First it was the bird flu. then it was the swine flu. guess what's next? that's right: the zombie flu. your objective in this game is to shoot and eliminate the zombie virus cells before they harm your red blood cells, or consume you. one way to do this is to bump them out of harm's way. the other way is to destroy the zombie viruses by moving over them. to help you do this, you can slow down the viruses or shrink them by shooting enzymes at them or by using freeze or time bombs. use wasd keys to move around. use your mouse to aim and click left mouse button to fire. press the spacebar to drop freeze bomb and press shift to drop time bomb. also, pick up as much rna (green spots) as you can to use on upgrades. have fun!
