We all knew Naughty Dog had a sense of humor, and after watching the latest gameplay footage of The Last of Us at E3 2012, it looks like they really wanted to give a shout out to Uncharted's Drake.
The subtlety of this "in-joke" would only make sense to hardcore gamers and those who follow the industry. The character of Nathan Drake has become inseparable from his trademark half tuck shirt, and was apparently a late addition to his character design when the first game was produced over half a decade ago. But as Naughty Dog has somewhat abandoned the Uncharted series, it seems as though they had to bring a piece of it to their latest franchise.
We probably can't refer to it has a half-tuck, but more of a "reverse quarter-tuck", and we can't wait to find more little tidbits whenever the game releases.
