Mario Bros. is a 1983 platform game developed and published by Nintendo for arcades. It was designed by Shigeru Miyamoto and Gunpei Yokoi, Nintendo's chief engineer. Players control Italian twin brother plumbers Mario and Luigi as they exterminate turtle-like creatures, giant flies, and crabs emerging from the sewers of New York City by knocking them upside-down and kicking them away. The Famicom NES versions were received positively by critics. Elements introduced in Mario Bros., such as floating coins, enemy turtles, and Luigi, were carried over to Super Mario Bros. (1985) and became staples of the Mario series.
An updated version, titled Mario Bros. Classic, is included as a minigame in all of the Super Mario Advance series and Mario & Luigi: Superstar Saga (2003).
