NFS: ProStreet follows aspiring "Street King" Ryan Cooper, who rolls up in his Nissan 240SX on race day determined to become champion of every event on the circuit. The journey kicks off with the Battle Machine race day, and as you rack up victories you advance through ever-bigger showdowns — earning a sponsorship from Super Promotion to compete at the Showdown at Chicago Airfield, then moving on to R3act Team Sessions and beyond. Along the way you shatter records, rake in cash, win parts, and unlock new cars on the road to becoming the ultimate street champion.
