Game Description:The blue dude with 'tude hits Nintendo DS for the first time with an all-new blast of high-speed hedgehog adventure. This time around, Sonic teams with a female partner in crime, Blaze the Cat, who's come from another dimension to help. They're up against a new arch-nemesis who's threatening not one universe, but two! The patented frenetic Sonic action sprawls across both DS screens, with super-high jumps, dizzying dives, monster loops, and insane curves. Play as Sonic or Blaze with differing storylines and outcomes. Bosses present more of a challenge than ever. They'll come at you from all directions on both screens!
