Navigating the murky Sewers in the Resident Evil 2 Remake presents players with several intense survival horror challenges, but few obstacles test your problem-solving skills like the Monitor Room chess plug puzzle. Unlocking the door to save your companion requires collecting six unique chess piece plugs scattered throughout the dangerous facility. Understanding the distinct configurations for both the First Run and Second Run scenarios is essential for making swift progress.

Finding all Six Chess Piece Plugs

Before attempting to arrange the plugs in the Monitor Room, you must first gather all six pieces from around the Sewers. The Pawn, Bishop, and Knight plugs are already located inside the Monitor Room socket panels when you arrive. However, retrieving the King, Queen, and Rook plugs requires exploring hazardous zones like the Supplies Storage Room and the Workroom.

Navigating the Supplies Storage Room involves a smaller multi-step plug puzzle where you swap the King and Queen plugs to unlock doors and obtain special weapons. Meanwhile, retrieving the Rook plug requires taking the Workroom lift up to the upper level and securing the item from a wall panel. Once all six plugs are safely in your inventory, you can return to the Monitor Room to begin decoding the clues.

Solving the First Run Scenario A Puzzle

For players tackling their initial playthrough on Scenario A, clues posted on the wall hint at the final placement of the pieces. The puzzle setup features two opposing walls with three wall sockets each. By analyzing the riddle, you can deduce that certain pieces must face each other directly while others remain on specific sides.

To solve the First Run configuration, face the wall panel layout carefully to ensure proper orientation. On the North wall (the left side facing the door), place the King, Queen, and Pawn plugs in order from left to right. On the South wall (the right side), insert the Knight, Rook, and Bishop plugs from left to right to unlock the door.

Solving the Second Run Scenario B Puzzle

Entering the Monitor Room during a 2nd Run playthrough introduces a completely altered set of clues and wall markings. The game intentionally trick-swaps several socket labels to catch experienced players off guard. Paying close attention to the revised note prevents wasted effort on incorrect combinations.

For Scenario B, the piece placements shift significantly across both wall socket sets. On the North wall (left side), insert the Knight, Rook, and Bishop plugs sequentially from left to right. On the South wall (right side), insert the King, Bishop, and Queen plugs from left to right to solve the mechanism.

Essential Survival Tips for the Sewers

Solving the chess plug puzzle is a major milestone, but managing your inventory while completing it is equally vital. G-Adult monsters infest the surrounding waterways, making resource conservation crucial during your retrieval runs. Carrying key defense items and healing herbs ensures you survive unexpected encounters while carrying heavy puzzle items.

Once all six plugs are inserted into their correct sockets, the heavy door opens immediately, allowing access to the facility's deeper sectors. Double check that you have gathered all optional items and weapon parts before proceeding past this point. Completing this puzzle smoothly sets you up for the thrilling final act of the campaign.
