Everything has fallen to the terrorists and you need to escape the city. You found a car that you can use to getaway. You know that this will be dangerous, but you don't have other options. It is escape the city or let your life be in the hands of the terrorists.
The car drives by its own. You just control the jump and the steer. You have a limited fuel. If you want to go faster than you are already running then you need to perform some stunts to activate the turbo. Grab some coins and gas as you drive along the road. You can use the money to upgrade your car or buy a new one.
