Mario Tennis Open

Mario Tennis Open is a game in the Mario Tennis series for Nintendo 3DS. It is a successor to Mario Power Tennis originally released for Game Boy Advance. Announced just before the Tokyo Game Show in 2011, the game was released in North America on May 20th, 2012 and all other major regions by the end of the month.

Gameplay
The game utilizes the 3DS' gyroscope controls as well as the touch screen. It supports online player matches via Nintendo Network and offers a monthly leader board. Winning in an online match gives the player a "Victory Medal". What these Victory Medals will be used for is unknown. The game uses the StreetPass feature to allow players to engage in competitive StreetPass Matches or co-op Ring Shot challenges using ghost data of people they encounter. Players have the ability to upgrade their Mii's abilities with about 200 original items such as tennis rackets, outfits and costumes that feature different attributes and abilities. For example, by wearing a Yoshi costume, the Mii gains the speed of Yoshi. These can be unlocked either through normal playmodes or with QR Codes.

Special Games
Aside from the single and multiplayer modes, the game features four special modes. These are:

Characters
The game features 17 playable characters including Miis, each in one of six player classes. There are four hidden characters that are unlocked by completing certain challenges.

Yoshi Variants
Outside of the main character choices there are also 7 different colored Yoshis to unlock with QR Codes. These Yoshis have different stats than that of the standard green Yoshi. The QR Codes will be distributed over a course of time in a variety of ways. In the UK, a promotion entitled "The Yoshi Chase" involes the distribution of QR Codes to various stores and locations. The QR Codes are region locked, meaning there are different codes for each Yoshi in the major geographical regions.

Trivia
