The world as we know it ended on October 7th, 2011. There were few survivors as the virus spread to the four corners of the Earth. Those unfortunate enough to contract it joined the hordes of flesh-eating undead. It wasn't long before the dead outnumbered the living a hundred to one.
Shane and the rest of the survivors can't live off the museum forever. The food is almost gone; madness is beginning to set in. It's time to go outside, to search for some kind of life, to survive as best they can for as long as possible.
The frost has thawed....
This is the end of the line.
