By New screenshots of Sega’s PSP racing game starring Sonic and Shadow reveal two more characters: Knuckles and Silver. Silver is one of the new hedgehogs in the PS3 / Xbox 360 Sonic the Hedgehog game. He’s from the distant future and has psychic powers instead of being able to run fast. I wonder how that is going to work out for Silver when he is trying to race to the finish line in Sonic Rivals.
