Mario Tennis: Ultra Smash

Mario Tennis: Ultra Smash is a video game in the Mario Tennis series developed by Camelot Software Planning and published by Nintendo for the Wii U, released internationally in November 2015, and released in Japan in January 2016. The game received mixed reviews from critics due to its lack of content.

Gameplay
Players are able to choose from 16 playable characters for use in 1-on-1 matches or 2-on-2 matches. There are power-ups that can give characters special abilities. The game does not require motion controls.

The game has a total of 4 modes: Mega Battle gives the players an ability to use the Mega Mushroom, which allows the player to have more power and better range; Knockback Challenge has the player facing challenging AI opponents; Classic Tennis allows players to change the rules such as "Chance Shots, Jump Shots and power-ups"; and the Online Mode allows players to team up with another player. Online play does not support friend-based matchmaking, only allowing matchmaking with other random players. Players can also use amiibo to play against other players.

Reception
Ultra Smash received "mixed" reviews, according to video game review aggregator Metacritic.

IGN's Marty Sliva gave the game 4.8 out of 10, calling it "a bare-bones, lackluster addition to Mario's sporting adventures". He also compared it unfavorably to its predecessors by stating "that Mario Power Tennis on the GameCube managed to include more characters, interesting modes, and varied courses a decade ago is a bit insulting." GameSpot's Scott Butterworth similarly criticized the lack of game modes and alternate ways to play and awarded the game 6 out of 10. Nintendo World Report's Daan Koopman lambasted the game for having "just one stadium, limited online options and less features than the previous 2 entries."

In its first week of release in Japan, it sold 55,331 units, which made up 80% of its initial shipment.
