A fusion core is a type of ammunition in Fallout 4 and Fallout 76.

Background[edit | edit source]

Standardized fusion cores are a high-grade, long-term nuclear battery used for military and commercial applications before the Great War.[1] Used by civilians to power a multitude of devices, from automobiles,[2] to generators,[3] the military instead used them for warfare, supplying power armor and some Gatling laser models with energy. Standard core interfaces were developed across the board to allow for power armor frames to use cores salvaged from weapons or generators.[4] The fusion core also can be hooked up to certain melee weapons via jumper cables.[5] A specialized variant of the fusion core was developed for use in certain plasma weapons.[6]

Another benefit is that cores can be set to overload, for use as improvised explosives or to deny a power armor suit to the enemy by destroying it.[7]

Variants[edit | edit source]

    Preston Garvey: "What you'll need is an old pre-war F.C., a standardized Fusion Core. Your high-grade, long-term nuclear battery. Used by the military and some companies, way back when. And we know right where to find one..."
    Sturges: "But we can't get to the damn thing. It's down in the basement, locked behind a security gate. Look... I fix stuff. I tinker. Bypassing security ain't exactly my forte. You could give it a shot."

    Preston Garvey: "A Fusion Core. It's kind of a fancy battery. They used one here in the museum to power the exhibits, a long time ago. There's one in the basement, behind a security gate. You'll need to pick the lock or hack the computer to open it."

  4. Sturges: "That armor may be old, but it's got a standard interface. Just jack the Fusion Core in."
