Nintendo has launched the website for Mario Tennis: Ultra Smash. While the site is bare, there is a banner that states that a full site will be coming soon. The site also tries its best to explain the uniqueness of Mega Battles, which allow players to grow large with a mega mushroom to dominate the court. You can also surprise your opponents with a new move to the series called the Jumpshot, which sends the ball flying down the court. You can check out more details by visiting the website, and remember, Mario Tennis: Ultra Smash is due out in North America and Europe on November 20th.
