Nintendo have just revealed some new information about the upcoming Mario Tennis Open.

Some of these new features include a ‘Special Features Mode’, new StreetPass features and special QR codes. Here are some specifics of the things that  Nintendo has revealed.

Online Play: Mario Tennis Open players can compete and cooperate in
local wireless matches with other opponents and play exhilarating games.
Players can also build up their Open Match standings, check the monthly
leaderboard and win Victory Medals from every challenger they defeat.

Ink Showdown: In this fast-paced competition, Piranha Plants spit ink
balls from the back edge of the court. Players must destroy the ink
balls before they splatter, while hitting tennis balls away from an
opponent.

StreetPass Features: Players can inspire friendly competition by
using the Nintendo 3DS system’s StreetPass feature. They can engage in
competitive StreetPass Matches or cooperative Ring Shot challenges with
computer-controlled versions of people they encounter and share their
StreetPass winning streak. StreetPass can also be used to show off
players’ Mii characters, which can be customized with new outfits and
accessories that can improve their on-court performance. As users play,
new items for their Mii will be unlocked in the Item Shop.

Unlockable Characters: New and familiar Nintendo characters can be
unlocked – some through game play, others via special QR Codes.
Unlockable characters include Luma, Baby Mario and Dry Bowser.
