How To Get A Sentinel Firing Core In Arc Raiders

Sentinel Firing Cores are one of those items in Arc Raiders that you probably ignored early on, until the game suddenly demands one and turns it into a real hunt. This rare component is tied to tougher enemies and higher-risk areas, meaning you won’t just stumble across it while looting random containers. Whether you need it for crafting, upgrades, or a project requirement, knowing where it drops and how to get it safely can save you a lot of failed runs. In this guide, we’ll break down exactly what a Sentinel Firing Core is, where it comes from, and the best way to secure one without throwing your loadout away.

Where To Find A Sentinel In Arc Raiders

The most reliable way to hunt Sentinels for a Sentinel Firing Core is on the Dam Battlegrounds map, which consistently offers the safest and most predictable spawns. One of the easiest Sentinels to farm sits on the outer corner of the Research & Administration building, right at the top of the staircase along the wall. You can take it out from range without pulling extra ARC aggro, then move in to loot the wreckage for a chance at a Sentinel Firing Core, though keep in mind the drop is rare and not guaranteed. In some runs, the core may not drop at all, and the Sentinel’s remains can occasionally fall to a lower floor, so it’s worth checking the ground level before leaving. If this spawn doesn’t appear, two Sentinels can also show up near the large breach in the dam wall on the same map, making Dam Battlegrounds the best overall choice for repeat farming. Outside of that map, Spaceport has several Sentinel spawn points, including the Fuel Lines wall, Control Tower A6, Container Storage, Rocket Assembly, and both trench towers, though these areas tend to attract more players and ARC patrols. Buried City has fewer but notable spawns on the bridge near Grandioso Apartments, at the Town Hall entrance, and on the bridge by Plaza Arbusto, while Blue Gate offers Sentinel locations at the Outer Gates wall, the edge of the Headhouse, and the tower at Pilgrim’s Peak. If you want the lowest risk and quickest resets, Dam Battlegrounds remains the best place to consistently hunt Sentinels without turning every run into a PvP nightmare.

Best Place To Loot A Sentinel Firing Core

Another solid way to get your hands on a Sentinel Firing Core is by looting ARC Courier husks, which can occasionally drop them alongside other valuable ARC materials. These husks appear across every map, but Dam Battlegrounds stands out as the most reliable place to farm them due to how many spawn in close proximity. One of the best areas to check is around Swamp Outpost, especially north of the point of interest where larger Baron husks tend to appear. Scattered around these are several smaller ARC Courier remains, and each one has a chance to drop rare loot like Sentinel Firing Cores, Wasp Drivers, Fireball Burners, and similar components. While the drop rate isn’t guaranteed, this method is much safer than hunting active Sentinels and doesn’t require a full fight. ARC Couriers can show up on any map, so it’s always worth watching for smoking ARC wreckage and keeping an eye on your map for nearby highlights. With a bit of patience, this approach can pay off fast, as it usually only takes a handful of runs to collect all the Sentinel Firing Cores you need.

Conclusion

Getting a Sentinel Firing Core in Arc Raiders mostly comes down to knowing where to look and choosing the safest approach for your playstyle. Farming Sentinels on maps like Dam Battlegrounds is the most direct method, while looting ARC Courier husks offers a lower-risk alternative that can still pay off with some patience. Since the drop isn’t guaranteed, planning a few focused runs and avoiding unnecessary fights can save you a lot of time and gear. With the right routes and a bit of persistence, you’ll be able to secure a Sentinel Firing Core and move forward with your crafting or event progress without too much trouble.
