How to get Fusion Cores in Fallout 4

The lifeblood of Power Armors: sought by many, acquired by few.

In the desolate wasteland of Fallout 4‘s Commonwealth, Vault Dwellers and scavengers search for the most scarce resource: Fusion Cores. These Fusion Cores are batteries that power up the hulking Power Armor sets, transforming them into an unstoppable force of annhilation.

Since there’s no way to recharge these Fusion Cores, players must venture out on a search to find them for their Power Armors. Sure, players can spend a chunk of bottlecaps with vendors to easily acquire a few Fusion Cores, but the Commonwealth is a huge wasteland where retailers for this source of energy are hard to find.

That is why we’ve taken the liberty to list down a bunch of locations where players can score some free Fusion Cores in Fallout 4.

Other ways of getting Fusion Cores in Fallout 4

For players who’ve combed every corner of the wasteland or don’t feel like straying too far from their settlements, there are plenty of other ways to get a hold of Fusion Cores in Fallout 4.

One of the ways is to purchase them directly from vendors that specialise is ammunition, such as Alexis Combes in Vault 81. Vendors usually have a stock of around five fully charged Fusion Cores at a time available for sale.

Another way of acquiring Fusion Cores is by speaking with the Robert MacCready. Recruit the resillient comapnion and have a polite conversation with him to be rewarded with a few cores.

Aside from speaking with companions or purchasing Fusion Cores from vendors, players can also complete a bunch of side quests that give them access to this scarce resource. For instance, completing the Here Kitty, Kitty quest in Vault 81 earns players one Fusion Core.

Lastly, if all things fail, players can always pickpocket The Brotherhood of Steal members or destroy sentry robots to acquire a few extra Fusion Cores for their Power Armor suits.
