Your objective in this game is to work as a crane operator and move trashed cars, trucks and buses to the compactor. The trick is stacking the cars so that they don't fall over. During each level you are given a weight quota of vehicles to stack and a limited time to do it in. Aim carefully with the crane and try to stack the cars neatly - the neater the pile the more compact the final product will be (and the more points given). Once you have reached your quota weight, you must then operate the compactor directly to squash the vehicles into a small cube. Try to maximize the power settings for vertical and horizontal compaction to get the best result and score. Good luck!
