Unlocking the legendary Shield-Weaver armor in Horizon Zero Dawn requires players to locate five hidden Power Cells scattered across the post-apocalyptic world. This powerful outfit projects a protective forcefield around Aloy, absorbing damage before her health bar takes a hit. Tracking down each cell involves revisiting main story ruins and keeping up with daily gaming news for useful tips on navigating late-game dungeons efficiently.

Early Game Power Cells in Ancient Ruins

The first Power Cell can be retrieved early in the game by returning to the underground ruin Aloy explored as a child. Force open the sealed doorway using her spear to access the previously locked room and grab the item from a table. The second cell is hidden inside All-Mother Mountain during or after the quest The Womb of the Mountain. Search the side tunnels near the locked bunker door before exiting the mountain facility.

High-Altitude Exploration at Maker's End and Grave-Hoard

As Aloy's quest takes her northward, the third Power Cell sits at the very summit of the Faro Automated Solutions skyscraper during the Maker's End mission. Climb past the main objective platform to the highest spire above Ted Faro's office to find it sitting on a ledge. The fourth cell is located deep within the frozen facilities of the Grave-Hoard. After solving the ring puzzle to restore power to the side door, pick up the cell resting right inside the doorway.

The Final Cell at GAIA Prime and Unlocking the Armor

The fifth and final Power Cell is located inside the GAIA Prime ruins during the main story quest The Mountain That Fell. Before descending down the zip-line, turn back and carefully drop down the rocky cliffside to access a hidden cave. Once all five cells are in your inventory, return to the Ancient Armory bunker near Mother's Rise. Insert the cells into the power dials, solve the two clock-based puzzle locks, and claim the Shield-Weaver outfit to make Aloy nearly invincible.
