A week has passed since the outbreak.

The last couple of days reports coming from the Emergency Broadcast System described a quarantine zone: a 150 mile radius circle centered on Dead Valley.

Centered on your farmhouse.

The National Guard is urging any survivors to head for the perimeter.

You've been holed up for a week and getting sick of eating beans. The walkers are getting closer ever day. If they figure out you're here the barrier you've slapped together will not hold.

Time to make a break for it. Drive 150 miles to escape from the valley!

You have three days before they cover the entire valley in napalm.
