It's been more than 20 years since Super Mario Bros. first arrived, and now Mario and Luigi are back in an all-new platformer for Nintendo DS. Boasting incredible 3D graphics to accompany classic 2D gameplay, this fast-paced adventure will have Mario fans cheering. New Super Mario Bros. features eight all-new worlds, each filled with extra levels, hidden paths, and secrets galore. It's possible to complete the game without visiting every world, which means you'll have to track down many alternate exits to visit every nook and cranny in the game.<p>
