Upon entering the Sewers, your primary goal is to restore power and open the path forward. You'll need to collect three Chess Plugs: King, Queen, and Bishop. The King Plug is found in the Monitor Room. The Queen Plug is located in the Treatment Pool Room, requiring you to drain the water. The Bishop Plug is in the Supplies Storage Room. Be wary of the G-Adults, grotesque creatures that lurk in the water. Use the Chess Plugs in the Monitor Room to open the path to the Lower Waterway. Remember to check the map frequently for unvisited areas and item locations.
