In order to find the King and Queen plugs, players must head to the Supplies Storage Room in the Lower Sewers. However, finding all three of the missing pieces requires solving a puzzle of its own. Three must be obtained (King, Queen, and Rook) and then inserted in the correct order on the wall by the already-placed Bishop, Pawn, and Knight. To proceed through the monitor door in Resident Evil 2 Remake's Sewer, players must first find all of the missing chess plugs. One of the more complicated puzzles, Chess Plugs, can be extremely difficult without a guide, especially considering that some of its steps vary depending on which playthrough a player may be on.
While some are relatively straightforward, most require significant thought and effort to solve.
While the remake's story is not exactly like the original game, there are numerous puzzles that must be solved in Resident Evil 2 Remake, just like in the original.
