If you’ve been grinding through Arc Raiders lately, you’ve probably run into the Fragmented Logs side quest. It is one of those multi-step missions that can feel incredibly frustrating if you don’t know exactly where you are going, especially with machines patrolling every corner.
The good news is that you don't have to get everything done in a single run. If you manage to finish the first part and get taken out later in the match, your progress carries over. Even better, you don't even need to successfully extract at the end to get credit for the quest.
If you are ready to check this one off your list, here is a straightforward, step-by-step breakdown of how to get it done.
Before You Deploy: What to Bring
Before you choose the Stella Montis map, check your stash. You are going to need exactly 1 Electrical Component to complete the very first step.
If you have one lying around in your storage, put it in your inventory before matchmaking. If you don't have one, don't sweat it too much—you can loot them while you're out there in the world, but bringing one along saves you a ton of time and let's you hit the ground running.
Step 1: Repair the Out-of-Service Terminal
Once you are on the ground in Stella Montis, your first destination is the Robotic Sandbox. This area is pretty massive, but you are looking specifically for the Control Rooms that overlook the main testing chambers.
Head up to the upper overlook area flanking the chambers. Inside the control room, you will find a faulty, out-of-service computer console. Walk up to it, interact with it, and slot in that Electrical Component you brought with you. That will instantly clear the first objective.
Step 2: Enable the Conduit Power
With the terminal repaired, it's time to head downstairs. Move down to the ground floor layers of the sandboxes, keeping an eye out for the metro tunnels and ramps.
You are looking for an alcove or backroom labeled either Control Room A3 or Control Room B2. Once you find the right alcove, step inside and look between the rows of server banks. There is a large Main Power Switch mounted directly on the wall. Flip that switch to restore power to the conduit and wrap up the second part of the quest. You don't need any special items for this step—just a clear path to the wall.
Step 3: Boot the Mainframe Terminal
The final step requires you to move across the map over to the far east section, where the Cultural Archives structure is located. This is the trickiest part of the quest because the archives are usually crawling with Shredders.
You'll need to use a bit of situational awareness here. Either clean out the Shredders roaming the hallways if you have the firepower, or carefully sneak past them if you're running solo or low on ammo. Look for a small, cramped back room filled with servers. Inside, you'll find the primary mainframe terminal. Interact with the console to lock in the logs, and the quest is officially over.
The Rewards
The exact moment you hit the switch on that final mainframe terminal, the quest completes. Even if an enemy squad or a stray drone catches you right afterward, those rewards are safely yours.
For your trouble, you will immediately unlock:

• 3 Showstopper Grenades: These are incredibly useful for tight situations, as they will completely stun both ARC machines and hostile Raider enemies.
• 3 Trailblazer Items: Great for boosting your progression and keeping your inventory stocked.
