There are multiple treasures to be found in Horizon Forbidden West. The Relic Ruins are collectibles that you find in old buildings. To get them, you have to solve a puzzle to reach the room where your prize is located. The No Man’s Land Relic Ruin is quite a challenge, due to its hidden path.
No Man’s Land Relic Ruin Solution
The No Man’s Land Relic Ruin is located Southeast of Plainsong. You can’t solve its puzzle before completing the “Death’s Door” main questline. Once you make it to the end, you’ll need to enter the code 2204.
This is a very complex puzzle compared to The Daunt. First, you must go to the left side of the building and pull a crate with the Pullcaster. You must use it to reach the upper part of the building, where you find a wall with firegleam. To destroy the red crystal, you must have the Igniter. Go through the new path to reach the middle room of the building.
In the new room, there are two panels. You will also find a Vip Key Message Log in the lower part that mentions a keycode (2204). Now, your challenge in this part is to energize the panel. The first thing you must do is open the wall in this room with the Pullcaster and turn right. Again, you need to use the Igniter to open the wall with firegleam. Get the energy cell that was behind the wall and carry it back to the room with the panels. Since it’s out of energy, you need to place it in the charged panel (right side from where you just came).
Your next challenge is to carry the energy cell to the other side without touching the water. To do that, jump to the second floor of this room. Now, you can see that there is a crate on the other side, but jumping won’t be enough to get there. So, use the glide to traverse.
Secondly, pull the crate and throw it down in the water. By positioning it right beside an elevated part next to where the cell was charging, you get on top of it with the energy cell. As a result, you can drop it there and pull the crate to the other side.
Once you put the energy cell in the other panel, you just need to climb to the upper part. Similar to the other ruins, there is a door with a panel beside it, which will ask you for the code. Inside you will find the ornament Emergency Pit Stop and will have completed the No Man’s Land Relic Ruin.
