Horizon Zero Dawn Deep Secrets of the Earth Puzzle Guide

The Horizon Zero Dawn Deep Secrets of the Earth puzzle involves a bit of back tracking as initially Aloy is missing some components to fully solve the puzzle and restore power to the door.

When players enter the room, they will see both the panels on either side of Aloy. The panel on the left can be solved right away but the one on the right side is missing a ring.

To align the panel on the left, players can use their Focus Device (R3) on the wall panel to the left to see the correct combination. The direction of the red lines will indicate the alignment of the ring. The rings need to be aligned in the following sequence from left to right:

LEFT –> UP –> LEFT –> DOWN –> RIGHT

Once the puzzle on the right is done, the bunker door will open and players can proceed upstairs to get an emitter. Once they have the emitter, they need to go back downstairs and install it in the panel on the right side.

After the panel is in place, players can use their Focus Device to check the solution of the panel, however this is where another caveat kicks in as the rings have been turned around so their actual alignment is reversed. The ones facing up should be facing down and vice versa. The following is the correct combination to align this panel:

DOWN –> LEFT –> UP –> RIGHT –> DOWN

Once both panels are aligned, the Horizon Zero Dawn Deep Secrets of the Earth puzzle will be completed.
