Game Description:Sonic's newest rush comes riding on the high seas in this new adventure for Nintendo DS. Hit the waves and get ready to chase down a rascally band of pirates in 14 levels of classic 2D Sonic gameplay. Explore a string of islands, where you'll collect materials and turn them over to your trusty sidekick, Tails. You'll use hovercrafts, water bikes, subs, and more as you rack up rings, master new tricks, and torch pirate ships in explosive battles. Two players can go head-to-head in two-screen races or mission-based battles.
