Unlike previous games, the Fallout 4 ending cutscene does not change based on how the Sole Survivor has finished most quests or interacted with other people. Only the choice of completing Nuclear Family or The Nuclear Option has any effect on the ending. Also, unlike previous games, the ending is voiced by the Sole Survivor instead of Ron Perlman. Unlike the Fallout 4 intro, the voice is based on the chosen gender.
