Need for Speed: ProStreet is a 2007 racing video game developed by EA Black Box and published by Electronic Arts. It is the eleventh installment in the Need for Speed series and a follow-up to Need for Speed: Carbon (2006). Unlike its immediate predecessors, which focused on the contemporary illegal street racing scene, ProStreet focuses on legal circuit races that take place on closed tracks. The game blends elements of both sim and arcade racing games, requiring players to customize and tune cars for various race modes. Most races take place in real-world locations such as the Portland International Raceway, Mondello Park, and Autopolis.
