Where to Find Sentinel Firing Cores: Best Locations in Arc Raiders

1. Dam Battlegrounds: Research & Administration Building

The Dam Battlegrounds is one of the best places to find Sentinel Firing Cores. These turrets spawn near the Research & Administration Building. To find them, head to the south side of the building and look for a staircase. Once you’re up, the Sentinel Turret will usually be in the corner, sniping at you. Take cover and shoot it down from a safe distance.

After destroying the Sentinel, make sure to loot it to get the Sentinel Firing Core. However, be cautious of a bug where if the Sentinel falls down, it may disappear, making it impossible to loot the core. While this is frustrating, keep trying—when you succeed, you'll get the core you need.

2. Alternative: Arc Couriers

If you want to speed up the process, Arc Couriers are another great source for Sentinel Firing Cores. These crashed Ark vessels are scattered across various maps, and when you breach them, they often contain Sentinel Firing Cores. You’ll know you’ve found an Arc Courier when you see smoke rising from the wreckage.

The Arc Courier method is likely the easiest way to farm Sentinel Firing Cores, as these vessels can spawn on almost every map and the cores inside them are much easier to find than trying to track down the Sentinel Turrets. If you're near one, don’t miss the opportunity to loot it!

3. Buried City: Town Hall Roof

The Buried City map also offers a chance to find a Sentinel at the Town Hall. You’ll need to make your way to the rooftop, where there’s usually a bell—but instead of a bell, you’ll find a Sentinel. This spot doesn’t have a high spawn rate; it’s seen about once every 10 runs.

Once you take down the Sentinel, the core is likely to fall off the roof and into the sand. Be mindful of enemies patrolling the area—it can be tough to grab the core when there’s a threat nearby, but if you manage to loot it, you’ll have one more Sentinel Firing Core in your collection.

4. Spaceport & Blue Gate: Possible Spawn Locations

Other reported locations for Sentinel Firing Cores include the Spaceport and Blue Gate maps. On Spaceport, the Sentinel may spawn near the checkpoint or big antenna. However, after trying this spot for 10 runs, I can confirm I haven’t seen the Sentinel spawn there yet.

Similarly, on the Blue Gate map, the Sentinel can spawn in the top right corner or near the checkpoint. Again, these spawns are rare, so don’t be discouraged if you don’t find one on your first few attempts.

How to Maximize Your Sentinel Firing Core Farming

To maximize your farming efforts, here are a few tips:

• Loot Arc Couriers: These provide a more consistent and reliable source for Sentinel Firing Cores.

• Farm Dam Battlegrounds: If you want to take on Sentinel Turrets, focus on the Research & Administration Building.

• Check Rare Locations: Don’t forget to check the Buried City and the Spaceport for Sentinel spawns, even though they’re rare.

By following these tips, you’ll have a better chance of collecting Sentinel Firing Cores quickly and efficiently.
