Description: 1st it was the bird influenza. Then it was the swine influenza. Guess what's next? That's right: the zombie influenza! You're an white blood cell. Your must protect the red blood cells. One way to do this is to bump them out of harm's way. The other way is to demolish the zombie viruses by moving over them. To help you do this, you are able to slow down the viruses or shrink them by shooting enzymes at them or by applying Freeze or Time Bombs. Also, pick up as much RNA (green spots) as you are able to. There are three types of zombie virus: Dissolver (looks like an mouth): Destroys red blood cells; must be shrunk before they can be eliminated; can also shrink you and make it temporarily impossible to shoot Eater (looks like a veiny eyeball): Grows by consuming red blood cells Spreader (looks like a black and yellow ball): Turns red blood cells into zombi viruses
