Arc Raiders Stable Housing Quest Guide – Full Stella Montis Walkthrough

If you have spent real time inside Stella Montis, you already know this place is not designed to be friendly. It is tight, vertical, full of angles, and almost always crawling with players hunting the same objectives you are.

This Arc Raiders Stable Housing quest guide breaks down everything you need to complete the mission in one round, including how to open the safe in Security Bridge, where to find the alternate access code, and how to extract with the Project Heartwood Blueprints without throwing your progress away.

Stable Housing was added in the Shrouded Sky update and sends you straight back into the chaos of Stella Montis on behalf of Tian Wen. On paper, it sounds simple. Open a safe and deliver the contents.

In practice, it is classic Arc Raiders tension.

Stable Housing Quest Objectives Overview

Before you load in, understand the full objective chain. The arc raiders stable housing quest must be completed in a single raid. If you die before extracting with the quest item, you start over.

Here are the required steps:

Go to the Security Bridge
Search for the safe in the side room by the third floor staircases
Head upstairs to the fourth floor control room
Use the Access Card Printer
Search for an alternate way into the safe
Retrieve the Project Heartwood Blueprints
Deliver the blueprints to Tian Wen

Every one of these steps happens inside Stella Montis. That means PvP pressure is constant.

Where to Find the Security Bridge in Stella Montis

Security Bridge is located in the northern section of Stella Montis, near the Lobby area. It is the tall four story tower that most experienced players recognize immediately. Each floor has tight corridors and breaching doors, which makes it a common hotspot for fights.

Veteran tip. Do not sprint straight in.

Clear the ground floor first. Players love to hold staircases in this building because vertical control equals free kills. Move slowly, listen for footsteps, and secure each level before pushing higher.

Where to Find the Safe on the Third Floor

Once inside Security Bridge, head up to the third floor. You will see a large number three painted near the staircase wall.

On the third floor, look for the side room located behind the stairwell banisters. Enter the room and check the back right corner. The safe is sitting on a desk.

Interact with it.

At this stage of the arc raiders stable housing quest, the game directs you upstairs to print an access card. It feels straightforward, but that is where things change.

Fourth Floor Control Room and the Broken Printer

Head up to the fourth floor. The control room is directly above the safe room, almost mirrored in layout.

Inside, you will find the Access Card Printer on the right side of the room. Interact with it to attempt printing a key.

It fails.

This is scripted. The printer is supposed to break. Do not waste time trying to force it to work.

This is where Stable Housing shifts from simple objective to environmental puzzle.

How to Find the Alternate Way Into the Safe

Now you return to the third floor safe room.

As soon as you enter, look to your immediate right near the doorway. There is a notice board tucked between the wall and a terminal. It is easy to miss if you rush.

Interact with the notice board.

Your character will inspect the notes and automatically learn an alphanumeric code written there. This is the alternate safe access method.

Turn back to the safe and interact again. This time, you can input the code and open it successfully.

Inside, you will find the Project Heartwood Blueprints.

Pick them up immediately.

Retrieving the Project Heartwood Blueprints Safely

The Project Heartwood Blueprints are the core objective item for the arc raiders stable housing quest. Without extracting with them, the quest does not complete.

If you have a safe pocket, place the blueprints inside right away. That guarantees progress even if you get eliminated.

If you do not have a safe pocket, your priority becomes survival.

Security Bridge sits close to an extraction point. The safest route is usually down to the bottom floor, out the main entrance, then toward the subway stairs north of the building.

Move carefully. Do not sprint into open sightlines. Stella Montis punishes careless movement.

PvP and ARC Survival Tips for Stable Housing

Over dozens of Stella Montis runs, a few patterns always repeat.

Clear Floors Methodically
Do not skip floors while climbing. Even one unchecked room can mean someone flanking you on the way back down.

Expect Other Quest Runners
Stable Housing is not a hidden quest. Other players are often doing the same objective. If you hear fighting above you, consider letting them finish and then move in.

Use Close to Mid Range Weapons
Security Bridge is tight. SMGs, shotguns, and balanced assault rifles perform best. Long range builds feel awkward in stairwells.

Manage ARC Threat
Extended gunfire can attract ARC patrols. Clear engagements quickly and reposition before reinforcements arrive.

Why Stable Housing Matters in Arc Raiders Progression

Stable Housing connects directly to Tian Wen and the broader Project Heartwood storyline introduced during Shrouded Sky. Completing it unlocks further quest progression and reinforces your familiarity with Stella Montis, which is one of the most important underground facilities in Arc Raiders.

Beyond story progression, the quest trains map discipline. You learn vertical control, extraction awareness, and risk management under pressure.

If you are already farming the area, you can combine this run with high value loot routes. Just do not get greedy while carrying quest items.

Preparing Your Loadout for Stella Montis

Preparation often determines success more than mechanical skill.

Bring reliable armor and healing. Do not over invest, but do not go in undergeared either. You need enough strength to win a sudden fight inside a staircase choke point.

Balanced mobility is valuable too. Quick repositioning can mean the difference between extracting with the blueprints or losing them at the last second.

Some players speed up their progression by trading for Arc Raiders items through community marketplaces like G4mmo, but no gear replaces good positioning and sound awareness.

Common Stable Housing Mistakes to Avoid

Ignoring the Notice Board
Many players waste time upstairs with the printer. The real solution is on the third floor.

Forgetting It Must Be Done in One Raid
You cannot split progress across runs. If you fail to extract, you repeat everything.

Looting After Opening the Safe
Once you have the Project Heartwood Blueprints, your job is extraction. Extra loot is not worth resetting the quest.

Final Thoughts

The arc raiders stable housing quest guide ultimately comes down to awareness, patience, and map control.

Mechanically, the steps are simple. Go to Security Bridge. Find the safe. Discover the alternate code on the notice board. Open the safe. Extract with the Project Heartwood Blueprints.

But Arc Raiders is never just about mechanics. It is about reading player movement, controlling vertical space, and knowing when to disengage.

Approach Stella Montis with respect. Clear deliberately. Extract smart.

Do that consistently, and Stable Housing stops feeling like a deathtrap and starts feeling like just another successful raid under your belt.
