Certain items can be a real pain and challenge to find in ‘Arc Raiders’. One you may not know how to get initially is the Sentinel Firing Core, but actually they aren’t that rare, you likely just aren’t looking where they can be found.

Here is a breakdown of where they can be found:
AdvertisementSentinel Firing Cores can be found from the Sentinel turrets you kill. By looting the piece of their hull that drops, you can find them in there.
There are a few key locations where turrets can be found. These include the Control Tower and behind the locked door in the Control Tower on Dam Battlegrounds, the Control Tower in Spaceport, and on the bell towers in Buried City.
You may also find the odd Sentinel Core lying around on Arc Probes and Arc Couriers, so it is worth looting them when you have the opportunity.
Sentinel Firing Cores are one of several important items in the game and as new materials get added with updates they will become just as important, especially when you send your Raider off on an Expedition and have to restart your progression and earn them again. So, next time you can earn them faster.
