Chapter 8: Unnatural History is the eighth chapter in the game Dark Sector. The eighth chapter is much shorter than the previous one. There are no manholes here, but upgrades can still be found. From the starting point, begin fighting through the rooms and corridors filled with zombies. Take the Accuracy upgrade in the laundry room, which connects to the long corridor with the second wave of zombies. At the lobby area, kill the several mutants who show up. Work across the second floor, moving past the gun emplacement, and go down the stairs to the first floor.
