ARC Raiders Project Heartwood Guide by U4GM

Blustery

Project Heartwood is one of those quest pickups that sounds simple until you reach Stella Montis and realise how exposed every hallway feels. Stable Housing sends you into Security Bridge to recover a set of documents for Tian Wen, not to clear the whole site or chase every container you see. If you are trying to build up a useful collection of ARC Raiders BluePrints, this job is worth doing early, since it moves your quest line along and gives you a reason to learn one of the map's most awkward indoor routes. Go in with a clear purpose. Grab the papers, get out, and leave the sightseeing for another run.

Get Ready Before You Drop In

Stella Montis punishes players who arrive overstuffed and underprepared. You do not need your favourite loadout for Stable Housing, but you do need something dependable enough to handle a close-range surprise. Bring healing, a weapon you know how to use, and enough room in your pack for the quest item. A mobility tool can save a run when the route gets crowded. It is also smart to keep some Coins aside before heading in. Replacement gear costs add up, especially when a few rough expeditions land back-to-back. Plenty of players make the same mistake: they enter carrying everything valuable, spot extra loot, then stay far longer than the mission calls for. This is a retrieval run. Treat any bonus loot as a nice extra, not the reason you came.

Finding the Safe in Security Bridge

Once you load into Stella Montis, work towards the northern lobby area and look for the Security Bridge building. The route can vary depending on where you arrive and what is already moving through the facility, so do not force the same path every time. Listen before pushing through doors. If you hear a fight nearby, waiting ten seconds can be safer than charging straight into it. Inside Security Bridge, head up to the third floor. The safe is there, but the first interaction will not get you inside. That is intentional. The clue sits close by on a bulletin board beside a doorway, tucked into the narrow space between the wall and a terminal. It is easy to walk past when you are rushing. Check that spot, read the access information, then return to the safe. Once it opens, take the Project Heartwood Blueprints right away. Do not stand around sorting your inventory beside an open safe. That is how a clean run turns into a messy one.

Leave With the Item, Not Just the Location

Picking up the documents is only the middle of the job. You still have to extract with them and hand them over to Tian Wen. If your loadout has a protected storage slot, use it for the quest item as soon as possible. It gives you a bit more breathing room if another Raider catches you on the way out. From Security Bridge, start thinking about extraction immediately. The building is fairly close to useful exit routes, which is why there is no real upside to lingering. Avoid firing at every target you notice. Noise pulls attention, and attention makes the exit harder. If you have to fight, keep it brief and keep moving. A short detour around a hostile group is often better than proving you can win a long exchange. You will quickly notice that the players who finish this task consistently are not always the best shots. They are the ones who know when to leave.

What the Quest Gives You

Stable Housing pays out with practical kit, including Seeker Grenades, Lure Grenades, and a Snap Hook. None of that changes the map overnight, but each item can make later expeditions feel more manageable. The Snap Hook is particularly handy when you need to reposition instead of taking a direct route through trouble. More importantly, the mission teaches a useful Stella Montis habit: learn one building at a time. Get comfortable with Security Bridge, its stairs, doorways, and nearby exits. On later runs, that knowledge helps when you are looking for crafting materials or other blueprints. Keep a spare loadout ready at home as well. It takes the sting out of a failed extraction and stops one lost kit from slowing your progress for the evening.

Final Thoughts

Stable Housing works best when you keep the plan tight: reach Security Bridge, climb to the third floor, inspect the hidden board, open the safe, and head for extraction. The mission is not complicated once you know the clue location, but Stella Montis can make even familiar routes feel risky when other players or ARC units are nearby. Do not let a successful safe opening tempt you into a long loot run. Secure the documents, deliver them to Tian Wen, and use the rewards to prepare for what comes next. As your stash grows, it can also help to buy ARC Raiders Gear for a replacement setup, so one difficult trip does not leave you starting from scratch.
