U4GM ARC Raiders Stella Montis Blueprint Guide

Walking into Stella Montis for Stable Housing can feel like you are carrying a target on your back. The job sounds simple: find Project Heartwood, get out, hand it over to Tian Wen. In practice, the building is cramped, the routes are busy, and one bad decision can turn a quick errand into a lost run. It helps to treat this as a retrieval mission, not a loot trip. Make room in your pack before you leave, bring supplies you actually know how to use, and remember that ARC Raiders BluePrints are only useful if you make it home with them. You do not need your priciest kit here. A dependable weapon, healing, and a clear exit plan will usually do more for you than showing up overloaded.

Getting to the Security Bridge

Your destination is the Security Bridge building in the northern lobby section of Stella Montis. Getting there is often the easy part, though it depends on where you enter and who else is moving through the area. Keep your ears open. Gunfire, footsteps, and ARC activity can tell you whether it is worth taking a side corridor or waiting for a few seconds. Plenty of players burn through their health before reaching the objective because they stop for every fight or every crate. There is no need. Move with purpose, close doors behind you when it buys time, and do not linger in open spaces. If the route feels crowded, take the quieter way around rather than forcing a fight. You are there for one particular item, and the longer you stay, the more likely somebody notices you.

The Safe Is Not the Whole Puzzle

Once inside Security Bridge, work your way up to the third floor and find the safe. New players sometimes get stuck here because the first interaction does not open it. That is expected. The clue is close by, but it is easy to miss when you are rushing. Look beside the doorway near the safe area, where a bulletin board sits partly tucked between the wall and a terminal. It does not stand out much at a glance, especially if you are watching the hall for movement. Interact with the board to reveal the access information, then head straight back to the safe. This little detour is the heart of the mission. You do not need to sweep every room on the floor, and you do not need to search the rest of the facility. Read the note, open the safe, and pick up the Project Heartwood documents without hanging about.

Protect the Item and Plan the Exit

As soon as the Project Heartwood Blueprints are in your inventory, the mood of the run changes. Now you have something that matters, so play like it. Put the item in a safe pocket if your loadout gives you that option. It is the simplest bit of insurance you can bring. If that is not available, stop grabbing extra loot and start moving toward extraction. Security Bridge is not far from viable exits, but "not far" means very little if another Raider is waiting at the wrong corner. Check your route before committing. Avoid loud fights when you can, and do not chase someone just because they crossed your path. A clean escape is worth more than an extra weapon or a handful of parts. After extraction, return to Tian Wen and turn in the documents to finish Stable Housing and collect the mission rewards, including Seeker Grenades, Lure Grenades, and the Snap Hook.

Final Thoughts

Stable Housing is a useful lesson in how Stella Montis works: know the room you need, carry only what supports the job, and leave once the objective is done. The safe itself is not difficult after you have seen the bulletin board, yet the trip can still go wrong if you treat the area like a casual shopping run. Learn the Security Bridge route, keep a modest backup loadout ready, and save your heavier gear for times when you truly need it. Over a few runs, that habit makes the whole map less intimidating. Stocking up on ARC Raiders Materials between expeditions also gives you more freedom to replace supplies and keep improving your kit for whatever comes next.
