The use of vehicles in an explorable urban environment provides a basic simulation of a working city, complete with pedestrians who generally obey traffic signals. Further details are used to flesh out an open-ended atmosphere that has been used in several other games, such as The Simpsons: Hit & Run, which has less emphasis on crime or violence, and Lego City Undercover, which reverses the roles of police officer and criminal, although the player goes undercover in gangs for a portion of the game.
