Finding every hidden power cell in Horizon Zero Dawn is one of the most fulfilling journeys completionists can undertake. These rare components are scattered across massive ruins that Aloy visits throughout her primary questline. By securing all five items, players can unlock the legendary Shield-Weaver armor inside an ancient, forgotten bunker.
The Initial Discoveries in Mother Embrace
Your search begins near the starting area where Aloy spent her early years learning to survive. The very first component rests inside the underground ruins that you fell into during the opening prologue sequence. You can return as an adult to smash the stalactites with your spear and claim the prize.
The next location presents itself inside the sacred All-Mother mountain during the Womb of the Mountain quest. Before leaving the facility, look carefully for a side room containing a small ventilation shaft you can crawl through. Navigating this tunnel reveals a hidden chamber where the second battery awaits discovery.
Scaling Ancient Structures and Ruined Vaults
As the story progresses, you will travel far north to investigate the remnants of the Old Ones. The third power cell sits at the peak of the tower located in Maker End. You must climb past the main office area using the yellow handholds to reach the absolute summit.
Following this mechanical trail leads straight into the frozen depths of the Grave-Hoard facility. While navigating the cold corridors, keep a close watch on the surrounding side rooms before heading toward the exit. The fourth component lies tucked away on a ledge near a group of old computer consoles.
The Final Piece and Unlocking the Shield-Weaver
The final battery is located inside the crumbling ruins of GAIA Prime, which opens up during the quest titled The Mountain That Fell. After sliding down the outdoor zipline near the end of the area, turn around completely to spot a hidden ledge. Climbing up this rock face reveals a small cave containing the last necessary component.
With all five pieces secured, you can navigate back to the bunker near Devil Thirst to solve the remaining ring puzzles. The holographic locks require you to turn the dials based on military time and geometric angles shown on the walls. Solving these mechanisms drops the final energy barrier and grants you access to the strongest outfit in the game.
