"Need for Speed: ProStreet is the 11th installment of Electronic Arts' popular racing game series Need for Speed. On May 21, 2007, Electronic Arts published a teaser trailer of ProStreet, and officially announced it ten days later. It was released worldwide in November 2007. Its action footage was used in American Le Mans Series. ProStreet was the first PlayStation 3 game with DualShock 3 rumble support.
Need for Speed: ProStreet has taken the series in a different direction of gameplay. All racing in ProStreet takes place solely on closed tracks, making ProStreet the first game in the series since Need for Speed II that doesn't animate illegal racing. Rather, the type of racing appears to be Clubman Racing. The performance tuning feature is enhanced, compared to previous versions, especially Autosculpt. Unlike Carbon, where only certain body kits can be autosculpted, this can now be applied to all body kits, including stock bumpers and wide body kits. Furthermore, some adjustments through autosculpt impact the car's aerodynamics.
In ProStreet there are four different game modes: Drag (a race in a drag strip, point to point), Grip (similar to Circuit races but with four different types of Grip races available), Speed (similar to a Sprint race) and Drift."
