where to find sentinel firing core arc raiders

Sentinel Firing Cores in Arc Raiders are key upgrade items, mainly dropped by specific sniper-like Arc enemies called Sentinels.
Players often hunt these in high-risk areas to level up workstations like the gunsmith to tier 3.

Prime Locations

Dam Battlegrounds stands out as the top farming spot due to reliable Sentinel spawns and fewer enemies overall.
Check the blue exterior staircase at Research & Development, plus both ends of the destroyed dam linking Control Tower and Power Generation Complex—these spots yield chassis drops consistently, even if not every kill guarantees a core.

On the same map, scout the southern corner of the Research and Administration building, roughly central on Battlegrounds.

Other maps offer alternatives:

• Generator Hall fields : Sentinels perch on buildings, sniping downward—watch your flanks.

• Raider's Refuge and Launch/Trench Towers : Ideal overlook positions for these ceiling-mounted threats.

• Bluegate : Near checkpoint areas or tunnels for occasional spawns.

Smart Farming Tips

• Arc Couriers for safer grabs : Forum favorites suggest these carry cores without direct fights—melee or survey them post-down.

• Combat strategy : Crouch behind cover, shoot while reloading; their hits sting hard, so prioritize shields. Chassis often plummet far below.

• Drops aren't 100%—farm husks too, especially on low-Arc Dam runs.
