In the ongoing struggle for survival against the robotic onslaught on the Topside, high-tier crafting components are the lifeline of any successful Raider. Among the most vital and elusive of these materials is the
Sentinel Firing Core. This rare drop is absolutely necessary for upgrading your essential
workstations in
ARC Raiders, allowing you to unlock powerful weapons and gear blueprints.The Sentinel Firing Core is notoriously difficult to secure because it only drops from specific, powerful enemies—the
Sentinels—or from rare ARC husks. Finding these enemies requires precise knowledge of the map, and farming them is a dangerous endeavor.If you’re ready to stop relying on luck and start strategically farming this component, this comprehensive guide will detail the best location, the exact enemy spawn points, and the necessary techniques to maximize your Sentinel Firing Core haul.
Arc Raiders: Get A Sentinel Firing Core
Targeting the Source: Sentinel Enemy Spawns
The most direct way to acquire a Sentinel Firing Core is by destroying the namesake enemy: the
Sentinel. However, this item is a
rare drop, meaning you will likely need to eliminate several Sentinels before securing a Core.
The Best Map for Sentinel Hunting: Dam Battlegrounds
Donate: buy me a coffeeWe've found that the Dam Battlegrounds map offers the mostaccessible and relatively consistent opportunities for farmingSentinels. This is due to a good balance of loot density and specificspawn points that are easy to target immediately upon dropping.
Sentinel Hotspot: Research & Administration POI
The most reliable spot to encounter a Sentinel enemy is at the Research & Administration Point of Interest (POI) on the Dam Battlegrounds map.
- Exact Location: Look for the main building within the POI. A Sentinel is typically located on the side of this building, positioned just at the top of the staircase on the corner.
- Engagement Strategy: Since this is a busy part of the map, attracting both Raiders and other ARC units, it is highly recommended to destroy the Sentinel from a distance. Use armor-piercing weapons to take it down quickly, then advance to salvage the husk.
- Looting Tip: Once destroyed, walk up and salvage the ARC husk. While the Core is a rare drop and may not always appear, this is yourbest chance. If you don't find the core immediately, sometimes theprimary body of the Sentinel will fall to the very bottom floor, so besure to check all levels.
Caution: Never forget that the Research & Administration POI is a high-traffic zone. Be prepared for a fight against rival Raiders who are also likely scavenging the area or fighting other ARCs.
Alternative Farming Method: Looting ARC Husks
If direct Sentinel hunting proves too risky, or if you prefer alower-intensity scavenger hunt, you can also find Sentinel Firing Coresby looting general destroyed ARC husks scattered across the map.
ARC Courier Husks Hotspot: Swamp Outpost
We have also found numerous Sentinel Firing Cores—alongside other valuable components like Wasp Drivers and Fireball Burners—by focusing on specific types of husks, namely the ARC Courier Husks.
- Map Location: Head toward the Swamp Outpost area on the Dam Battlegrounds map.
- Target Spawns: Look for the smaller ARC Courier husks concentrated around the larger Baron husks located to the north of the Swamp Outpost POI.
- Strategy: These husks offer a chance at a variety of random ARC loot.Meticulously search every husk in this area. While the drop rate isstill low, the high density of husks makes this a worthwhile detour forgeneral material farming with a chance at the Core.
Optimizing Your Core Farming Strategy
To make your raids as efficient and safe as possible while hunting the Sentinel Firing Core, remember these key takeaways:
- Don't Recycle: If you find a Sentinel Firing Core while looting general crates or scavenging a husk, do not recycle it for materials. It is far too valuable for workstation upgrades.
- Use Armor Penetration: Sentinels are tough. Bring weapons with strong armor-piercing capabilities (rifles or high-powered shotguns) to ensure you destroy them quickly and conserve ammunition.
- Plan Your Extraction: Since the Sentinel Firing Core is rare, successfully extracting it is paramount. Have a clear, quick path to your extraction point planned once you secure the item.
- Prioritize Dam Battlegrounds: Due to the clear location of the Sentinel at the Research &Administration POI and the density of husks near Swamp Outpost, the Dam Battlegrounds map is currently the easiest place to dedicate your farming runs.
By strategically targeting the Research & Administration Sentinel ormeticulously scavenging the husks near Swamp Outpost, you cansignificantly increase your chances of finding the Sentinel Firing Coreand quickly upgrade your weapons and gear for the Topside.
