ARC Raiders Stable Housing Mission Guide: How to Obtain Project Heartwood Blueprints

Mar-23-2026 PST

With the release of the Shrouded Sky update, ARC Raiders introduces a variety of deeper, more complex missions—and the Stable Housing quest stands out as a true mid-game challenge. Assigned by Tian Wen, this objective pushes players into the hazardous depths of Stella Montis, where they must locate and extract the valuable Project Heartwood Blueprints in a single run.


Unlike simpler missions, this one demands precision, planning, and awareness. Because everything must be completed in one raid, even a small mistake can cost you the entire objective.


To complete the Stable Housing quest, you'll need to finish all of the following steps in one attempt:


1.Reach the Security Bridge


2.Locate the safe on the third floor


3.Access the fourth-floor control room


4.Attempt to generate a key


5.Discover an alternate way to open the safe


6.Secure the blueprints


7.Extract and return them to Tian Wen


Let's walk through the most efficient way to handle each stage.


Step 1: Enter the Security Bridge


The Security Bridge is a multi-level structure within Stella Montis, easily identified on your map. This four-story building is notorious for tight interiors and frequent player encounters, making it a high-risk zone.


Before heading in, make sure you're properly equipped:


Bring healing-focused gear to sustain prolonged fights


Carry breaching tools for locked rooms


Use versatile weapons suited for mid-range engagements


Consider utility items like smokes or mobility tools


Clearing enemies floor by floor is highly recommended. Securing the staircases early gives you control over movement and prevents being trapped later—especially important once you're carrying the mission ARC Raiders Items.


Step 2: Locate the Safe (Third Floor)


After entering the building:


Make your way up to the third floor (watch for the "3" marking near the stairs)


Move into the side room adjacent to the stairwell


Check the back-right corner


Here, you'll find the quest-related safe. You can interact with it, but it won't open yet—this is part of the intended progression.


Step 3: Access the Fourth Floor


Next, head up one more level:


Go to the fourth floor


Enter the room directly above the safe's location


Find the Access Card Printer


This device is supposed to create a key for the safe. However, when you attempt to use it, it malfunctions—forcing you to find another solution.


This moment often confuses players and wastes valuable time, so knowing what comes next is crucial.


Step 4: Find the Alternate Code


Return to the third-floor room where the safe is located.


Once inside:


Turn right immediately


Look for a notice board mounted on the wall


Interact with it to reveal a code


Your character will automatically memorize the code after inspection.


Now, turn back to the safe, input the code, and unlock it—no keycard or hacking device required.


Step 5: Secure the Blueprints


Inside the safe, you'll finally find the Project Heartwood Blueprints, the key item for this mission.


From here, your objective shifts completely: survival becomes your top priority.


If you have a secure inventory slot, store the blueprints immediately to prevent losing them upon death. Otherwise, you'll need to successfully extract to keep them.


Using the right gear here can make all the difference. Smoke grenades, mobility tools, and defensive equipment can help you escape dangerous encounters and reach extraction safely.


Why This Quest Matters


The Stable Housing mission is more than just a one-off task—it plays a key role in your overall progression. Completing it will:


Advance Tian Wen's storyline


Unlock new crafting opportunities


Open access to higher-tier equipment paths
