Navigating the tense corridors of the Raccoon City Police Department requires quick thinking and resourcefulness. Surviving the biological outbreak becomes significantly easier when you can unlock supply containers scattered around the map. Knowing every combination allows players to bypass long detours and gather valuable ammunition and upgrades quickly.

Unlocking Every Police Station Locker

Players will encounter several dial locks blocking access to critical inventory items during their playthrough. The third-floor hallway locker can be opened using the combination DCM to receive high-tier ammunition. Opening this locker early provides a helpful firepower boost for both Leon and Claire campaigns.

Another vital dial lock is located in the second-floor shower room. Cracking this puzzle requires the code CAP, which rewards the player with standard shotgun or submachine gun rounds. These supplies are crucial for clearing out regular zombies blocking narrow hallways.

Opening the RPD Office Safes

The West Office on the first floor contains a large safe holding an essential inventory upgrade. Entering the sequence Left 9, Right 15, Left 7 pops the door open instantly. Inside, players will discover a coveted Hip Pouch that expands their carrying capacity permanently.

Over in the second-floor Waiting Room, another heavy safe requires a precise combination. Turning the dial Left 6, Right 2, Left 11 opens the mechanism smoothly. Successfully cracking this safe grants Leon a muzzle brake for his handgun or Claire a high-capacity magazine.

Cracking Leon Desk and Sewers Puzzles

Leon desk in the West Office is secured by two separate letter locks that require clues from nearby desks. Inputting NED on the left side and MRG on the right side opens the drawer completely. This reveals a high-capacity magazine upgrade for Leon or a quick reloader for Claire.

As the story progresses into the Sewers, players encounter the final dial lock and safe puzzles. The Treatment Room locker opens with the letters SZF to give players extra heavy weapon ammunition. Nearby, the final safe can be cracked using Left 2, Right 12, Left 8 to claim an advanced weapon modification.
