Which Nintendo Switch game in the series was released on December 7, 2018?

Super Smash Bros. Ultimate was the Nintendo Switch game in the series released on December 7, 2018.

Nintendo announced the game for Switch in March 2018, initially showing only a brief teaser during a Nintendo Direct. Its full title and release date were revealed at E3 in June, where Nintendo also emphasized that every previous playable fighter would return.

Ultimate followed Super Smash Bros. for Nintendo 3DS and Wii U, released in 2014. It retained the series’ platform-fighting format: players build up opponents’ damage and launch them from the stage rather than depleting a traditional life bar.

A common mix-up is treating Ultimate as the series’ fifth or sixth installment. Nintendo generally counts the 3DS and Wii U versions as separate games, while many summaries group them together. Melee was the GameCube entry, Brawl was made for Wii, and the 2014 title was not the Switch release.
