How to open the Stagnant Manufactory Door in Remnant 2

Stagnant Manufactory is one of several potential side areas you can visit in Remnant 2’s The Dark Horizon DLC, and in it, you may encounter a locked door with no obvious way of opening it.

If you’re struggling to open this special door, then you’re in luck because I got the information you need to do just that.

How to open the door in Stagnant Manufactory – Remnant 2: The Dark Horizon

When you first approach the large steel door in Stagnant Manufactory, it is likely you will also encounter four patrolling mechs just outside of it. As with most enemies in Remnant 2, destroying them is a completely viable option to remove them from your sight, but doing so is problematic to opening this specific door.

When you first find this door, it is already open (or should be if you press the control button above the room), but you need to have noticed this to realize what is actually happening. The open door is your reward for solving the not-so-obvious puzzle just outside of it, which is reaching the door without being spotted by the mechs.

By engaging the mechs or even being spotted by them, the door will hasten shut, and you’ll need to reload the area to attempt it again. Stealth is the name of the game here, and unless you decide to embrace the playstyle, you won’t be reaching the door while it’s open. Thankfully, I’ve got a few tips to help you out.

Use Hunter’s Focus

The area surrounding the door is engulfed in a thick fog, making spotting the patrolling mechs quite difficult. Hunter’s Focus is an extremely helpful ability that will allow you to see the mechs through walls and the fog while the ability remains active. If you can, reallocate your points toward Skill Duration so that it remains active for longer. While active, plan your routes carefully by watching the routes the mechs take. There are four total, and none of them will deviate from their patrol designations.

Avoid the Hidey Hole

There is a hole you can hide in once you get into the room that may seem like a great place to gather your barrings while scoping out where the mechs are. However, I recommend avoiding taking refuge there because while it does offer you solace, it will not be all that useful for getting past the overlapping routes the mechs take. You’ll find yourself ‘stuck’ waiting for the briefest of moments to make a move, only to be discovered in the final hour.

Watch out for Red Lights

With the low visibility in the room, it will be difficult to see the mechs patrolling there while Hunter’s Focus is inactive. This is why I recommend you stop looking for the mechs in this scenario and look for their red searchlights instead. These red lights beam bright through the obscuring fog, and will immediately alert you when a mech is close while informing you of which way they are looking.

Have an Ally provide Overwatch

The control center for the door is right above it, just before you enter the elevator to go down into the room. There is a large window there that another player can look through and use to provide helpful intel on where the mechs are moving. Playing with a friend makes solving this stealth puzzle much easier for this reason. Be aware, however, that there are blind spots that the overwatching player cannot see from the control center.

What do you get for opening the Stagnant Manufactory Door in Remnant 2?

Should you manage to bypass the mechs and reach the door without being spotted, you’ll be rewarded with the Bypass Primer, a brand-new ring introduced in The Dark Horizon DLC.

It allows you to automatically reload your weapon when you successfully activate a Perfect Dodge, perfect for gun-focused builds that are always in the midst of the action. If you’re not yet aware, a Perfect Dodge is a dodge that successfully avoids an attack rather than just repositioning you. Rolling ‘through’ an attack with a dodge’s iframes (invulnerability frames) is considered a Perfect Dodge and will activate the reload effect of this ring.
