Mario Bros. (マリオブラザーズ, Mario Burazāzu?) is an arcade game published and developed by Nintendo in 1983. It was developed by Shigeru Miyamoto, the creator of the Mario franchise. It is a follow-up to Donkey Kong and stars Mario, a plumber who was previously named "Jumpman". It has been commonly featured as a minigame in the Super Mario Advance series and other games. Mario Bros. has been re-released for the Wii's Virtual Console service in Japan, North America and some PAL regions.
In this game, Mario is portrayed as an Italian-American plumber who, along with his brother Luigi, has to defeat creatures that have been coming from the sewers below New York. The gameplay focuses on Mario's extermination of pests in the sewers by flipping them on their backs and kicking them away. The original versions of Mario Bros., the arcade version and the Nintendo Entertainment System (NES) version, received positive reception.
