In Dying Light 2, survival relies heavily on upgrading your core physical capabilities to match the evolving threats of Villedor. Inhibitors are the primary resource needed to boost your maximum health and stamina, allowing you to access advanced parkour skills and survive brutal zombie encounters. Many of these invaluable upgrade canisters are locked away inside secure containers that require players to track down hidden riddles or combinations scattered throughout the post-apocalyptic cityscape.

Cracking the Early Game Safes in Old Villedor

Your first major encounter with locked progression containers typically happens during your early explorations of the Houndfield district. Inside a prominent night runner hideout located inside an old church tower, players can spot a secure lockbox containing a vital inhibitor. Finding the correct combination requires reading a nearby note, which reveals the solution to be 1-0-1 to quickly unlock the container.

Another early opportunity presents itself during the side quest involving the missing medical supplies at the local hospital outpost. A specialized storage safe sits quietly inside the main office floor, challenging players with a mathematical puzzle left behind by the doctors. Entering the solution 9-7-3 grants immediate access to the bio-markers and upgrade materials stored safely inside.

Navigating the Corporate Towers of the Central Loop

As you progress into the sprawling skyscrapers of the Central Loop, the environmental challenges and lock mechanisms become significantly more complex. A highly sought-after container rests near the top floors of the massive Downtown Electrical Station, surrounded by dangerous electrical hazards. The solution code is hidden within a nearby discarded artifact log, directing survivors to input the combination 3-1-4 to crack the lock mechanism.

Further exploration into the Garrison district brings players toward the towering VNC Tower structure, which features multiple hidden caches along its vertical architecture. A specific lockbox is hidden inside a secret apartment room just below the roof access point, requiring careful parkour maneuvering to reach safely. Aspiring night runners must input the numbers 6-6-6 to unlock the terminal and claim the powerful upgrades waiting within the vault.

Solving Muddy Grounds and Garrison District Riddles

The southern districts of the map contain unique environmental puzzles that tie directly into the historical lore of the urban quarantine zones. Within the Muddy Grounds region, an abandoned military container can be found hidden beneath a collapsed bridge infrastructure. The note nearby references a classic historical date riddle, leading players to use the combination 9-8-2 to open the rusted doors successfully.

Understanding how to locate these codes efficiently saves valuable time during high-stakes nighttime scavenge runs. Players are encouraged to always utilize their survivor instinct ability when entering dark zones to quickly highlight nearby collectible notes and hidden lockboxes. Keeping a watchful eye on your surroundings ensures that no physical upgrade opportunity is left behind in the ruins of the city.
