Arc Raiders features the Sentinel Firing Core as a rare and valuable item dropped from Sentinels, which are stationary turret enemies positioned on high ground. Defeating a Sentinel requires strategy and precision as they detect movement and fire heavy, single rounds at players within line of sight.

Sentinel Firing Core: Step-by-step guide
Step 1: Scout for Sentinels on elevated positions
Before entering open areas, scan rooftops, ledges, and other high ground for stationary Sentinel turrets. Their silhouette is distinctive, and they guard these vantage points overlooking key outdoor spaces.
Step 2: Use cover to dodge Sentinel shots
Find solid cover near the Sentinel to break its line of sight. When its converging laser beams merge on you, immediately move behind cover or dodge roll to avoid the heavy sniper shot. Stay mobile by strafing and sprinting to reduce the chance of being hit.
Step 3: Aim for the small yellow weakpoint capsule
Sentinels have no armor but have a small vulnerable yellow capsule on a swiveling arm. Focus all your shots here with medium or heavy rounds for maximum damage efficiency and to reduce fight duration.
Step 4: Collect the Sentinel Firing Core and other loot
Once destroyed, the Sentinel will drop valuable loot including the Sentinel Firing Core, Advanced ARC Powercell, and Heavy Ammo. Approach and pick up all dropped items to add to your inventory.

Additional tips
- Sentinels do not respawn in the same raid but reset after raid completion, so memorize spawn points to repeatedly farm Cores across raids.
- Combine farming Sentinels with other resource objectives in a raid to maximize efficiency and gather multiple materials in one run.
- Keep an eye on your ammo type and quantity—mid to high tier ammo is vital for Sentinel kills but melee can help save bullets once close.
Mastering the hunt for Sentinel Firing Cores is a strategic path to accelerate your progress in Arc Raiders. It balances risk and reward by requiring cautious navigation of high ground under turret fire while offering one of the most lucrative single-item drops for crafting and upgrading weapons. Whether you aim to build your arsenal or stash Raider Coins, knowing when to recycle, salvage, or sell the core optimizes your resource management for tougher challenges ahead.
