How U4GM Solves the Arc Raiders Safe Puzzle

Submitted by iiak32 on Mon, 09/14/2026 - 21:21

Stable Housing in Arc Raiders is built around a misleading first step: the safe looks like the main problem, but the real answer comes from reading the rooms around it. Bring only what helps you reach Stella Montis and leave safely, since your objective is a quest item rather than a full loot run. Keeping your loadout focused also leaves room for useful ARC Raiders Items you may find along the way.

What makes Stable Housing easy to misread?

The quest sends you toward the Security Bridge, then points you to an Access Card printer on the floor above the safe. That sounds like the printer should produce the direct solution. It doesn't, and the failed interaction can make the mission feel stuck.

That moment is actually the quest's hint. You aren't meant to find a second entrance or wait for another printer prompt. The information you need is back in the room where the safe is located.

Which landmarks lead to the locked room?

Once you enter Stella Montis, work toward the upper section of the Security Bridge and find the stairwell connecting the floors. The safe is on the third floor, inside a side room near the stairs rather than in the main corridor.

Look for the large number 3 on the wall. It's the most useful visual marker in this part of the building, and it should lead you to the room containing the small safe and the android head.

Take a moment to remember the room before going higher. On a first attempt, it's easy to inspect the safe, head upstairs, and then lose time trying to retrace your steps after the printer interaction.

Why should you use the printer before checking the clue?

From the third-floor room, continue to the fourth-floor control room and interact with the Access Card printer. This advances Stable Housing, even though it doesn't hand you a working access card or open the safe.

Once the printer fails to solve the problem, return downstairs. The game expects you to connect that failed attempt with the nearby environmental clue, so searching the control room for a hidden switch will only delay the next step.

What code opens the safe in Stella Montis?

Back in the third-floor safe room, inspect the board beside the door. It contains the information needed for the lock, including the four-digit code for this quest.

Enter 2746 at the safe. You don't need another key, a special item, or a different path into the room. The board is the answer, and the printer interaction is what makes returning to it make sense.

What do you need to do after opening the safe?

The safe contains the Project Heartwood Blueprints. Pick them up and check that the quest objective updates before moving on. Opening the container alone isn't enough; the blueprints must survive the return trip out of Stella Montis.

Leave the building without turning the extraction into a second objective. ARC machines and other Raiders can still make the route dangerous, especially if you pause in exposed corridors or stairwells to sort your inventory.

If your inventory offers a protected quest-item slot, use it for the blueprints. That won't make the building safer, but it helps preserve the progress you've earned if the trip out goes badly.

What is the cleanest order for Stable Housing?

Start the quest with Tian Wen, enter Stella Montis, and reach the Security Bridge. Find the third-floor side room marked by the large 3, inspect the safe, then go to the fourth-floor control room and use the printer.

Return to the same safe room, read the board beside the door, enter 2746, and collect the Project Heartwood Blueprints. From there, head for extraction and deliver them to Tian Wen rather than making extra stops for optional loot.

Stable Housing becomes much simpler once you treat the printer as a clue instead of the solution. Afterward, plan your exit before picking up the blueprints, and keep your kit practical; ARC Raiders Coins for sale may help with preparation, but the quest itself is solved by the board beside the safe room door.
