The gloves are off and Sonic and his rivals are gearing up for an intense new head-to-head
competition exclusively on the PSP?(PlayStation?Portable) system.
This sequel to Sonic's 2D action platformer features all-new "jostling" controls
for tighter competition and a brand new Battle mode that allows two players to jump into
six different Multiplayer challenges by sharing one disc. With three new characters,
12 new stages and upgraded signature moves for each character, the enhanced Rivals experience
will bring a whole new level of handheld fun to the PSP system.
