Horizon Zero Dawn Bunker Code And How To Open The Door

Exploring ancient ruins in Horizon Zero Dawn often leads players to locked bunker doors that require power cells and holographic dial combinations to open. Resolving these puzzle mechanics is necessary to access hidden lore items and the powerful Shield-Weaver armor. Understanding how to locate missing components and input the correct dial sequences ensures a smooth journey through the game's post-apocalyptic world.

Finding the Required Power Cells

Before you can interact with the door controls in the Ancient Armory bunker, you must restore power to the system. Five power cells are hidden across main storyline locations, including the underground ruins from Aloy's childhood and Maker's End. Collecting these cells allows you to activate the holographic dials needed to breach the facility.

If you miss a power cell during a story mission, you can return to most locations later in the campaign. Searching each area thoroughly with Aloy's Focus makes tracking down these small items significantly easier.

Solving the Holographic Dial Puzzles

Once power is restored to the bunker door, you must align the holographic dials in specific directions. The code for the initial door lock can be found on nearby datapoint displays that show code angles. From left to right, turning the dials Up, Right, Down, Left, and Up restores function to the primary entryway.

Inside the facility, a second set of dials locks the final chamber. The required sequence for this inner mechanism from left to right is Right, East, Right, North, and South, which translates to Right, Left, Up, Right, and Left depending on the interface view.

Unlocking the Shield-Weaver Armor

Disengaging both lock sets opens the central vault holding the ancient technology. Players can claim the suit box directly from the platform and equip it from their inventory menu. This unique outfit projects an protective energy barrier that absorbs incoming damage from enemy attacks.

Equipping this gear substantially improves survivability during late-game machine encounters and boss fights. Completing this puzzle stands as one of the most rewarding side activities in Aloy's adventure.
