Find the Black Files, or humanity falls.

Alex never thought he'd be recruited for a mission to save humanity. He's learned a lot since leaving Bunker 108, but the horrors of the Wasteland aren't through with him yet.

When the team risks everything to go after the Black Files, there's no going back. The Great Blight will prove the toughest obstacle yet, with nearly impassable terrain guarded by the virus's spawn.

Alex and the crew must battle for their lives at every turn. Can they make it to Bunker One, and will the Black Files reveal how to stop the xenovirus?
