The Swine Flu epidemic hit in 2009. Doctors everywhere acted quickly trying to find a vaccine to prevent it from spreading. None of them were as effective as now. Become a doctor determined to fight off the swine flu the right way: by shooting down deadly pigs with a turbo-charged syringe gun. Fight them off by aiming with your mouse. Hold the left mouse button down to charge your syringe gun, then release to send it flying in the swine's' direction. Regular pigs are easy to keep at bay; but watch out for the sombrero-wearing pigs- hitting them from above won't do any damage. This is how you fight the swine flu.
