The world's most famous hedgehog returns to the PSP in Sonic Rivals 2. Like its predecessor, Sonic Rivals 2 features 2D side-scrolling platform action set within 3D worlds. The story involves the Chao disappearing at an alarming rate, and it's up to the rivals to solve the mystery. A new emphasis has been placed on the Battle mode, which gives players six ways to take on their friends with only one game disc. Each of the eight playable characters have upgraded signature moves, including new entries Miles "Tails" Prower, Espio the Chameleon, and Rouge the Bat. Solo gamers can head through each of the 12 levels, and two players can use the PSP Ad-hoc wireless connection to participate in modes like Knockout, Ring Battle, Capture the Chao, and Tag. Gamers can collect up to 150 trading cards and use them to upgrade their characters or bet on Battle mode matches.
