Even though they're mostly associated with Nintendo's line of home gaming consoles, Italian plumber brothers Mario and Luigi started their journey to digital stardom in the coin-op arcades. In the early '80s, Mario first appeared in the arcade classic Donkey Kong, and Luigi made his debut in Mario Bros. They've spent most of their time since then in console-only games but it appears that Luigi hasn't forgotten his roots, since he's the star of the new Luigi Mansion Arcade game that was recently released in Japan.
Luigi Mansion Arcade is a first-person rail shooter along the lines of House of the Dead, although it takes its plot, settings and characters from the Luigi Mansion games that were previously released on the Nintendo GameCube and 3DS. In the game, up to two players explore a haunted mansion and use the Poltergust 3000 to capture a selection of ghosts.
As you can see from the video below, Luigi Mansion Arcade looks like loads of fun. I'm sure that this game will eventually wind up in the U.S., although I'd much prefer to see it ported for the Wii U system because it would fit perfectly with that system's motion controls.
