The sequel to Sonic's fast and furious 3D action platformer, has several new features to enhance the player's experience. A revamped rival "jostling" gameplay system allows for closer head-to-head competition, whilst rivalry is further improved with upgraded power-ups and range weapons allowing players to attack or defend themselves regardless of their position. 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.

Miles "Tails" Prower and other new characters have been added to the mix of characters available to play as, whilst the new single player Free Play mode will allow players to enjoy every level in their own way. Each character in the game will also have their own unique signature moves that fit their varied personalities.

Card trading and collection in Sonic Rivals 2 has been greatly increased and will now include 150 collectable cards. This will enable players to customise character's track suits, as well as unlocking new PSP backgrounds and Cup Circuits.
