Companion reactions


  • Even if the player character has finished the main questline by siding with the Brotherhood of Steel, this quest will still be available.
  • Defeating the Brotherhood this way prevents the player character from acquiring unique items, such as Final Judgment or Maxson's battlecoat, because none of the named Brotherhood soldiers show up for this last great battle. However, the coat can still be gained by killing Maxson before the artillery strike.
  • Completing this quest will unlock the ability to use captured Brotherhood Vertibirds with flares found in the Castle armory. About 2 days after completing this quest Preston Garvey will inform you of the captured Vertibirds, any Vertibird Signal Grenades you already have will call the now-Minuteman flown Vertibird
  • If one completed Rockets' Red Glare for the Railroad and then gets Banished from the Institute, this quest will be skipped after completing the Nuclear Option. Preston will be seemingly troubled at the destruction of the Prydwen. He can be reassured that the Brotherhood was a threat.
  • If completing this quest after finishing the main quest line with the Brotherhood of Steel, Liberty Prime will survive the fight and will keep patrolling the Boston Airport, with 5,000,000 HP.
  • There are several Brotherhood soldiers in T-60 power armor armed with laser weaponry along with a fleet of heavily armored vertibirds during this battle.

Behind the scenes

This quest's name is a reference to the children's TV show Captain Planet and the Planeteers. The show follows five super-powered teenagers who can combine their powers to summon the main hero, Captain Planet. When combining their powers, the Planeteers will say any number of phrases that mirror the quest name including "by our powers combined" and "let our powers combine."

    • This can be resolved by finding the last Vertibird around the Boston Airport and destroying it, triggering 100% completion. May also be fixed by reloading a previous save or by running away from the Castle and/or fast traveling to another location.
