Enemies are attacking your city, and they’re entering in monster trucks. To defend your city, you must destroy enough vehicles out of each wave of enemies. As they roll in, wreck the trucks by picking them up off the ground and slamming them back down as fast as you can. If the truck is not fully destroyed, you will see how much damage you did on its damage indicator, and you can pick it back up and smash it again. If you don’t destroy enough enemy trucks, they will take over the city and you lose the level. As you win levels, earn money and gain the ability to buy weapons like rocks, bombs and lightning.
