The fusion core is an ammunition type in Fallout 76.

Background

This section is transcluded from Fusion core. To change it, please edit the transcluded page.

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]

Characteristics

Fusion cores are used to power and activate suits of power armor and as ammo in certain weapons, such as the Gatling laser, which utilizes fusion cores as its ammunition; each fully-charged core provides 500 shots.
