Navigating the murky sewers in Resident Evil 2 Remake presents players with one of the game's most intricate brainteasers. To rescue Ada or progress deeper into NEST, you must collect six chess-themed plugs and insert them into the correct sockets inside the Monitor Room. Understanding where to find each key piece and how the combinations shift between scenarios ensures a smooth escape without unnecessary backtracking.
Where to Find All Six Chess Plugs
Three of the required pieces—the Pawn, Knight, and Bishop—are already located in the Monitor Room sockets when you first arrive. To obtain the remaining pieces, you will need to explore the surrounding sewer corridors thoroughly. The Rook Plug is retrieved from a wall socket near the Workroom lift, requiring you to access the lower waterway.
The King and Queen Plugs are hidden together inside the Supplies Storage Room. Solving a mini-puzzle involving gates in this area allows you to retrieve both pieces along with a powerful weapon. Once all six plugs are in your inventory, head back to the Monitor Room to begin setting up the final sequence.
First Scenario Chess Puzzle Solution
For players tackling their first playthrough (Scenario A), the puzzle note on the wall gives crucial hints regarding placement. Face the locked door with the main panel wall on your left and the opposite socket wall on your right. On the left wall, place the Knight, Rook, and Bishop from left to right as you move toward the back.
On the right wall, insert the King, Queen, and Pawn starting from the far end back toward the entrance. Double-checking each slot prevents simple positioning errors that keep the heavy door sealed. Once all six plugs align correctly, the electronic lock disengages instantly.
Second Run Chess Puzzle Solution
Entering the sewers during a 2nd Run (Scenario B) completely changes the required configuration. Although the physical locations of the plugs remain identical, the clue riddle provides entirely new instructions. The altered layout forces returning players to adapt their strategy.
For the left wall, arrange the pieces from left to right as King, Bishop, and Queen. On the right wall, place the Knight, Rook, and Pawn in order from left to right. Correctly placing these plugs unlocks the door, giving you access to the main power panel room.
Tips for Managing Sewer Hazards
Gathering all chess plugs requires traversing dangerous areas infested with G-Adult mutants. Carrying secondary weapons like grenades or knives helps you break free if grabbed in deep water. Equipping red and green herb combinations boosts your defense against poison attacks while retrieving the Supplies Storage Room items.
After completing the puzzle, remember that you can safely leave the plugs behind as they are no longer needed. Managing inventory space efficiently allows room for health items and ammunition required for the upcoming boss fight. Taking the time to prepare before powering up the door prevents costly restarts.
