Since this must all be done in ARC Raiders Coins one deployment, preparation is key. Bring solid mid-range weapons for tight interiors, ensure you have healing supplies, and clear rooms carefully - Stella Montis is rarely empty.

Step 1: Reach the Security Bridge

Your first destination is the Security Bridge, clearly marked on your in-game map. Stella Montis veterans will recognize it immediately: a four-story tower-like structure where most rooms require breaching before entry.

Expect resistance both inside and around the building. Raiders and ARC threats may already be fighting each other, so approach cautiously and listen for audio cues before pushing upward.

Once inside, begin ascending the structure.

Step 2: Locate the Safe on the Third Floor

Head up to the third floor. You'll know you're in the right place thanks to the large painted number "3" near the staircase landing.

Instead of entering the main open area, move into the side room located behind the stair banisters. This smaller room is easy to miss if you rush through the level.

Inside, check the back-right corner. That's where you'll find the safe required for the quest. Interact with it to progress the objective, but don't expect to open it just yet - you'll need a key.

Step 3: Visit the Fourth-Floor Control Room

With the safe located, your next task is directly above you.

Climb to the fourth floor and enter the corresponding room above the one you just searched. This is the control room, and inside you'll find the Access Card Printer - the device meant to generate the key for the safe.

Interact with the printer to attempt to create the access card.

Step 4: The Printer Fails - Time to Improvise

Here's where the mission throws a curveball.

When you try to use the Access Card Printer, it breaks. No key, no clean solution, and no shortcut. This forces you to complete the next objective: find an alternate way into the safe.

Instead of wandering aimlessly, return to the third-floor side room where the safe is located.

Step 5: Discover the Alternate Entry Method

Once back inside the third-floor room, stop just after entering and look immediately to your right.

You'll see a notice board mounted on the wall. Interact with it to inspect its contents. Among the papers posted there is an alphanumeric code - conveniently left behind for reasons only the inhabitants of Stella Montis could justify.

After interacting with the board, your character automatically memorizes the code.

Turn back toward the safe and interact with it again. This time, you'll be able to input the code and unlock it successfully.

Step 6: Retrieve the Project Heartwood Blueprints

Inside the safe, you'll find the Project Heartwood Blueprints, the critical quest item Tian Wen sent you to retrieve.

Now the tension spikes. Unlike earlier steps confined to one building, you must now survive long enough to deliver the blueprints.

If you have a safe pocket, place the blueprints inside immediately. This ensures they remain secure even if you're eliminated before extraction. If you don't have one available, your top priority becomes reaching an extraction point safely.

Avoid unnecessary engagements. The Security Bridge can attract attention due to frequent player traffic, so rotate carefully and listen for footsteps.

Step 7: Extract and Deliver to Tian Wen

Your final objective is simple in theory: extract and deliver the blueprints to Tian Wen.

Choose the safest extraction zone available rather than the closest one if necessary. A slightly longer route is better than losing progress and restarting the entire quest chain.

Once extracted successfully, turn in the Project Heartwood Blueprints to Tian Wen to complete the "Stable Housing" mission.

Tips for Completing ‘Stable Housing' Safely

Clear floors methodically. The vertical structure makes it easy to get flanked.

Watch stairwells. They're natural choke points and prime ambush locations.

Bring breach tools. Security Bridge rooms often require forced entry.

Use audio. Footsteps above or below you can reveal enemy positions.

Secure the blueprints immediately. Safe pockets dramatically reduce stress during extraction.

Final Thoughts

"Stable Housing" is a compact but cleverly designed quest that reinforces Arc Raiders' risk-versus-reward gameplay. The broken printer twist forces players to slow down and explore rather than relying on straightforward objectives. It's a great example of environmental storytelling mixed with practical puzzle-solving.

With careful movement, smart looting, and a safe extraction plan, you can secure the Project Heartwood Blueprints in buy ARC Raiders Coins a single run and complete the mission without unnecessary setbacks.
