The sequel to Sonic’s fast and furious 3D action platformer Sonic Rivals, Sonic Rivals 2 has several new features to enhance the player’s experience. A revamped rival “jostling” gameplay system gives Sonic Rivals 2 closer head-to-head competition, whilst rivalry is further improved with Sonic Rivals 2's upgraded power-ups and range weapons, allowing Sonic Rivals 2 players to attack or defend themselves regardless of their position. Sonic Rivals 2's brand new Battle mode allows two players to jump into six different multiplayer challenges by sharing just one Sonic Rival disc using the PSP system’s Wi-Fi function.
