Super Mario Bros. 2: The Lost Levels

A downloadable version of the Game Boy classic, provided through Nintendo's Virtual Console service.

Originally released only in Japan, this follow-up to the blockbuster platformer Super Mario Bros. looked and played exactly like the original, but featured much harder stages, trickier challenges (which included killer mushrooms in addition to the power-up mushrooms), and differing abilities for Mario and Luigi. Because of the tremendous difficulty and similar game design, Nintendo of America decided not to publish this game in the States, instead converting a different Japanese game to become the second Super Mario title.
