case you were worried about Mario's token ghost enemies skipping the festivities, Boos also make an appearance, though their full implementation in the game is unknown. We do know about the ghost dog, likely named Polterpup, who loves gold. He hides in the environment and you have to use the Darklight to follow his footprints and suck him up.
Luigi’s Mansion: Dark Moon is coming to North America on March 24, to Europe on March 28 and to Japan on March 20.
