The Mountain That Fell Power Cell Location And Puzzle Guide
Unlocking the ultimate defensive armor in Horizon Zero Dawn requires players to track down several rare items scattered across the post-apocalyptic landscape. During the late-game main quest titled The Mountain That Fell, adventurers gain access to a highly fortified facility containing one of the most vital components. Finding this specific item is essential for complete progression and unlocking the powerful Shield-Weaver outfit.
Reaching the Secret Facility Ruins
Navigating to the designated area requires players to ascend the bitter cold trails of GAIA Prime. The path is filled with high-level machines that demand careful combat preparation or stealth strategies. Once you reach the interior ruins of the mountain structure, you must stay alert for hidden pathways that deviate from the primary quest objectives.
After entering the main complex and experiencing the initial holographic story cutscenes, you will eventually reach a point where you must rappel down into an open area. Instead of immediately following the main quest marker forward, turn around to explore the edges of the metallic structure. A carefully hidden ledge allows you to climb downward into a secret room where the glowing power cell rests on a shelf.
Solving the Ancient Armory Dial Puzzle
Acquiring the power cell from the frozen peaks is only half of the challenge required to claim your ultimate reward. Players must return to the Ancient Armory bunker location to insert the missing component into the mechanical wall mechanism. Doing so activates an environmental security check that involves interacting with a row of five electronic holographic dials.
The solution to this mechanism relies heavily on interpreting nearby terminal clues, which display codes based on military time or basic mathematical degrees. For this specific section, you need to turn the circular dials to match the correct positions indicated by the environmental monitors. Rotating the interfaces to point right, left, up, right, and left will restore full power to the main chamber door.
Claiming the Shield-Weaver Prize
Bypassing the mechanical locks grants you immediate access to the sealed chamber containing the experimental technological prototype. Interacting with the armor container allows you to retrieve a specialized treasure box from your inventory menu. Opening this box officially equips Aloy with an advanced forcefield capability that completely alters your tactical approach to high-level machine combat encounters.
This unique outfit absorbs an incredible amount of incoming physical and elemental damage before requiring a brief period to recharge. Utilizing this gear significantly enhances your survivability during the grueling final story missions and new game plus challenges. Understanding these secret locations ensures that your tribal hunter is perfectly prepared for the threats waiting in the dangerous wild world.
