FO4/FNV crossover: John McDonough wasn't always Hancock or a ghoul. After his brother is elected mayor and kicks all the ghouls out of Diamond City, John tries to help as many as possible adjust to life in Goodneighbor. Eventually he makes his way to Vegas, where he runs into Courier Six, a ruthless woman with a bullet in her brain, a chip on her shoulder, and a Strip to liberate.
