Super Mario Bros. puts players in control of Mario, an Italian plumber, as he makes his way through 2D, side-scrolling levels with platforming challenges and hostile enemies. His goal is to rescue Princess Peach from Bowser, King of the Koopa.
The Koopa have invaded the Mushroom Kingdom and transformed its inhabitants into objects and plants. The captive princess alone can reverse the spell, making her rescue essential to restoring the kingdom.
