Week 4 (2012)

From publisher blurb:

After taking control of a Federal prison and having it threatened from the inside by a serial killer, the characters were forced to abandon the safe haven altogether when Ragers made it into the facility.

Left with no supplies and inadequate protection against the winter elements, the group sought refuge within the Citizen Relocation Zone, which had been taken under control by unknown forces following an outbreak that all but decimated it.

Now, the CRZ facility is under attack by forces that have released the cordoned Living Dead. Meanwhile, the characters witness a change in the Living Dead that could once again alter the world.
