A short history about NFS Heat

Need for Speed Heat is a racing game set in an open world environment called Palm City, a fictionalised version of Miami, Florida and its surrounding areas. The in-game map features diverse geography, including mountainous areas and open fields.[1] Unlike Need for Speed Payback, the game does not include a 24-hour day-night cycle, but players can switch between day and night. During the day, players can take part in sanctioned race events, which reward players with cash to spend on new cars and upgrades. During the night, players can take part in illicit street racing, which rewards REP. Racing during the night will attract the attention of a rogue police task force that patrols the streets of Palm City, who are tasked with shutting down street racing in Palm City which can lead players to risk their earned rep against the police or lose their earnings in handcuffs Pursuits in Palm City can take place during day or night, but the PCPD's response to a pursuit differs depending on the time period. Players earn rep from participating in pursuits, with great amounts offered during night than day. Each heat level also equates to the amount a player's earned rep for a current night session will be multiplied by, should they successfully reach a safehouse or garage.
