Nuclear Family is the final Institute main quest and achievement/trophy in Fallout 4.

Walkthrough Edit

Return to the Institute to speak with Father and listen to his final words before he dies of end stage cancer. Shown next are glimpses of the player character's life prior to the war and their experiences since.
