Super Mario Bros. 2 for NES was released in October 1988 in North America.
"Super Mario Bros. - The Lost Levels" was released in 1986 for the Famicom Disk System under the name 'Super Mario Bros. 2'. It featured the same game-play and level design as the original "Super Mario Bros.
", with the addition of poison mushrooms and a much higher difficulty level than the first game. Due to the similarity in game-play to the original and its increased difficulty, this game was not brought to the West. The American game called Super Mario Bros. 2 is the most unusual game in the Mario series. In this game, Mario, Luigi, Princess Toadstool, and Toad have to save Subcon, the land of dreams, from Wart and his minions.
The reason that the American version of Super Mario Bros. 2 is so unusual is that it was made by making small changes to a Japanese game called "Doki Doki Panic : Yume Kojo" — a loose translation is "Heart Thumping Panic: Dream Factory". Various Nintendo of America employees personally despised the original Japanese Super Mario Bros. 2, which they found to be frustratingly difficult. Knowing such a game would likely sell poorly in the United States, they wanted to release a different sequel they thought would be friendlier to American audiences. Although Doki Doki Panic was originally set in a storybook and had an 'Arabian' theme completely unrelated to Mario, it was modified to use Mario sprites and music. With these small revisions, it was released to the U.S. market in October 1988 and featured on the cover of the very first issue of Nintendo Power magazine.

The American version of Super Mario Bros. 2 was eventually released in Japan for the Nintendo Family Computer under the name "Super Mario USA". It was also released as part of the Super Mario Collection in Japan (Super Mario All-Stars outside Japan).
Despite being a new, supposedly unrelated land from a game not initially intended to be a Mario game, Subcon is not all that unlike the Mushroom Kingdom. Instead of brick castles and giant mushrooms, however, Subcon is characterized by palm trees and red-and-white vases dotting the landscape. Though it lacks any underwater stages, Super Mario Bros. 2 introduces other concepts to the series — like desert stages complete with quicksand, or ice stages. Level 3-1 is notable for taking place against an enormous waterfall which the heroes must ascend.
Levels progress in a linear fashion, but for the first time Mario can backtrack. In the original Super Mario Bros., the screen could only scroll to the right.
