Fusion cores are an ammunition type in Fallout 4.

Background

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 killing, 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 as well, for use in 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 denote their charge with a value of 1 to 100; the more the cell is used, the lower the charge becomes. Power armor runs on fusion cores. Performing any of the following actions will reduce a core's charge:

  • Running
  • Sprinting
  • Power Attacks
  • V.A.T.S.

Once the fusion core has been emptied, you will move at a reduced rate and will be unable to Power Attack or use V.A.T.S. If the player has another fusion core in their inventory when the current core runs out, it will automatically be installed in the suit. Otherwise, another core needs to be found to restore the power armor's functionality or the suit must be abandoned.

Weapons using this ammunition

The only other item that uses fusion cores as ammunition is the Gatling Laser (Fallout 4).

Locations

  • Fusion cores can often be found in old generators throughout the Commonwealth or purchased from merchants.
  • Pre-War military checkpoints, scattered throughout the Commonwealth.[8]
  • Four fusion cores can be found in Diamond City, in the secret room in Kellogg's house.
  • One fusion core is the reward of Here, Kitty Kitty.
