Super Mario Bros: Dual Dash is a curious remake of Super Mario Bros where you play with Mario and Luigi at the same time. Or, if you prefer, you can let a friend take over Luigi.
The story is the following: the Mushroom King is in danger, and the only way to protect him is transport him from his enemies (in four phases) to Bowser´s castle. Mario and Luigi try to move him there between them, always taking care, because if not the mission could fail. Thus it´s a complicated game where you have to join your characters´skills to win.
With two players you can also have two cameras. The first works normally, while the second divides the screen horizontally, to see at any moment where the two characters are and control them. Just press Intro to hide this option.
