Mario Tennis Ultra Smash has been announced for the Wii U during today's E3 Digital Event.

A short trailer was presented, showing our familiar heroes and villains using an Ultra Mushroom on court to grow and gain the upper hand on court. It also features a new jump smash shot to use to beat your rivals. Like the rest of the series it is developed by Camelot, and will allow you to play with up to four players in doubles and singles matches. There was no mention of whether online multiplayer will be featured. Take a look at what was shown below.

The game will release in Q4 2015. We'll have more details for you in due course.
