Welcome to the Offroad Hill Climbing American Truck Simulator game. The aim of this game is to climb to the top of the hill by using your skills. To get started, you will have to choose from one of the available trucks, and then you will have to make your way up the hill. You will need to use the brakes and the gas to make sure that you are not going to lose control of the truck. 

When you are driving up the hill, you will have to keep an eye on the gas gauge. If it gets to the maximum level, you will have to stop driving and get out of the truck. You can also use the map to get a better idea of where you are and where you need to go.
