15 years ago . . .The world fell.Armies of the dead swept across the globe, toppling civilization and bringing humanity to its knees. Now, as the dead virus has ran its course and is fading away, those who survived face a new terror: the ever-growing numbers of the Sasquatch species.The Earth is an apocalyptic wasteland, survivors barely managing to make it day-by-day. Food is scarce, hope is hardly found.Yet all turns on a dime when a secret base is discovered underground and it is learned that it might hold the hope for victory in this deadly world.War breaks out, and this time man and machine combine as the struggle between humanity and the beasts wages anew to see who will hold the top spot on nature's food chain.
