This guide shows how to open the locked door with Blackout Ring behind it in The Dark Conduit Dungeon of the game Remnant 2.
How to Open the Locked Red Door in Remnant 2 Dark Conduit
In order to unlock the door, you must navigate through the vent and disable the electric barrier that separates the cut wire. I have marked the location of the hidden vent in the map below.
Proceed to the right side of the locked door and continue until you reach a small room containing circular and cylindrical barrels, as depicted in the image below.
You can destroy these crates and boxes to uncover an underground vent and way inside the shaft.
Enter the vent and crawl through it. Then, find your way out through the first opening above you.
Ascend by using the ladder in front of you. Afterwards, proceed to the passage on the left side.
Upon reaching the end of the path, glance through the nearby opening along the wall and floor. Proceed to destroy the white barrel located between the cut wires. By doing this, you will unlock the door in the Dark Conduit area of Remnant 2.
You can now jump from the vent at the end of the passage to reach the locked door. This locked door will be open this time. Head inside to find the Blackout Ring.
