Navigating the post-apocalyptic hazards in Dying Light The Beast requires both quick combat reflexes and sharp puzzle-solving skills. During the Hydro Puzzle side quest, players are tasked with investigating water supply issues, leading them directly into hidden sewer locations and locked administrative offices. Unlocking the safes scattered throughout this quest provides essential story items and high-tier equipment that make surviving Castor Woods much easier.
Locating the Hydro Puzzle Office Safe Code
As you progress through the initial stages of the Hydro Puzzle quest, your objectives will lead you inside the Waterworks Repair Facility to locate the Chief Engineer's key. The first safe sits directly on a desk inside the Payroll Manager office within the facility. To unlock this safe, players need to enter the combination 27 1 15 to retrieve the Chief Engineer's Key alongside valuable bonus items.
Navigating the Sewers for the Maintenance Safe
After securing the initial keys, the quest directs players deeper into the sewer maintenance tunnels beneath Old Town. Following yellow utility pipes will guide you through narrow crawlspaces and past hostile infected threats.

Finding the Hidden Sewer Combination Note
To open the second safe hidden in the sewer section, players must destroy wooden obstacles blocking a small vent entrance. Crawling through this hidden passage leads to a small room containing a note titled Debt Repaid placed on a shelf. Shinning your UV flashlight onto the surrounding surface reveals the secondary safe combination code 21 69 35.
Claiming Quest Rewards and Final Tips
Returning to the sewer safe and entering the code 21 69 35 completes the puzzle requirements and unlocks your hard-earned loot. Finishing the entire Hydro Puzzle mission grants substantial character experience, crafting manuals, and protective gear to aid your journey. Paying close attention to environmental hints ensures you never miss a hidden combination while exploring new zones.
