Super Mario Bros. 2 (JPN)
Super Mario Bros.: The Lost Levels is the North American name for the Japanese Super Mario Bros. 2. It is called that because it was not released in North America until it was included in Super Mario All-Stars. Because The Lost Levels were too difficult, another game was released as the American Super Mario Bros. 2.
The plot of The Lost Levels is exactly the same as the original Super Mario Bros.: Mario and Luigi must rescue Princess Peach from the evil king of the Koopas, Bowser. Gameplay is basically the same, but there are some new additions.
The player can choose to play as Mario or Luigi, and each player has different physics. (Luigi can jump higher, but has worse traction) There is a new type of red Piranha Plant which keeps coming out regardless of the players' position. There are also upside down Piranha Plants. Some ? Blocks contain Poison Mushrooms, which harm the player if touched. There are red springboards which launch the player much higher than ever before, and in certain areas, the wind blows, which can affect jumps. Like the original game, The Lost Levels contains hidden warp zones. These can be used to skip whole worlds, but there is a special World 9 which can only be accessed if warps aren't used. Beyond the first eight worlds, there are an additional four worlds A-D.
The Lost Levels is considered by many to be the most difficult official Mario game, and indeed, one of the the most difficult games of all time. Bowser is not going easy on Mario in that game! An American version is available on the SNES as part of Super Mario All-Stars, and on the Wii's Virtual Console.
