Sonic the Hedgehog has a new partner, Blaze the Cat, in this fast-paced platformer, Sonic Rush. You can play as either Sonic or Blaze as you try to track down powerful Sol emeralds. Sonic Rush displays the level over both screens, allowing for screen-spanning jumps and dives. Some gameplay modes include stylus support as well. Designed as a 2.5D side-scroller, Sonic Rush is the first game in the Sonic series to explore both 2D and 3D venues by combining two-dimensional environments with three-dimensional models. In 2007, the game received a sequel, Sonic Rush Adventure.
