A nuclear missile carrier is out of control, and unless the path is cleared, it will explode as soon as it makes contact destroying the world. It is up to you to clear the path so that nothing gets in the way of the carrier.

At the start of each level you are given a certain vehicle (ranging from robotic suits, trucks or bulldozers), and a time limit is set (the time you have before the carrier reaches the area that you are in. If any buildings still stand in the way, you lose).
