Super Smash Bros. Ultimate is a 2018 crossover fighting game developed by Bandai Namco Studios and Sora Ltd. and published by Nintendo for the Nintendo Switch. It is the fifth installment in the Super Smash Bros. series, succeeding Super Smash Bros. for Nintendo 3DS and Wii U (2014).

The game features a roster of over 80 playable characters, including characters from Nintendo games, third-party franchises, and guest characters from other video game series. Players battle each other on a variety of stages, using a variety of attacks and special moves. The goal of the game is to knock the other players off the stage.
Super Smash Bros. Ultimate has been praised for its large roster of characters, its variety of stages, and its extensive single-player content. The game has also been a commercial success, selling over 25 million copies worldwide.
Nintendo first teased Ultimate in a Nintendo Direct in March 2018 and fully revealed it at E3 2018 the following June. It later received two additional Directs before it was released on December 7, 2018. The game received universal acclaim, with some critics calling it the best of the series. They praised its amount of content and fine-tuning of existing Smash gameplay elements, although its online mode received criticism. Ultimate is the best-selling fighting game of all time, having sold over 30 million copies as of March 2023, is a popular competitive fighting game, and has commonly been ranked as one of the best fighting games ever made, as well as one of the greatest video games of all time. The game received downloadable content adding new fighters, stages, and other content from its release until October 2021.
Multiplayer
The game supports local multiplayer, local wireless with other systems, and online play via Wi-Fi or LAN connections. By defeating players online, players can earn tags which can be traded for in-game currency to buy new spirits, music, and Mii Fighter costumes. The game is compatible with Joy-Con controllers, the Nintendo Switch Pro Controller, and GameCube controllers via the use of a USB adapter. Like in the previous entry, amiibo figurines can be used to create AI-controlled Figure Players that can be trained to become stronger. Sometime after the game’s release, a service for the Nintendo Switch Online mobile app, known as “Smash World”, was launched, which allows players to check their game statistics in addition to sharing images and videos captured from the game to social media.[
