New Super Mario Bros. 2

New Super Mario Bros. 2 (often called NSMB2) is a game for the Nintendo 3DS, by Nintendo. Though it is considered the sequel of New Super Mario Bros., it is actually the third (New Super Mario Bros. Wii preceding from it as the second) but this game takes place directly after New Super Mario Bros.. It is the thirteenth game in the Super Mario series and the eighth in the Super Mario Bros. series. This was also the first retail game to be available as a digital download in the Nintendo Eshop.

Story
Description from the American website: "Trouble always seems to find its way to the Mushroom  Kingdom! Just as Mario™ and Luigi™ go off on a coin hunt in  the sky, their beloved Princess Peach™ is kidnapped by the  dastardly Koopalings. The brothers have to venture through  over 80 stages to rescue her, grabbing an endless deluge  coins across land, water, air, ice and snow along the way."

Gameplay
The gameplay is very similar to previous the New Super Mario Bros. games. However, New Super Mario Bros. 2 focuses on collecting Coins, with many and varied ways to collect many coins at once, such as golden items that award the player many coins. Like New Super Mario Bros., the bottom screen displays a kind of map, showing the length of the level and where the player is. There are 9 Worlds, 6 main worlds and three special worlds. The item storage reappears too. Each world contains a random number of levels, including Ghost Houses, Fortresses and Castles. Reznors and Koopalings are found at the end of each fortress and castle, respectively.

A two-player mode is available, and the second player plays as Luigi, normally through the stages alongside Mario. This mode can only be played with two Nintendo 3DS consoles and two game cards. Another mode, the Coin Rush, challenges the player to collect the most coins they can in three randomly-selected levels through three different options. The Mushroom option will choose three levels from the starter worlds and a special world, the Fire Flower option chooses three levels from the middle worlds and the Star option choose three levels from the final worlds. In other words, Mushroom is the easy difficulty choice, Fire Flower is the medium choice and Star is the hard choice.

Also, Coin Rush records can be exchanged via Streetpass and challenged. Beating another player's record results in getting a Crown Coin (worth 1000 coins). SpotPassing allows the player to put their total into the Worldwide Coin Total.

The game's overall objective is to collect a million coins. The reward for collecting 1 million coins is a new title screen featuring a Gold Mario statue. Downloadable content will be available just after the launch of the game.
