The Mario Party-esque adventure mode in Mario Tennis Aces appeared in a trailer earlier this week. Nintendo has since published an English version explaining the features in the adventure mode, which is designed to be a solo training ground of sorts.
The adventure mode basically pits you against "the legendary racket", Wario and, of course, Waluigi. There's boss fights and basically a range of Virtua Tennis-style minigames, for those who miss that game dearly.
Nintendo this week also provided more specifics around the pre-launch online beta, which starts at 0000 AEST June 2 and runs until 0900 AEST June 4.
Mario Tennis Aces launches on June 22.
