Super Smash Bros. for Nintendo 3DS / Wii U

Super Smash Bros. for Nintendo 3DS and Super Smash Bros. for Wii U are both versions of the upcoming fourth installment of the Super Smash Bros. series being developed by Sora Ltd. and Namco Bandai Games. Each version has a different release date due to the time that it will take to finish each one. The 3DS version will come first, scheduled for a Summer release, with the Wii U version coming out for a Winter release.

Gameplay
It has been confirmed that the Final Smash and Footstool Jumping features are returning from Super Smash Bros. Brawl, while the "tripping" mechanism has been removed and the game's Adventure Mode will be significantly different than the Subspace Emissary. It has also been stated that players will be able to send customized fighters from one version to the other, that attacks will be customizable , and that the pace of battles will be in between Super Smash Bros. Melee and Super Smash Bros. Brawl. Other elements have also been confirmed to connect the two versions of the game, though what these are is currently unknown. The game will not make use of the touch screen controls that both systems support during gameplay.

Smash Run
A new mode, Smash Run, has been confirmed to be a Nintendo 3DS-exclusive mode, strongly resembling the City Trial mode from Kirby Air Ride while including elements of the Subspace Emissary mode from Super Smash Bros. Brawl. In this mode, players travel in a large maze-like map, fighting enemies from both Nintendo games and from Super Smash Bros. games, such as Magikoopas, Chandelure, Goombas, Shy Guys, and Kremlings. While fighting, players can collect several items similar to patches. These patches can increase attack power, special attack power, jumping, or movement speed. After five minutes, players are shown the stats of their attacks, courtesy of the patches they collected, and they are pitted in several modes, similar to the Stadiums from City Trial. The players then must fulfill certain conditions to win the game.

Online Play
Both versions of the game are to feature online play similar to Super Smash Bros. Brawl in that players can face others in matches from around the world. In the Wii U version, when playing with friends, players can customize the rules to their liking. When not playing with friends, two basic modes are available for play: For Fun and For Glory. In For Fun mode, players can battle on any of the stages except Final Destination with any rules, the stages being picked at random; only victories are recorded in this mode. In For Glory mode, players can only play on the "Final Destination" versions of stages. One-on-one matches are possible in this mode, and both victories and losses are recorded.

In addition, rather than have an online leaderboard, a different type of ranking system is to be implemented, called "Global Smash Power." When playing in single player, the player's score determines their Global Smash Power, which is used to determine how strong the player is compared to others around the world.

Playable characters
Due to limitations with the Nintendo 3DS version of the game, certain characters from the previous installments in the series might be cut from the rosters of both versions in order to keep them consistent. So far, 29 characters have been confirmed, consisting of 23 veterans and 6 newcomers. Unlike previous games in the series, with the removal of in-game transformation, Sheik, Zero Suit Samus, and Charizard are now standalone characters.

Stages
According to Masahiro Sakurai, both versions of the game will feature different stages. The Wii U version will mostly feature stages based on games released on home consoles, while the 3DS version will mostly feature stages based on games released on handheld systems. In the Nintendo 3DS version, each stage has only two tracks that can play, whereas the Wii U version will have a comprehensive list similar to My Music from Super Smash Bros. Brawl. Additionally, most of the stages in both versions feature a "Final Destination" variation in addition to the normal one, being a flat course with no obstacles or other platforms.
