Fusion Cores can sometimes be looted from generators found across the world map, but there is only one place in Appalachia to get a decent supply, and that is camping the Poseidon Energy Plant and using the Workshop there to generate Fusion Cores.This can be time and resource consuming, assuming someone else hasn’t capped the Workshop and surrounded it with a dozen turrets to make players think twice about taking their turf. While Power Armor is the top name in protection in Fallout 76, it comes with the drawback that using it requires a resource that for some players may be hard to come by.
