ARC Raiders Stable Housing Guide: How to Get the Project Heartwood Blueprints

The Shrouded Sky update brought more depth to ARC Raiders, and the Stable Housing mission stands out as one of its more demanding mid-game objectives. Assigned by Tian Wen, this task sends you into the hostile depths of Stella Montis, where you must locate and extract the valuable Project Heartwood Blueprints—all in a single deployment.

Unlike standard objectives, this mission follows extraction rules. That means success isn't just about finding the item—it's about getting out alive with it.

Mission Breakdown

You'll need to complete every objective in one run:

1.Reach the Security Bridge

2.Locate the safe near the third-floor stairwell

3.Move up to the fourth-floor control room

4.Attempt to use the Access Card Printer

5.Find another way to unlock the safe

6.Collect the item inside

7.Extract and return the blueprints to Tian Wen

Each step builds on the last, so efficiency and awareness are key.

Step 1: Enter the Security Bridge

The Security Bridge is a multi-level structure inside Stella Montis, clearly marked on your map. It's a high-risk zone, often drawing both enemies and other players due to its valuable loot.From casual runs to high-stakes battles, MMOexp has the ARC Raiders Items you need to thrive.

Before heading in, prepare carefully:

Bring strong healing supplies to sustain extended fights

Pack breaching tools for locked rooms

Use weapons suited for tight interiors and vertical combat

Clear each level before pushing upward

Gaining control of staircases early is critical. If enemies control them later, escaping with the objective becomes much harder.

Step 2: Locate the Safe (Third Floor)

After entering the building:

Head up to the third floor (look for the "3" marking)

Move into the side room beside the stairwell

Check the back-right corner

Here you'll find the mission safe. It can be interacted with, but it won't open yet—this is part of the objective flow.

Step 3: Investigate the Control Room

Next, go up one more level:

Reach the fourth floor

Enter the room positioned directly above the safe

Locate the Access Card Printer

This device is supposed to generate the key needed to unlock the safe. However, it fails when used, forcing you to find another solution.

Step 4: Discover the Safe Code

Return to the third-floor room.

Once inside:

Turn right immediately

Look at the notice board on the wall

You'll find a code written there. Interacting with it automatically records the combination.

Go back to the safe, input the code, and it will unlock without requiring any additional tools or items.

Step 5: Secure the Blueprints

Inside the safe are the Project Heartwood Blueprints, the core objective of the mission.

At this stage, your focus should shift from looting to survival:

If you have a secure inventory slot, store the blueprints immediately

If not, you must extract successfully or risk losing them

This is where your preparation pays off. Mobility gear, defensive tools, and escape options can make the difference between success and failure.

Extraction Tips

Once you have the blueprints:

Avoid unnecessary engagements—survival is the priority

Use alternative routes instead of backtracking through danger zones

Stay aware of sound cues and nearby movement

Time your extraction to avoid crowded exits

Remember, the mission only counts as complete once you successfully extract.

Why This Mission Matters

Stable Housing is more than just a one-off objective. Completing it:

Progresses Tian Wen's storyline
