If you\u2019re on the hunt for ARC Raiders Sentinel Firing Cores, you\u2019ve got two main routes: grind them out in-game or buy them from a fellow player who is stocked up to the brim. Grinding is RNG-heavy and eats a ton of time, as you\u2019ll need Sentinel Firings Cores for several things.<\/span><\/p>\n

Read on to learn where to look for Sentinel Firing Cores in-game and how to get them ASAP.<\/p>\n

What is an ARC Raiders Sentinel Firing Core, and why do you need it<\/span><\/h2>\n

Sentinel Firing Cores<\/b> are rare crafting drops, mostly from Sentinel ARC turrets and ARC Courier husks. You need four to upgrade your Gunsmith to tier three, which upgrades <\/span>weapons<\/span><\/a> and recipes<\/span><\/a>.<\/span><\/p>\n

No cores means being stuck with lower-tier gear while the competition gets ahead. They\u2019re rare drops, and farming them could become a grind.<\/span><\/p>\n

Dam Battlegrounds<\/b> is the meta map for farming. With some luck, you’ll spawn next to the Research & Administration zone. The best spawn is at the corner of the Dam Control Tower Administration building, near the blue stairs. Snipe the Sentinel from range, but be ready to loot the lower floor if the core drops down.<\/span><\/p>\n

If that one\u2019s missing, hit The Breach in the dam wall. Up to two Sentinels can pop there.<\/span><\/p>\n
