Horizon Zero Dawn Remastered: The Grave-Hoard Walkthrough

The search for Maker's End proved fruitful for Aloy in the previous main quest Horizon Zero Dawn Remastered. She learns the identity of the mysterious woman and discovers the word Project: Zero Dawn. He also finds another possible lead to learn more about this mysterious project, and more answers can be found in the grave-hoard. Here's what you can expect when you start Grave-Hoard.

This walkthrough contains spoilers, proceed with caution.

Go to the grave-hoard

After you've completed the Maker's End, your next step will be to head to the Grave Horde. The grave hoard surrounds the area far north of Mother's Crown Frozen Wilds DLC takes place. As you approach your destination, you will encounter a Shell-Walker site. You can either ignore them, or take them out for their supplies. There is also a guard patrol nearby, so keep an eye out for it.

As you approach the entrance to the Grave Horde, you'll see a group of eclipses guarding the passage. Take them out and continue down the path towards the remains of the large machine. The entrance is in a hole in the ground south of the campfire. There will be a pair of guards and a corrupt watcher immediately at the entrance. After you've dealt with them, jump on the zipline that takes you deep into the ruins.

How to restore power to the bunker door

There will be several datapoints to collect from the corpses as you go. Continue through narrow hallways and ruined rooms. Ahead, you'll find another zipline that goes down. Below, you'll find a bunker door that has no power.

To fix it, turn left and go forward into the cave. This leads to four terminals in front of you and eight open chambers located on the floor below you. These terminals are called hollow locks, and they all need to be rotated to certain positions to restore power.

Focusing on the locks at the bottom of the chamber, the first set is easy because the terminal on the left shows you the position where the hollow locks should be. For the first set, each lock should have a red spot. The following order: up, up, down, down. If entered correctly, the locks will disappear in light blue and red.

The second set of locks on the lower floor is trickier. Unlike the first set, you are not given a combination on the machine next to it. Next to the machine is a datapoint with an audio file. Listen to this file to get the following clues:

The bird flies north in summer, east in spring, west in autumn and south in winter.

In the case of the puzzle, the bird represents the red part of the lock and the position in which it should be placed. Ignore the seasons, as that part is not important to solving the puzzle. The left-to-right solution to this puzzle is as follows: Up, Right, Left, Down. You can see the solution in the image above.

The upper floor terminal also provides a solution for four hollow locks, which are up, down, left and right. If you activate all three sets, the door will have power again.

Continue exploring the grave-hoard

Return to the door and go through it. Behind this door is another one of the power cells needed to get the Shield Weaver Armor. There will also be a group of eight Eclipse Cultists and one Corrupt Watcher.

Unlike the outdoors, there are fewer places to hide. However, try to sneak out as many as possible so you'll have an easier time fighting if you're discovered. One of the cultists is armed with a Deathbringer Gun, so take care of them.

When all the enemies are dead, go down the narrow walkway and jump to the other side. After that, look to the left to find a section of rock wall ahead that you can jump and latch onto. Move to the right to get to where you can go towards the beam of light.

In this next area, you can go left or straight into the room in front of you. As the hallway takes you closer to your destination there are some datapoints in the room that you can collect. In the next room, you'll see a holo-projector that you can activate. After a short conversation, enter the next room through the door on your right.

Destroy the Deathbringer

Just like Maker's End, you meet another Deathbringer. However, it is able to move around. It is also accompanied by five eclipse cultists. Go around the platform and rappel down. Pay attention to which direction the Deathbringer is facing, as you'll quickly notice if you manage to kill the Cultist with a thief where you rappel the Deathbringer down.

Take out the cultists and then set the Deathbringer on fire with the Fire Arrow. Make sure to move and stay behind cover as the Deathbringer is constantly unleashing a barrage of attacks on you.

Find the war room

After the Deathbringer is destroyed, go through the door under the stairs. Go through the hall to the war room where there is another holo projector. Activate it and watch the holo video.

When the video ends, a door opens, revealing a staircase leading up. Using this ladder will take you back outside and complete this quest.
