Join this epic battle between the firefighters, emergency trucks and policemen! You can choose your team and then crash against the vehicles of your opponents until you destroy them. But avoid damaging your teammates, because they are actually helping you. Between levels you can buy new awesome cars, upgrade the ones you have or repair them and during the battle you can pick up power ups! See if you are really between the city's finest! Good luck!
