Chapter 6: The Bait is the sixth chapter in the game Dark Sector. Walk towards the manhole cover and enter the Black Market to purchase any new weapons (you'll at least want a shotgun on this level. I recomend the Protecta). Once you exit from the Black Market, continue forward and fight a new enemy type: Stingers. You can pick up the Accuracy upgrade case inside the green army tent nearby, and you could utilize the nearby turret to help kill stalkers. Once you've defeated all of them, the doors to the nearby building will open. Ascend the stairs and go through the double doors.
