Sonic returns to the Nintendo DS with all the classic 2D, dual screen action the fans loved in Sonic Rush, as well as a new high-seas adventure where he clashes with ruthless pirates. As Sonic, players will set off from Windmill Village to explore seven action-packed levels featuring the classic 2D gameplay that the Sonic series is known for. Now players will get to explore the action stages to uncover valuable items and materials which allow Tails to build new ships that help Sonic track down the villainous pirates. With a fleet of up to five ships, including a submarine, water bike, and hovercraft, players will use the touch screen technology in exciting new ways to control their ships as they race across the ocean gathering rings, busting tricks, and torching pirate ships in fierce ship-to-ship battles. At the end of each level, players will test their skills in epic 3D boss battles that span both screens, including the ultimate showdown with the evil pirate, Captain Whisker. Let the adventure begin!
