- In an all new 2D side-scrolling adventure, Mario and Luigi return since Super Mario World.
- The character models are rendered in real time 3D, allowing for a far greater number of moves ever before seen in a Mario Bros. title. Also as the game is on DS, the touch screen allows players to store an additional power-up and view the distance still to go in a level.
- Bowser and Bowser Jr. has kidnapped Princess Peach, and of course, it is up to Mario and Luigi to rescue her and take down the troublemakers.
- There are eight new worlds to explore, much like in Mario 3: they are Plains, Desert, Tropical Island, Forest, Ice, Mountains, Sky, and Bowser's Lair.
- The eight worlds have eighty distinct levels as well as many secrets that will only be found on careful examination.
- There are also many new power-ups (the mega mushroom and Koopa shell, for instance) for the brothers to collect.
