Ancient Armory is a special side quest in Horizon Zero Dawn, which leads you to a special reward: the Shield-Weaver armor, which is also known as UltraWeave Mk7.1. This armor offers a special type of protection - a shield that takes all the hits for you. Honestly, it’s one of the best armors you can get in the game.
Getting your hands on this Shield-Weaver armor is a bit of a challenge. You need to find 5 Power Cells hidden around the game world. When you’ve gathered all the Power Cells, there’s a puzzle waiting for you in a final bunker with the armor. Solve it, and the armor is yours!
In this guide, I’ll walk you through the Ancient Armory quest in Horizon Zero Dawn. We’ll cover how to kick off the quest, where to find each Power Cell, how to solve those puzzles, and finally, how to claim the Shield-Weaver.
Start the Ancient Armory Quest
Starting the Horizon Zero Dawn Ancient Armory quest is pretty straightforward, and there are two ways to do it.
First, you can just head to the place where the armor is locked up. This is in a cave to the east of Mother’s Rise. When you get there and start going down into the cave, the quest will begin all by itself.
The second way to start the quest is by finding a Power Cell. These are special items you need to unlock the armor. There are 5 Power Cells hidden around the game world. As soon as you find your first one, the quest will start. You can get your first Power Cell in one of the early main missions, called The Womb of the Mountain.
Actually, I suggest you not to lose time and start collecting the Power Cells, and the quest will start automatically.
Find 5 Power Cells
Power Cells in Horizon Zero Dawn are the main part of the Ancient Armory quest. You need to find 5 of these Power Cells, which may take you some time, even with our guide.
There’s no direct map that shows where these Power Cells are, and the game doesn’t give you many clues. So, better to use our guide with all the Horizon Zero Dawn Power Cell locations.
These Power Cells are usually hidden in old ruins, way down underground in forgotten facilities and labs. This means you’ll need a bit of patience to get all of the Cells and finish the Ancient Armory quest.
To make it simple, here’s where you can find the Power Cells.
Power Cell 1
The first Power Cell is hidden in the Underground Bunker. This is the place where young Aloy finds her Focus.
Power Cell 2
The second Power Cell is in the All-Mother Temple. Grab this Power Cell during the main story quest “The Womb of the Mountain”.
