Super Mario Bros. is a platform game developed by Nintendo in late 1985 and published for the Nintendo Entertainment System, a sequel to the 1983 game, Mario Bros. In Super Mario Bros., Italian plumber Mario must save Princess Peach (Princess Toadstool in the US version) of the Mushroom Kingdom from the evil King Koopa (later known as Bowser). In two-player mode, Mario is aided in his quest by his brother, Luigi. In order to save Princess Peach, the Mario Bros. must conquer the eight worlds that comprise the Mushroom Kingdom. Mario (or Luigi) must make his way to the castle in each world and defeat one of the Bowser's evil minions. In order to reach each castle Mario or Luigi must battle through three "sub-worlds" by either destroying or avoiding Bowser's henchmen. If Mario or Luigi successfully fights his way through the castle and defeats the evil minion, a Mushroom Retainer (later called Toad), is freed. Inside the eighth castle, the Mario Bros. will find Princess Peach.
