This chapter contains a complete walkthrough for the mission The Ancient Armory. Here you will find advice that will help you in completing this quest in best way possible.
Beginning the quest
The mission will appear in your journal when you pick up one of the five power cells scattered across the world. It might also appear when you get close to the armor in a bunker related to the mission.
Your task is go get to the room with the very strong armor. To do it, you must open the door to the chamber with the armor and then deactivate the force field that surrounds it. Then you will be able to interact with the armor and pick it up.
First you must find the power cells that enable you to interact with the power control panel.
In this section you will find advice related to the location of the cells in five places related to the mission.
The cell is in one of the side corridors inside the mountain. You will find an entrance to a ventilation shaft near the place where Aloy found a Focus in the mission The Womb of the Mountain. Use it to reach the power cell. After The Womb of the Mountain missions ends, the access to the location will be locked until The Heart of Nora mission. After it you will have a free access to the location.
Ruins from the prologue
Once Aloy grows up, go back to the prologue. Thanks to the spear you can get rid of the stalactites and stalagmites that block access to the cave with the cell. The point is located near the place where you started the adventure.
On the highest level of the location, in the place where you can see holograms, you will find a high pillar. Climb on the top and you will find a power cell.
After solving the riddle in the ruins during the Grave-Hoard mission, go towards the door that you powered up and open it. Behind it, on the third floor you will find another power cell in a small stash.
The cell can be found in one of the chambers during the mission The Mountain that Fell. After entering the facility, Aloy will ride down to the lower floor. There you must go left and climb on a small ledge. You will gain access to the location.
Solve the riddle
Once you have all power sells, you can go back to the Bunker with the armor. First you must place two cells in the console. This will enable you to interact with it.
Once the panel is prepared, interact with the ciphering machine. You will see the above picture. The information represents the position of the cells as clock hours, it shouldn't be very hard.
From left: up, right, down, left, up.
Once you set the power cells in correct position, the door to the main chamber with the armor will open. You can't walk there yet, first you must deactivate the force field. Go to the opposite side of the ruins. The door from the armor room leads there directly.
There you will find another panel. You must put three power cells in it. This time the power cells must be placed based on the level of lean from the base position.
From left: right, left, up, right, left.
Take the armor
After powering up both sections, all that is left is to take the armor from the table. It will land in the equipment in a special chest from which you can pull it out. Then it will become an item ready to equip.
