The sewers are a maze of interconnected tunnels. Your primary objective is to find a way out, which often involves activating various water pumps or opening locked gates. The main threat here is the Hunter Gamma, a frog-like creature that can instantly kill you if it swallows you whole. Use the Shotgun or Grenade Launcher with Flame Rounds for quick dispatch. Look for the Sewer Map to help you orient yourself. There are several hidden nooks with valuable items, so explore thoroughly but cautiously. Be prepared for ambushes in the water.
