Normally, you don't want any harm to come into your car since you paid for it, but in times of war, you need all the things that you can use against your enemies. Besides the military will surely pay you and even give you a better car. You are one of the best stuntmen in the world and the country needs you.
The game is played via mouse and the idea here is to destroy as much enemies you can with the use of your vehicle. Run at full speed and detonate the vehicle when it is close to the enemies, so you can take them out.
