Navigating the murky sewers beneath Raccoon City in Resident Evil 2 presents some of the game's most intense survival challenges. To rescue Ada or progress toward the NEST laboratory, players must collect six chess-themed plugs and arrange them correctly in the Monitor Room. Understanding where these crucial key items are hidden saves precious ammunition and avoids deadly encounters with sewer mutants.
Locating the Initial Chess Plugs
When you first arrive at the Sewer Monitor Room, three plug pieces are already inserted into the wall sockets. The Bishop, Knight, and Pawn plugs are available right away, but you must collect the remaining three to solve the door lock. Keeping track of which sockets are occupied helps avoid unnecessary back-and-forth travel through dangerous corridors.
Many players consult daily gaming news and puzzle guides when navigating these intricate sewer pathways. Having a clear plan minimizes your exposure to G-Adult creatures lurking in the murky water channels below. Efficient inventory management is essential before heading out to retrieve the missing pieces.
Finding the King and Queen Plugs
The King and Queen plugs are located together inside the Supplies Storage Room in the Lower Sewers. Reaching this area requires traversing the Bottom Waterway, where heavy enemies guard the narrow paths. Inside the storage room, you must complete a mini-puzzle by swapping the two plugs between specific doors to open locked gates and secure the Chemical Flamethrower or Spark Shot.
Once you grab both items and the specialized weapon, carefully retrieve the plugs behind you so you do not leave either piece locked inside. Navigating back through the storage room gates in reverse order ensures you escape with both the King and Queen plugs in your inventory. Taking your time here prevents backtracking later in the run.
Retrieving the Rook Plug
The Rook plug is located in the Upper Sewers near the Workroom lift. To access this area, use the Sewer Key on the Water Injection Room or move through the Treatment Pool Room. You will see the Rook plug inserted into a wall socket along the hallway socket panel.
Pulling the Rook plug out of the wall immediately raises the nearby gate, so make sure you have cleared the area of zombies first. Once collected, you will have all six chess pieces required to solve the final Monitor Room puzzle. Return to the central hub to begin alignment.
Solving the Monitor Room Wall Socket Puzzle
The arrangement of the plugs differs depending on whether you are playing the First Scenario (Scenario A) or Second Scenario (Scenario B). In Scenario A, face the wall with the main door and place the Knight, Rook, and Pawn on the left wall, while placing the King, Bishop, and Queen on the right wall. Matching the subtle wall mural clues or environmental hints confirms the correct placement.
In Scenario B, the order changes to reflect a altered layout challenge. The left wall requires the Queen, Bishop, and King, while the right wall takes the Knight, Rook, and Pawn. Once all six pieces sit in their correct sockets, the heavy blast doors unseal, allowing access to the facility power room.
