Nintendo 3DS

Nintendo 3DS is a starter stage in Super Smash Flash 2. Battle takes place on top of the handheld console, which randomly changes the colour of the console in 3 different possibilities right inmediately after the battle has begun. Similarly to WarioWare, Inc., Nintendo 3DS interacts with the fighters setting one theme that affects the battle somehow, based around different indy games avalaible for download for the console in the real life. Though technically not considered part of the DS family by Nintendo, Nintendo 3DS is catalogued in SSF2 as a property of the Nintendo DS universe.

Layout
Battle takes on the giant Nintendo 3DS floating on deep space. Normally, the 3DS is just a hard platform with nothing more that ledges to grab, however, the games change on the top screen of 3DS each time after the specific game is over. The game available are Bit.Trip Runner, Mutant Mudds, Tetris: Axis and VVVVVV. Whenever a game plays, the camera changes to a fixed-angle so players can see the whole stage and the boundaries.

List of games

 * Bit.Trip Beat: An orange paddle appears on the left side of the 3DS and will bounce back every incoming square back from whence they came. This squares are harmful for players so the inadvertly have to dodge them, they deal minimal damage and knockback, but the sqaures sometimes come in masses. Players can anticipate where the squares are coming through the top screen of the 3DS.
 * Mutant Mudds: Platforms come and rise from below, connecting to the blast lines on the left and right; these platforms come in segments thar are in different heights, and constantly change for the duration of this game.
 * Tetris: Axis: An grid appears and tetrominos drop down on the field. If it lands on a player, he/she will take some damage and good knockback. Some tetrominos are solid while other can be pass-through from below, but not from above; because of this, player may get stuck between the tetrominos with no possibility to escape. At the end, a straight Tetromino falls and fills the last gap, making every tetromino to disappear.
 * VVVVVV: Gravity is turned upside down and viceversa. The upper and low blast lines disappear so players cannot be KO'd from there and will simply continue falling or rising, after they reach the limits, they will instantly appear on the opposite site to resume the fall or rise and the game ends. Players can easily get Star KOd or self-destruct, if he/she is not careful as they may end up below the 3DS which cannot be traspassed and may hinder some recoveries.

Music
The stage's BGM is the original StreetPass Mii Plaza Theme 1 from the pre-installed 3DS application of the same name.

Origin
The Nintendo 3DS is Nintendo's sixth video game handhled console released in 2011 and is an autostereoscopic device capable of projecting stereoscopic 3D effects without the use of 3D glasses or additional accessories. This could be interpreted, somehow, as the player interacting with the games from a more real perspective thanks to the depth perseption. In SSF2, this goes ever farther to the point fighters actually interact with the 3DS that technically the games "come out" of the device, literally. The Nintendo 3DS was released worldwide in two different colours: Aqua Blue and Cosmos Black, with a third colour, Flame Red, coming several months later, In SSF2, the 3DS randomly changes its colour just as the battle has begun, but it's only for aesthetical purposes.

Bit.Trip Beat is the first installment of the Bit.Trip series, it is a arcade pong-esque game where the player controls a paddle whose job is to reflect incoming beats to gain score. This paddle is in SSF2 and reflects incoming squares that can harm the fighters.

Mutant Mudds is 2D platformer where the players must make use of the 3DS capabilities to jump out into the background or foreground, in order to over come obstacle and enemies and to proceed with the level. The platforms poping out from the bottom in SSF2 seems to be based on said ability for the players to change between background and foreground, considering some platfrm of the same kind are visible on the 3DS top screen.

Tetris: Axis is a puzzle game which makes use of the 3DS capabilities and offered a lot of game modes and special content. Virtually, there's no change in the Tetris formula, players have to fill every horizontal row to make the Tetrominos disappear. As Tetris: Axis is the original Tetris game for the 3DS, it appears on the 3DS stage where the tetrominos fall from above and plays like a normal Tetris game, though they actually work as platform an can land on players, damaging them.

VVVVVV is a 2D platform game, where player are unable to jump, but have to change gravity to vercome obstacles. The gravity changing mechanic is implamanted into SSF2 and characters continuosly fall and rise on the stage, there's a minimal difference, though: whereas in VVVVVV the player stands on the roof when the gravity is changed, in SSF2 fighters stay in the same position and can't stand under the 3DS, the only solid platform of the stage.
