Mario Bros.
Developer: Nintendo R&D1 Publisher: Nintendo Platform: Arcade (Custom) Released in JP: July 14, 1983 Released in US: July 20, 1983 This game has unused graphics. This game has regional differences.

Mario and Luigi go into the sewers to take out turtles, crabs, and flies. Probably the only game that centers around Mario and Luigi actually plumbing.

Unused Graphics

A snake-like creature who could've been a fourth enemy type.

Unused poses for Mario (and Luigi). The first pose appears to be an alternate version of one of Mario's sprites shown when jumped on by the other player, although this version seems to have some incorrect pixels. The second pose appears to be Mario sitting down and letting out a breath, indicated by the white cloud (similar to when a level is finished in the Game and Watch version of the game). The third and fourth poses almost look like Mario riding something, but it's unknown what they were for.

Gameplay

• Phase 2 of the Japanese version, featuring four Shellcreepers, was removed from the American version. All future Nintendo-developed ports of the game (such as the NES version and Mario Bros. Classic) would retain it in all regions.
• In the Japanese version, you get an extra life at 20,000 points and every 30,000 points afterward. In the American version simplified this to awarding an extra life every 20,000 points.
