One major catch: every step must be completed in a single round. If you extract early or fall in combat, you'll have to start over. Below is a complete step-by-step guide to finishing "Stable Housing," including how to ARC Raiders Coins locate the safe and unlock it when the obvious solution fails.

All ‘Stable Housing' Quest Steps

Before diving into specifics, here's a full breakdown of the seven required objectives:

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 to print a key to the safe.

Search for an alternate way into the safe.

Retrieve the contents of the safe.

Deliver the Project Heartwood Blueprints to Tian Wen.

Since this must all be done in 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 ARC Raiders BluePrints 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.
