Found in Demeter’s region, Horizon Forbidden West Long Coast Relic Ruins require you to solve a puzzle far more complicated than all other Relic Ruins we have covered so far.
The Horizon 2 Forbidden West Long Coast Relic Ruins are nevertheless mandatory in the video game published by Sony Interactive Entertainment because they hide an Ornament you’ll need to retrieve.
However, getting the Long Coast Relic Ruins Ornament is not as easy as it seems because there are specific steps you’ll have to follow to reach it.
Assuming you don’t know what to do, throughout the guide below, I’ll tell you where to find the Long Coast Relic Ruins Ornament in Horizon Forbidden West and how to get to it.
Horizon Forbidden West Long Coast Ruins Location – Where To Find
Again, let’s start with the location of the Long Coast Ruins in Horizon Forbidden West.
As you can see on my may, these are found on the western side of Demeter’s Regions, northeast of Thornmarsh Settlement.
Furthermore, on the map above, you can also notice the starting point or the location you should consider approaching if you want to enter the ruins.
The said location is, as you can observe, northeast.
Long Coast Relic Ruins Walkthrough – How To Gather The Ornament
To get the Ornament inside The Long Coast Ruins, you’ll need two essential items:
- The Igniter
- An Energy Cell
While the second item is within the ruins, the Igniter, which allows you to remove Firegleams, is a Special Tool you can get by progressing through the story (as outlined in this guide).
So assuming you already have the Igniter, head inside and start looking around.
Your first objective is to find a lever Aloy can pull to move a small platform.
While facing the lever and the broken wall nearby, turn right and look for a ledge you can climb.
It’s right around the corner, near the lever.
Upon reaching the rusted platform, cross it, then use the climbing points on the other side.
Head right and drop in the room with the Firegleam.
Use the Igniter to blow up the wall behind the Firegleam, then exit through the hole you just created.
Now, turn around, and you’ll spot the lever through a small hole in the wall on the other side.
The trick here is to use the Pullcaster on the lever pictured below.
By pulling the lever, you’ll activate a moving Grappling Point.
It should be on your left side as you look up. Once you pull the lever, double-tap X to quickly jump on the moving grappling point (below).
Now, quickly press O to perform a back jump on the platform pictured above.
Here you’ll want to pull the crate so it can fall to the ground through the hole in the rusted platform.
Next, it’s time to move the crate west. Grab it, move it towards the lower area, and drop it below. Now the crate should float in the water.
Jump after it, and while on the ground, pull it towards you.
Your next objective is to grab the crate and bring it to the elevator shaft in the next section of the ruins.
After you place the crate inside the elevator, it’s time to power it up, but for this, you need a Power Cell.
Long Coast Relic Ruins Power Cell Location – How To Get
To get the Power Cell or the Battery that activates the elevator, after you move the first crate inside the shaft, turn around, and you’ll see some stairs.
Head up, then turn left, and on the upper floor, you should spot the Power Cell Terminal.
Get the Battery inside, then quickly return to the elevator shaft and place it inside the station on the exterior wall to power up the elevator.
Awesome job! Now, with the first crate inside the elevator, which is now active, head inside and take it to the second floor.
The Long Coast Ruins Crates Puzzle – How To Solve
Turn right and go around the large tower when you exit the elevator. This is the trickiest part of the ruins, so follow the exact steps below.
You’ll see several ledges and climbing points when you go around the tower.
Use them to ascend to the upper floor, then go around the central structure, and while facing the courtyard, look for another crate behind a wall (pictured below).
What you have to do next is glide to that crate, then destroy the Firegleam nearby to clear the path.
Grab the crate, push it up the ramp, and drop it on the ground floor.
Now, call the elevator and push the second crate inside.
The next step is to get inside the elevator with the two crates and remove the panel on the ceiling.
Excellent, now, take the elevator to the upper floor, and grab one of the crates.
Pull it out, then take the elevator to the ground floor.
Finally, exit through the hole in the ceiling and return to the second floor. Here you’ll want to push the crate on the second floor inside the elevator shaft.
At this point, you should have one crate inside the elevator and one on top of it.
This means that you can head back to the ground floor and get inside the elevator. Take it to the second floor, then head through the hole in the ceiling.
Now jump on the second crate (on top of the elevator), then on the yellow ladder, which takes you to the room where the Long Coast Relic Ruins Ornament awaits.
Long Coast Ornament – How To Use
You can use the Long Coast Relic Ruins Ornament you just found when you reach Hidden Ember, where you’ll meet Stemmur.
Stemmur will trade all 9 Ornaments for nine animations that allow you to change the night sky in the desert.
On top of this, you’ll be able to unlock Stemmur’s stash and get the Ancestor’s Return Legendary Shredder Gauntlet; but you’ll have to finish all 9 Relic Ruins in the game for this weapon.
