Super Smash Bros. Ultimate

Super Smash Bros. Ultimate (大乱闘スマッシュブラザーズ SPECIAL) is a fighting video game developed by Sora Ltd. and Bandai Namco Games and published by Nintendo, with a planned release for the Nintendo Switch on December 7, 2018. It is the newest installment in the Super Smash Bros. series; because game director Masahiro Sakurai considers the previous two titles the fourth and fifth installments respectively (despite both having identical names with the same amount of playable characters and almost similar content) Ultimate is generally considered to be the sixth installment. The game was first teased during Nintendo's Nintendo Direct March 2018 presentation and was later formally announced at their Direct presentation for E3 2018.

Like the rest of the series, Super Smash Bros. Ultimate is a crossover non-traditional fighting game where players use different attacks to weaken their opponents and knock them out of an arena, and the game features characters, items, music and stages from various Nintendo franchises as well as from third-party franchises, including Street Fighter. Ultimate is notable for adding every single playable fighter from previous titles, including cut characters and downloadable characters.

Gameplay
Ultimate is a non-traditional fighting game in which players use different attacks to weaken their opponents and knock them out of an arena. It features a crossover cast of characters from several different Nintendo franchises, as well as from third-party properties. Ultimate includes all characters from all previous Super Smash Bros. games, including those previously released as downloadable content, as well as some new characters, bringing the total roster of playable characters to over 68, the highest number of characters in any Super Smash Bros. game in the series' history. Because of the high number of playable characters, there will not be many newcomers as usually expected by fans. Additionally, some characters who were previously alternate color scheme or regular fighters are now known as "Echo Fighters" ; these fighters have identical or similar movesets to other characters. For instance, Princess Daisy from the Mario franchise, who previously inspired a costume for Princess Peach in prior Super Smash Bros. titles, is an individual Echo Fighter in Ultimate. Several of the characters have received updates to their outfits, such as Mario having Cappy from Super Mario Odyssey accompanying him, and Link shown in his outfit from The Legend of Zelda: Breath of the Wild. Others have been updated or new moves and abilities. Players will not have access to all characters on starting the game, and will need to unlock them by completing various challenges in-game; Nintendo anticipates making it easier for players to unlock all of the game's characters compared to previous games.

The game will have vast compatibility with controllers, including compatibility with the GameCube controller through the GameCube Adapter for Wii U. The game will also support existing Amiibo figures (including ones not necessarily related to Super Smash Bros.) for any of the fighters to provide unique abilities when used with the Joy-Con NFC sensor. The game will also feature many returning stages from previous games, as well as new stages. Several new characters have also been added as non-playable Assist Trophies, these include iconic third-party characters such as Konami's Bomberman.

Connection to Street Fighter series
As Ultimate includes every single fighter from previous titles, Ryu appears as a returning character. The Suzaku Castle was also seen in the gameplay videos. The official site of the game also features in the music section new soundtracks, such as a exclusive version of Vega's Theme.
