For months, we’ve been hearing about Mario and Luigi RPG 3, a Japan-only Nintendo DS game. Now, that game is making its way to our shores, with the new title Mario and Luigi: Bowser’s Inside Story.

Players will control Mario and Luigi as they fight their way through Bowser’s insides. Players will also control Bowser, using him to solve puzzles blocking Mario and Luigi’s path. Bowser will also get into a few fights, some of which will call for turning the DS on its side.

No firm release date was given, but we do know it’ll be out this fall. Stay tuned for more!
