This guide covers every known Sentinel spawn location, how to spot them from a distance, workarounds for common bugs, and strategies for taking them down efficiently. Whether you’re running Dam Battlegrounds or exploring Spaceport, you’ll know exactly where to search.
All Sentinel Spawn Locations
Sentinels are stationary turret-type ARC enemies that usually spawn in elevated positions overlooking open areas. They don’t appear in every raid, and spawn locations are not guaranteed.

You may need to run several raids before finding one at a particular spot. If a Sentinel hasn’t spawned at your target location, consider checking alternative spots on the same map or extracting and trying again.
Dam Battlegrounds
Dam Battlegrounds is the most reliable map for farming Sentinel Firing Cores, with three potential spawn points. This makes it the go-to destination for most players hunting cores.

Look for the Sentinel positioned on elevated terrain scanning the area below. This location spawns consistently and offers decent cover for approaching.
The second spawn is at the Research and Administration Tower. Check the right corner of the building above the staircase. You can approach from the industrial buildings nearby to use them as cover while engaging.
The third spawn is between the significant breach in the dam wall. If the Sentinel doesn’t appear at Research and Administration, two can spawn in this area instead. However, note that the spawn near the staircase is known to be buggy and may cause issues when the Sentinel is destroyed.
Spaceport
Spaceport has the highest number of potential Sentinel spawns with six locations across the map. Look for elevated catwalks and ledges near the hangars and the main runway area.

Check rooftops and any elevated platforms overlooking open ground.
Buried City
Buried City offers several Sentinel spawn points, though they appear less frequently than on Dam Battlegrounds. The Town Hall near the center of the map is a known spawn location. Look for the small arch where a bell would normally hang, as Sentinels can appear on this rooftop.

Blue Gate
Blue Gate has two Sentinel Turret spawn locations. One spawns on the left side of the map, and another can appear on the very right edge.

Stella Montis
Sentinels do not spawn on Stella Montis, and so it is recommended to farm using other maps.
Riven Tides
There isn’t much community data for Sentinel Firing Core on Riven Tides yet. Sentinels have 3 reported spawn points on Riven Tides, and ARC Couriers and husks here can hold them too. This area is on the quieter side, which makes for a calmer run.

