Walker survival in a prison, 1-4 players co-op. Hold the yard, fall back through the cell block, the cafeteria and the tombs as ammo runs dry. Hire a survivor if you need more backup. Then get everyone to the truck. Every run pays Scrip, win or lose. Spend it in the Commissary on permanent upgrades that get you deeper next time.
