Game will be mission based so that you get to do a series of short mission that include various aspects of police work (including traffic stops, pursuits, arrests, gun fights etc.)
Originally the idea was to do an open world game where player could freely roam around the city and do patrols much like in LCPFFR, but this idea has been since dropped as doing an open world game will take too much time and resources. Open world game mode is something that can be reconsidered once the intial game has been released (e.g, as a separate game mode).
