Hint: Supply truck defense:
Do not enter the supply truck when it appears. Move back and forth to force the truck to collide with other vehicles.

Hints: Fork in the road:
Follow the left path when the road forks to find the oil supply truck. Follow the right side path to find missiles.

Hint: Driving the boat:
Stay to the right side of the screen during the boat sequences to lessen the amount of attacks and to reach the exit easily.
