Chapter 7: Industrial Evolution is the seventh chapter in the game Dark Sector. The seventh chapter, like the fourth, is very lengthy and ends with another boss. There is a manhole at the starting point. The new weapon available for sale is the Korbov TK6. It's the best assault rifle, with better firepower and accuracy than the AKS-74, but it's very expensive. At the long corridor ahead, kill lots of zombies. Next, at an area that winds under some high elevated tracks, face another batch of mutants and zombies.
