How to Get Sentinel Firing Core in ARC Raiders

ARC Raiders is a third-person extraction-shooter that combines PvE and PvP elements. Players drop into raids to scavenge resources and salvage gear while facing ARCs and other players. After extracting successfully, you return to your underground base, where you can upgrade workbenches to craft higher-tier equipment and weapons.

The Sentinel Firing Core is an advanced material required for upgrading specific workshops to Level 3. The Gunsmith, for example, needs 4 Sentinel Firing Cores alongside other components to reach its final upgrade tier. Without these cores, you can't unlock top-tier weapon crafting capabilities.

The game doesn't clearly explain where to find Sentinel Firing Cores or which enemies drop them. In this article, we'll explore exactly how to get Sentinel Firing Cores in ARC Raiders, covering the most reliable farming methods and locations.

Where to Find Sentinel Firing Core

Sentinel Firing Cores drop exclusively from Sentinel ARCs, a specific enemy type that uses long-range attacks. The key detail is identifying the correct Sentinel ARC variant. Two types exist that look identical but use different weapons.

One fires multiple bullets rapidly like a minigun, while the other shoots single, powerful shots like a sniper rifle. You need to target the sniper variant specifically, as only this version has a chance to drop Sentinel Firing Cores.

ARC Husks also drop Sentinel Firing Cores under certain map conditions. These are the destroyed remains of ARCs scattered across the map. Not every Husk contains loot, but checking them during your raids adds another potential source for this material.

Sentinel ARC Locations

Sentinel ARCs spawn randomly across multiple maps in ARC Raiders. The spawns aren't fixed, meaning their exact location changes between raids. However, they consistently appear in specific map zones where you can patrol and hunt them down.

The three main maps where Sentinel ARCs spawn are:

• Dam Battlegrounds

• Buried City

• Spaceport

Each map has distinct zones where Sentinels are more likely to appear. The random spawn system means you won't find them in the exact same spot every raid, but they stick to general regions within each map.

1. Dam Battlegrounds

Sentinel ARCs can spawn in three different locations every raid on Dam Battlegrounds. The spawns rotate randomly, so you won't find them in all three spots during a single run. Here are the locations:

• Near the entrance of the Research & Administration building

• North of Floodgates

• North of the Breach

Check each location systematically when farming Sentinel Firing Cores. Start with the Research & Administration building entrance since it's often a central point on the map, then move north toward Floodgates and the Breach area. The Sentinel might appear in any of these zones, so patrolling between them increases your chances of finding one.

2. Buried City

Sentinel ARCs spawn in two different locations on the Buried City map. Here are the locations:

• Inside the Town Hall

• West of Piazza Arbusto, under the bridge

Check both locations during your raids. Buried City's layout makes it easier to rotate between these two spots compared to the more spread-out Dam Battlegrounds spawns.

3. Spaceport

Sentinel ARCs have the most spawn locations on Spaceport compared to other maps. Six different zones can host these enemies during any given raid:

• Inside Rocket Assembly

• North and South Trench Towers

• East side of Control Tower A6

• Inside Container Storage

• Southeast of Fuel Lines

• South of the Departure Building

Spaceport's larger map size spreads these spawns across significant distances. Checking all six locations in a single raid isn't practical, especially with the time limit and other players competing for the same targets. Focus on clusters of spawns that are close together.

Final Words

Sentinel Firing Cores drop from the sniper variant of Sentinel ARCs found across Dam Battlegrounds, Buried City, and Spaceport. The spawns rotate randomly, so check multiple locations during each raid. Focus on the sniper-type Sentinels instead of the minigun variants, and prioritize maps with more spawn points, like Spaceport, for efficient farming. ARC Husks under certain map conditions provide additional chances for drops.
