Mario Bros. is a classic video game developed and published by Nintendo in 1983. It is a side-scrolling platform game featuring the two protagonists, Mario and Luigi, as they navigate through the Mushroom Kingdom to save Princess Toadstool from the antagonist Bowser. The game has become one of the most iconic titles in gaming history and has spawned numerous sequels and spin-offs. The term 'SUPER' is often used to describe the game, as it was one of the first games to feature the now-iconic power-ups that allowed players to gain special abilities.
