The first new 2-D Mario platformer since Super Mario World has arrived. Boasting incredible 3-D graphics to accompany classic 2-D game play, this fast-paced adventure will have Mario fans cheering as they make their way over fields, under water, through castles and into the air. New and familiar enemies are everywhere, not to mention mind-blowing challenges made possible by the dual screens of the Nintendo DS. Not only that, but players can link wirelessly with a friend to play as Mario and Luigi in multiplayer mode.
