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.
