“Listen up, MacCready. The only reason we haven't filled your body full of bullets is that we don't want a war with Goodneighbor. See, we respect other people's boundaries... we know how to play the game. It's something you never learned.”— Winlock to Robert MacCready
Winlock is a Gunner who is initially encountered at the Third Rail harassing MacCready. He and his friend Barnes will then relocate to the Mass Pike Interchange, an area to which the Sole Survivor must accompany MacCready in order to teach them a lesson.
