Sentinel Firing Core locations in ARC Raiders

All sorts of items are required to progress in ARC Raiders, but none are as challenging to obtain as those associated with the different (and dangerous) ARCs.

The Sentinel Firing Core is one such item, usually dropped by, as the name implies, Sentinels—powerful, long-range ARCs that can take you out in a single shot. Thankfully, fighting them isn’t necessary to get the Firing Cores, even if they do consistently drop them.

Here’s where you should look.

How to get Sentinel Firing Cores in ARC Raiders

The absolutely best and easiest map for farming Sentinel Firing Cores is Dam Battlegrounds. This item can both be found in ARC Couriers (smaller drop rate, but no fighting required) and Sentinels themselves.

ARC Couriers tend to spawn in the northern portion of the map, where players, too, usually start their matches. You’ll commonly find them off the highway among the rocks above the Hydroponic Dome Complex, or east between the Complex and the Dam itself. Of course, there’s more on top of the Dam, across from the Power Generation Complex and near the Pipeline tower.

These are random spawns, so they may or may not be there, though I reckon at least one or two will spawn in these areas.

On the other hand, you can fight the Sentinels themselves for the loot. In the Breach section of the Dam, where a crashed Baron lies, two Sentinels tend to spawn on either side of the wall. At least one of them will be in almost every match, though it can be a bit hard to reach.

For that reason, it might be better to rush for the Red Lakes region and climb the stairs toward Research and Administration, as one or two Sentinels will spawn near the top overlooking the stairs. This one is much easier to reach and loot.

Keep in mind that neither Couriers nor Sentinels have a guaranteed drop of Sentinel Firing Cores, but you should get all you need within a few matches (provided you aren’t killed in the process, which is just a fact of life in ARC Raiders).
