But building structures alone isn't enough this time: you sit behind the wheel of the vehicles yourself and have to maneuver them skillfully to the goal. Collect stars, complete daredevil jumps, flips and spectacular stunts, leaving behind a trail of destruction across the entire level to beat the high score. But you can only do all that with perfectly constructed bridges and ramps.

Let the world be part of your most outrageous jumps! Improved Construction Mode Once again you have access to a variety of building materials with different properties. Numerous improvements make building even easier: simply tap to convert a beam you have built into road, and vice-versa. Tap and hold on a part of the construction and you now have the option to reposition your structures without having to build them from scratch. Loose Screw! We have hidden some hard-to-reach screws in some of the levels. Find and collect them, and you might be able to put these screws to good use in the future...
