Use your mouse to aim and shoot to destroy as many pigs in planes as possible by clicking to cause a chain reaction. This gets you cash! Reach the red flag in the progress meter to clear the level. The charge meter will refill as chain reactions occur. When full, roast 'em again! Get stars by colliding with them or via the kill progress meter. Stars unlock new upgrades. You can always sell upgrades if it is makes a level hard! See how many of the more than 30 levels you can get through and have fun playing Kamikaze Pigs!
