While the original Luigi's Mansion was a solo outing, it doesn't look like that will be the case in the 3DS sequel Dark Moon.
"With so many new places to explore, all new ways to capture ghosts, and a brand new local multiplayer mode, Luigi's Mansion: Dark Moon is another star turn for Mario's heroic brother—and it's only on Nintendo 3DS," Nintendo's site reads.
We have no idea exactly what this local multiplayer will look like, but IGN is teasing an upcoming announcement, and considering the game is only two months away from release, there's no doubt we'll know more very soon.