Containers hold more than one thing, so here’s what else is worth grabbing on the same run.
The ARC Couriers and Wasp husks that hold Sentinel Firing Core, most often on the Spaceport and Riven Tides, also roll:
- Leaper Pulse Unit (10 needed for Trophy Display phase 3, 4 for Utility Station Level 3)
- Surveyor Vault (5 needed for Trophy Display phase 1, 5 for Medical Lab Level 3)
- Tick Pod (15 needed for Trophy Display phase 1, 8 for Medical Lab Level 2)
- Wasp Driver (20 needed for Trophy Display phase 2, 8 for Gunsmith Level 2)
What Is a Sentinel Firing Core
The Sentinel Firing Core is a rare crafting material that drops from Sentinel turrets when destroyed. It weighs 1.0, stacks up to 3 per inventory slot, and sells for 3,000 coins if you choose to recycle it at vendors.
Your primary use for this item is upgrading the Gunsmith Station. The level 3 upgrade requires 4 Sentinel Firing Cores, 3 Rusted Gears, and 5 Advanced Mechanical Components. Without this upgrade, you’re locked out of higher-tier weapon modifications.
If you decide to recycle Sentinel Firing Cores instead, you receive 3 Mechanical Components and 2 ARC Alloy. Salvaging yields 2 Mechanical Components. However, given how difficult it is to obtain these cores, upgrading your Gunsmith should take priority. Afterward, they aren’t used for anything, so recycle or sell them.
How to Spot Sentinels Quickly
Sentinels give away their position before you even get close. They use orange laser targeting beams that track player movement across long distances. If you see a laser sweeping an area or an orange laser tracking toward you, a Sentinel is nearby.
Their range is vast, meaning the blue line can also be seen from far away. Sentinels are essentially Sniper Turrets; they can lock onto you and fire Heavy Ammo rounds at your position. The laser converges before it shoots, giving you a brief warning to find cover.
To save time while farming, use binoculars to scout spawn locations from afar if the blue line can’t be seen. This prevents wasted trips to empty spawns. If you can’t spot a laser or the Sentinel itself through binoculars, the spawn point is likely empty, and you can move to another location instead.
Binoculars can be bought from the Traders District, from Shani – Security for 1,920 Coins, from free loadouts, or crafted in the Utility Station, which requires 8 Plastic parts and 4 Rubber parts.
Known Bugs and Workarounds
Sentinels have notoriously bad physics when destroyed. Their bodies can launch unpredictably when they take the killing blow, sometimes flying significant distances from where they were stationed. Keep your eyes on the Sentinel as you fire the final shot and follow the direction it gets flung.
The most frustrating bug occurs when a Sentinel’s body clips through the map, making the loot completely unreachable. The spawn near the staircase on Dam Battlegrounds is particularly prone to this issue. The terrain causes destroyed Sentinels to fall under the map at higher rates than in other locations.
If you experience this bug repeatedly at a specific location, try different approaches. Killing the Sentinel from a different angle can change how the physics interact with the terrain. Using different weapons with varying knockback effects may also help. Some players report better results with precision weapons that don’t cause as much ragdoll movement.
When possible, try to destroy Sentinels in a direction that it gets hypothetically flung to a flat ground rather than towards hills, stairs, or uneven surfaces. This reduces the chance of the body falling into geometry where you can’t loot it.
Alternative Method: ARC Courier
You don’t have to kill Sentinels to get their Firing Cores. ARC Couriers are large, chest-like containers scattered across all maps that can contain Sentinel Firing Cores and other ARC parts.
Look for black smoke rising from the ground, which indicates either a downed ARC, a crashed probe, or an ARC Carrier. One player reported finding 3 cores in just 2-3 runs by focusing on looting these carriers, making it a viable alternative when Sentinel spawns aren’t cooperating.
Sentinel Drops and Loot
When you successfully destroy a Sentinel and loot its hull, you can receive multiple valuable items. The confirmed drop pool includes the Sentinel Firing Core, ARC Alloy, Advanced ARC Powercell, ARC Coolant, ARC Synthetic Resin, ARC Thermo Lining, ARC Motion Core, and Heavy Ammo.
The Sentinel Firing Core is not a guaranteed drop from every kill. You may need to destroy multiple Sentinels before obtaining all four cores required for your Gunsmith upgrade. Each successful loot is worth the effort, so always extract with your cores or store them in a safe spot if you have an augment that provides one.
How to Kill Sentinels
Sentinels are classified as high-threat enemies with 300 health points, but they’re unarmored. They hit hard with Heavy Ammo rounds, but their slow reaction time and fire rate work in your favor. Usually takes a few hits before being killed
If the laser is blue, it means it is unaware of your presence. If the laser is orange, it indicates that the laser has detected a potential threat nearby but is unsure of its exact location; it will be searching for the threat. If the laser is red, it means the laser has located the threat.
The weak point is the yellow capsule attached to the rear of the swiveling arm. Hitting this causes massive damage and can destroy the Sentinel quickly. Aim for this yellow target when you have clear shots.
Use cover extensively. The Sentinel’s slow reaction time means you can pop out, take shots, and return to cover before it fires. Dodge rolling and sliding also help avoid incoming rounds if you’re caught in the open. Breaking the line of sight for extended periods causes the Sentinel to lose track of you.
Bring healing items when hunting Sentinels. Their damage output is significant, and other players may third-party you during the fight. These spawn points are often contested, especially on Dam Battlegrounds, where Sentinel farming is more common / appears in high foot traffic areas.
For increased spawn rates, consider running Night Raids. Night Raids spawn more ARC enemies overall, including Sentinels. The tradeoff is reduced visibility and potentially more dangerous encounters with other ARC types.
To ensure completely safe runs, bring Lure Grenades and throw them in its line of sight. This lets you fire at it without any concerns.
Frequently Asked Questions
How many Sentinel Firing Cores do I need for the Gunsmith upgrade?
You need 4 Sentinel Firing Cores to upgrade the Gunsmith Station from level 2 to level 3. The upgrade also requires 3 Rusted Gears and 5 Advanced Mechanical Components.
What is the best map for farming Sentinel Firing Cores?
Dam Battlegrounds is the best map with three potential Sentinel spawn locations. Spaceport has six possible spawns but covers more ground. For efficiency, Dam Battlegrounds offers the best balance of spawn density and manageable map size.
Why did the Sentinel disappear when I killed it?
Sentinels have buggy physics that can cause their bodies to clip through the map when destroyed. This happens more often near stairs, edges, and uneven terrain. Try killing Sentinels on flat ground and from different angles to minimize this issue.
Are Sentinel spawns guaranteed every raid?
No, Sentinel spawns are not guaranteed. You may need to run multiple raids before finding one at a specific location. Use binoculars to scout spawn points from a distance to avoid wasting time traveling to empty spawns.
Can I get Sentinel Firing Cores without fighting Sentinels?
Yes, you can find Sentinel Firing Cores in ARC Carriers scattered across all maps. Look for black smoke rising from the ground to locate these chest-like containers.
What is the Sentinel’s weak point?
The yellow capsule on the rear of the Sentinel’s swiveling arm is its weak point. Hitting this deals massive damage and can destroy the Sentinel quickly.
Do Night Raids have more Sentinels?
Night Raids increase the overall number of ARC spawns, including Sentinels. Running Night Raids can improve your chances of finding Sentinels, though visibility is reduced and other enemies become more dangerous.
Should I sell or keep Sentinel Firing Cores?
Keep your Sentinel Firing Cores for the Gunsmith upgrade. While they sell for 3,000 coins and recycle into 3 Mechanical Components plus 2 ARC Alloy, the cores are difficult to obtain and essential for unlocking better weapon modifications.
I’ve personally tested and can vouch for each location listed, having found a Sentinel Firing Core in any locations mentioned across hundreds of hours of personal gameplay.
