There's nothing more annoying than a paratrooper floating down from the sky. That's why in ParaShoot, you get the opportunity to kill them all. Use your mouse to aim and shoot all the paratroopers. You also get to shoot down the helicopters, but watch out for low health, because it's a killer. There are health boxes to increase your health. So get out there and start taking pot-shots at all those annoying paratroopers.
