The following is an explanation to what causes the Zombie outbreak in "Zombie Nation":
The Z-Virus is the ultimate in Bio-Warfare. It has the ability to wipe out every human on the planet, like most Weapons of Mass Destruction, however, it was never meant to be used. WMDs are, after all, like having a friend that people are scared of. "Don't mess with him, his friends will beat you up." It keeps everyone relatively peaceful.
The Z-Virus infects humans in much the same way influenza does, that is to say it is carried through the air. Unlike influenza though, which can survive outside the body for a maximum of 48hours, the Z-Virus can survive a lot longer.
Once infected, you don't show any outward signs caused by the Z-Virus, inside though, it works away at your immune system. Breaking it down until it can no longer fight anything - opening you up to infection from the world around you.
The virus then waits.
It waits until you're at death's door. The white light is shining, voices are calling for you to walk towards it. It is then that the virus truly attacks. It ramps everything up into overdrive. Thirst, Hunger. You get your second wind, energy like you haven't seen since long before you were infected. Your brain, however, is all but shut down. It keeps everything ticking over, but it focuses everything on the hunger.
True death only comes when there's nothing left to feast on and by that time there's nothing left at all. Life, as we know it, is over.
Fish may still swim in the ocean, birds may fly in the sky. But the human race is gone.
I realise the above isn't exactly production news, but I figured getting an explanation to just how our zombies work would be a good thing.
In other news from the Scottish camp, if all goes according to plan, we've got a Jacob to go with our Molly. Grace depends on who plays Jack and that role is still up in the air just now.
That is all.
