Nucleus

Fallout 4 guide · infiltrating the Children of Atom base
← All areas in this guide

The Nucleus is a converted pre-war submarine base on the island of Far Harbor serving as the headquarters for the Children of Atom. To enter peacefully, the player must complete a trial in the glowing spring outside to gain the trust of the zealots. Inside, you can interact with the cult's leadership, advance main faction quests, access DiMA's hidden memory banks, or choose to completely destroy the facility using the submarine's launch controls.

Shops and people

  • Brother Kane: Radium rifles, zealot armor, ammunition, and standard weapons
  • Sister Mai: Marine armor modifications, heavy weapons, fusion cores, and miscellaneous technical junk

Tips

  • Wear a Hazmat Suit or fully upgraded Power Armor before exploring, as the central pool and several maintenance tunnels contain severe radiation fields.
  • Buying the Kiloton Radium Rifle early is highly recommended, as it deals explosive ballistic damage alongside radiation damage.
  • If you decide to initiate the nuclear detonation sequence to wipe out the base, you must escape within thirty seconds before the reactor explodes.
