The sequel to Sonic’s 2D action platformer, exclusively developed for the PSP system, features a revamped rival jostling gameplay system for tighter head-to-head competition. A brand new Battle mode allows two players to jump into six different multiplayer challenges by sharing just one disc using the PSP system’s Wi-Fi function. Rivalry is further improved with upgraded power-ups and range weapons allowing players to attack or defend themselves regardless of their position. Additionally, card trading and collection in Sonic Rivals 2 has also been revamped with 150 more collectable cards enabling player to customize characters with new track suits, unlock PSP backgrounds, and unlock Cup Circuits.
