Certain editions of the game were also packaged with the ability for online multiplayer gaming. Most Wanted brought in many notable improvements and additions over other entries in the series, its major highlight being more in-depth police pursuits. The game focuses on street racing-oriented game play involving a selection of events and racing circuits found within the fictional city of Rockport, with the game's main story involving players taking on the role of a street racer who must compete against 15 of the city's most elite street racers to become the most wanted racer of the group, in the process seeking revenge against one of the group who took their car and developing a feud with the city's police department. An additional version, Need for Speed: Most Wanted 5-1-0, was released in the same year for PlayStation Portable. Developed by EA Canada and EA Black Box and published by Electronic Arts, it was released on November 11, 2005, for PlayStation 2, Xbox, GameCube, Nintendo DS, Microsoft Windows, Game Boy Advance and Xbox 360. Need for Speed: Most Wanted is a 2005 open world racing video game, and the ninth installment in the Need for Speed series.
