Hellacious Acres: The Case of John Glass

John Glass wakes up in a desolate barn from a long cryogenic slumber, to be informed that not only has the planet been devastated by a third world war, but also reduced to little habitability by a subsequent alien invasion. He learns that in order to help reestablish a livable atmosphere for what's left of humanity, he'll have to go on a solitary mission to retrieve important codes dispersed throughout remote locations. Soon enough he'll encounter more than he "bargained" for: aliens, crazy survivors, inadequate equipment, LOTS of walking and a pretty unhealthy dose of bad luck...
