Plumbers Mario and Luigi must dispose of all the critters coming out of pipes in the action-packed arcade game that initiated the most popular video game franchise of all time. Two players can cooperate and compete in one of the first multiplayer hits of Nintendo.

As its title suggests, Mario Bros.™ marks the first apparition of Mario's brother Luigi when two players compete together. The game also introduces several staples of the franchise. Mario is now a plumber (instead of a carpenter in Donkey Kong™), faces turtle-like enemies and can collect coins in bonus stages. However be careful, it is not yet possible to directly jump on enemies like in further episodes. Find a way to make them inoffensive beforehand.
