Players frequently will have to split up the pairs of bros. to solve puzzles, oftentimes exploring both screens on the DS. In battle, they'll use items and both sets of bros. to dodge enemy attacks and deal their own damage. As the game progresses, they'll learn more and more combination moves, like the Spin Jump, Hammer Dive and Ball Bros. The new Nintendo DS Rumble Pak fits into the secondary expansion slot that normally houses Game Boy Advance games on the DS. Multiple actions in the game, such as explosions, lucky hits or attacks, trigger vibrations from the Rumble Pak.

The second screen will quickly become the players' best friend as they use it to study the land, keep track of the pair of bros. not under their control and even maximize combo moves in battle.
