In the remake of Resident Evil 2, navigating through the gloom of the Raccoon City Sewers culminates in a central puzzle involving chess-themed plugs. Players must locate and correctly arrange six specific pieces—King, Queen, Rook, Bishop, Knight, and Pawn—to unlock the door to the Garbage Room and advance the story. Mastering this task requires a clear understanding of where each piece is hidden and how the socket clues match up in different story scenarios.
Locating the Queen and King Plugs
The Queen and King plugs are retrieved together inside the Supplies Storage Room in the lower level of the Sewers. Navigating this area requires dodging dangerous G-Adult mutants while managing limited ammunition and herbs. Once inside the room, players must swap the two plugs between various sockets to clear locked gates and ultimately obtain the Chemical Flamethrower or Spark Shot alongside both chess pieces.
Finding the Rook Plug and Exploring Upper Levels
To acquire the Rook plug, head toward the Workroom Lift located past the Lower Waterway. Taking the lift up brings you to the Workroom, where the plug can be pulled directly from its wall socket in the hallway. Collecting this piece is essential, though removing it prematurely may raise water bridges, so timing your movement carefully through the corridor ensures you do not get trapped.
Understanding Scenario Differences and Socket Clues
Solving the Monitor Room puzzle depends heavily on whether you are playing Scenario A or Scenario B. Etched wall panels and notes left near the sockets offer crucial hints about which chess piece belongs opposite another. For instance, in Scenario A, the Knight, Rook, and Bishop line up differently compared to the Second Run scenario, making it vital to read the surrounding wall plaques carefully before placing the pieces.
Placing the Plugs and Unlocking the Door
Once all six plugs are in your inventory, return to the Monitor Room to begin final placement. Align each piece according to the specific wall diagrams provided for your current playthrough. Inserting all six chess plugs into their correct sockets restores power to the main door, allowing players to rescue their companion and prepare for the upcoming boss encounter.
