In 2015, when Naughty Dog was supposed to demo Uncharted 4 at the E3 convention, a cutscene played and then Nathan Drake stood around at the edge of a marketplace, doing nothing. The presenter had failed to find a controller. Now, as you play Chapter 11, you'll witness the cutscene and then Nathan Drake appears in the familiar location. Don't do anything for around 30 seconds and you'll receive a special trophy, which doubles as an Easter egg.
