Where to Find Every Fusion Core in Fallout 4 (With a Map & Console ID)

Recently, I've been playing a new immersive Fallout 4 survival experience with no HUD, V.A.T.S., or crosshair (live playthrough on YouTube), and as a low-level character, I've realized that I need more fusion cores. The game is extremely difficult at first, so power armor is more of a necessity than a fashion statement. Then it occurred to me to create this guide to assist both myself and you, as I cannot be the only one in need. I've compiled a list of every location (with a map) that includes fusion core, as well as the console ID, below.

Listen to this article!

Since a fusion core provides approximately 20 minutes of real-time (or approximately 10 hours of game time) power armor use when jogging (at the default pace), we clearly need a lot of them. The Gatling laser utilizes fusion cores as its ammunition, each core providing 500 shots. Nuclear Physicists can increase the number of shots per core to 1000, but magazine capacity remains at 500.

In addition to the fixed locations listed below, fusion cores may spawn in groups of four in specific ammo boxes throughout the Commonwealth. Cores can be spawned in other container types using an eyebot pod, but only one at a time.
