The historic sports action face-off of the video game industry now comes to the Nintendo DS™ in dual-screen glory with new DS-only features! Utilizing the Touch Screen and stylus technology, players will make their favorite characters - including Mario, Sonic, Luigi, Knuckles, Yoshi and Tails - run faster, jump higher and compete like true champions. Up to four friends can connect wirelessly and compete for the much sought after gold medal in actual Olympic events from track & field to swimming in the ultimate showdown between Team Mario and Team Sonic.

• Authentic environments and 16 Olympic events. Stages are modeled after reallife Olympic venues with actual Olympic events, including track & field, archery, and skeet shooting, as well as Olympic events exclusive to the DS, such as Cycling Pursuit and 10m Platform.
• Four unique playing styles. The competition takes on a new dimension with the special strengths and abilities of each character. For example: Sonic and Yoshi (Speed), Mario and Amy (All-around), Peach and Tails (Technical), Bowser and Knuckles (Power).
• Three game modes: In Single Match mode, players can try out each event individually, or compete for the highest overall score across multiple events in Circuit mode. In Mission mode, there are challenges created specifically for each character.
• Multiplayer challenges for four players. Players can join in the fun simultaneously via the Nintendo Wi-Fi Connection on the DS.
• Exclusive unlockable events. Familiar items from the worlds of Mario and Sonic enhance exclusive events for the DS, including Dream Basketball, Dream Boxing, Dream Cycling and more.
• Enhanced Touch Screen controls. Players can get their favorite character from Team Mario or Team Sonic to run faster, jump higher and compete like true champions with intuitive Touch Screen controls.
