First, you were talking with soldiers. Next thing you knew, you were in a car with Ghost, driving full speed down the back roads. Somehow, a zombie apocalypse sprung out of nowhere, and half the people you knew were now infected.

How the hell did this happen? Well, it was plastered all over the news. A science experiment gone wrong.
