Living in the city might make you think that you can conquer the world because of all the hardships that you have gone through. However, you might be tough in your own backyard, but things is tougher somewhere. You need to explore all, so you can make the comparisons. For example, those buses on the road might make you think that they are the biggest and the baddest on the road. But, surely, you haven't seen all the vehicles yet because that massive vehicle can't be a much for the monster truck. It is rarely seen on the city because of its huge body and wheels. It is seen most of the time on the mountain, but every mountain doesn't have one of those trucks.
Drive your truck as fast as possible till you reach the finish line. Your goal is to reach the finish line in the least possible time. Actually, this game doesn't have any timer and you can finish it whenever you want, each passing second the points that you will get dwindle. So, basically, you need to get to the finish line as fast as you can. The game gets harder as you make some progress.
