Featuring an all-star cast of characters from the amazing worlds of both Mario and Sonic, players will be able to compete as or against a range of familiar characters including Mario, Sonic, Luigi, Knuckles, Yoshi, Tails and more. Innovative usage of the DS control systems to maneuver your favorite character will allow players to race the likes of Mario and Sonic down the 100m track, leap over the high jump or churn water in a swimming heat, all while competing for the much sought-after Olympic gold medal. With up to four players on the DS, the stage is set to catch the fever this holiday with Mario and Sonic.
