In Mario Tennis Open, Mario and his Mushroom Kingdom friends return to the court for a flurry of intense tennis action, from engaging singles and doubles matches to skill-building Special Games and online play. Using the built-in wireless features of the Nintendo 3DS system, up to four people can play together in local* or online** multiplayer modes and exchange player information via StreetPass. Players can choose between intuitive Touch Screen and gyro sensor controls or strategic button-based gameplay that delivers an even deeper experience. Players can also choose from a variety of playable characters or use their own personalized Mii character as they serve, volley and smash their way up the leaderboards.
