Horizon Zero Dawn Remastered: The Grave-Hoard Walkthrough

Finding Maker's End proved productive for Aloy in the previous main quest Horizon Zero Dawn Remastered. She learned the identity of the mysterious woman and discovered the term Project: Zero Dawn. She also found another potential clue to learn more about this mysterious project, and more answers can be found in the Tomb. Here's what to expect when you start The Grave-Hoard.

This guide contains spoilers, proceed with caution.

Go to the Grave-Hoard

After completing Maker's End, your next step is to head to the Grave Hoard. The Grave Hoard is far north of the Mother's Crown around the area where The Frozen Wilds DLC is happening. As you approach the destination, you will come across the Shell-Walker page. You can either ignore them or take them for their supplies. There is also a Watcher patrolling nearby, so keep an eye out for him.

As you approach the entrance to the Grave Hoard, you'll see a group of Eclipse guarding the path. 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. Right at the entrance will be a couple of guards and a Corrupt Guardian. After dealing with them, go down the zipline that will take you deeper into the ruins.

How to restore power to the bunker door

You'll have plenty of data points to collect from corpses as you go. Continue through narrow corridors and ruined rooms. Next you will find another zipline that goes down. At the bottom, you'll come across a bunker door that has no power.

To fix this, turn left and go further into the cave. This leads to an open chamber with four terminals directly in front of you and eight located on the floor below you. These terminals are referred to as hololocks and all must be rotated to certain positions to restore power.

Focusing on the locks at the bottom of the chamber, the first set is easy as the terminal on the left shows you the position where the holo locks need to be. For the first set, there should be a red spot on each lock in the following order: Up, Up, Down, Down. When entered correctly, the locks will light up light blue and the red will disappear.

The second set of locks on the bottom floor is more complicated. Unlike the first set, you won't get a combination on the machine next to it. Next to the machine is a data point with a sound file. Listen to this file and get the following hint:

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

In the case of a puzzle, the bird refers to the red part of the lock and the position in which it must be. Ignore the season as this part is not important to solving the puzzle. The solution to this puzzle from left to right is as follows: Up, Right, Left, Down. You can see the solution in the image above.

The terminal above also provides a solution for four holo locks, which is up, down, left and right. If you have activated all three sets, the door will be powered again.

Continue exploring the tomb

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

Unlike outside, there are fewer places to hide. Still, try to take out as many as you can with stealth so that you have an easier time in the fight if you are eventually detected. One of the cultists is armed with a Deathbringer Gun, so watch out for them.

When all the enemies are dead, go across the narrow walkway and jump to the other side. After that, look to the left and you'll see a section of rock wall ahead of you that you can jump onto and grab onto. Move to the right to reach a place where you can go up to the beam of light.

In this next area, you can either go left or straight into the room ahead. The room has some data points that you can collect while the corridor takes you closer to your destination. In the next room you will see a holoprojector that you can activate. After a short dialogue, enter the next chamber through the door on the right.

Destroy the Deathbringer

Just like in Maker's End, you'll encounter another Deathbringer. However, this one can move. He is also accompanied by five Eclipse Cultists. Go around the platform and drop down. Be careful which way the Deathbringer is facing, because even if you manage to stealth kill the cultist where you rappel down, the Deathbringer will notice you very quickly.

Take out the Cultists and then set the Deathbringer on fire with Fire Arrows. Make sure to keep moving and stay in cover as the Deathbringer will constantly unleash a barrage of attacks on you.

Search the war room

With the Deathbringer destroyed, go through the door under the stairs. Go through the hall and get to the War Room where there is another holo projector. Activate it and watch the holo video.

When the video is done, the door opens to reveal a ladder going up. Use this ladder to get back outside and complete this quest.
