Super Smash Bros. Ultimate

Super Smash Bros. Ultimate is the latest entry in the Super Smash Bros. series, releasing on the Nintendo Switch on December 7, 2018 everywhere. It includes all the characters and most stages from across the series.

Gameplay
The game mostly stays the same as Super Smash Bros. for Wii U though the game has been streamlined more for competitive play. This time, stage is decided before character selection. Damage is increased for one-on-one fights. Directional Air Dodges have returned but, dodging will be slower for increased use. Final Smashes have changed for a lot of characters with most becoming short cinematic finishers.

Assist Trophies have changed so that some of them can be attacked and KO'd. KO'd ones can earn points for the player that defeats them. There are over 50 different characters including cameos from third parties.

The game includes every character from across the series. Some characters which share the same moveset are moved to the same character slot as Echo Characters.
