First it was the bird flu. Then it was the swine flu. Guess whats next? Thats 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 harms 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.
