Unlocking the Shield-Weaver outfit in Horizon Zero Dawn is one of the most rewarding pursuits for players exploring Aloy's post-apocalyptic world. This legendary armor provides an rechargeable force field that absorbs massive damage before Aloy takes health loss. To gain access to the bunker containing this technology, players must retrieve five hidden Power Cells scattered across primary story mission locations.

Early Game Power Cell Locations

The first Power Cell can be found early during Aloy's childhood exploration in the underground Vault. Returning to this location as an adult allows players to smash through stalactites blocking access to the room containing the item. Collecting this initial cell sets the foundation for tracking down the remaining components later in the journey.

Another early-game location is Mother's Watch, accessible during or after the quest titled The Proving. If missed during the main story, players can return to the village later when the gates open during main story progression. Searching carefully behind locked doors inside the mountain facility will reveal the second Power Cell.

Mid-Game Story Ruins Exploration

As Aloy ventures beyond the Sacred Lands, the third Power Cell becomes accessible during the Maker's End quest. Ascending to the very top of the Faro Automated Solutions skyscraper requires climbing past the main objective level. Reaching the highest point of the exterior ruins rewards players with the cell tucked away on a ledge.

The fourth item is hidden within the Grave-Hoard facility during a critical story arc. Navigating through the ancient subterranean military base leads Aloy to a series of ring puzzles. Solving these door locks allows entry into a side chamber where the Power Cell sits waiting to be collected.

Final Power Cell and Unlocking the Shield-Weaver Armor

The final Power Cell resides in GAIA Prime, visited near the climax of the main campaign during the quest titled The Mountain That Fell. Before rappelling down the main drop point, players should carefully explore the cliffs to find a hidden side tunnel. This path leads directly to the fifth cell required to complete the collection.

Once all five items are gathered, returning to the Ancient Armory bunker in the Sacred Lands allows Aloy to solve two terminal puzzle sets. Restoring power to the mechanism opens the containment chamber and grants access to the powerful Shield-Weaver outfit. Equipping this armor significantly changes combat dynamics, making high-level machine encounters much more manageable.
