Navigating the dank and hazardous Sewers in Resident Evil 2 requires solving one of the game's most famous environmental challenges: the Monitor Room chess plug puzzle. Players must locate and arrange six distinct chess-themed electronic plugs to unlock the heavy door leading deeper into the facility. Mastering the exact configuration for both the first playthrough and the secondary scenario ensures a smooth escape without wasting valuable resources.
Finding the Required Chess Plugs in the Sewers
Before attempting to line up the plugs in the Monitor Room, players must gather all six pieces scattered across the subterranean map. While the Pawn, Bishop, and Knight plugs are already located in or near the main control room, the remaining three pieces require exploration. Retrieving the King and Queen plugs involves navigating the Supplies Storage Room, while the Rook plug must be collected from the upper hallway socket.
First Scenario Chess Piece Layout
For players tackling their initial playthrough (Scenario A), the wall sockets require a specific layout based on clues found on the nearby notice board. On the left wall facing the locked door, insert the Knight, Rook, and Bishop plugs starting from the far end closest to the door. On the right wall, align the King, Queen, and Pawn plugs from the far end moving backward.
Second Scenario Chess Piece Layout
Players jumping into Scenario B (2nd Run) will discover that the correct combinations change significantly. On the left wall, insert the King, Bishop, and Queen plugs starting from the far end near the door. Conversely, the right wall requires the Knight, Rook, and Pawn plugs placed in sequence from the back end.
Tips for Quick Solving and Inventory Management
Managing inventory space is crucial when carrying heavy key items like chess plugs through infested corridors. Always clear out unnecessary items in the nearby item box before embarking on retrieval routes. Double-checking plug placements against wall labels prevents redundant backtrack trips and saves valuable time during speedruns.
