Naughty Dog's hard at work on a new expansion to The Last of Us called Left Behind...but that's not the only thing it's working on.

The developer also revealed a small but significant teaser trailer for its next game in the Uncharted franchise. There's an interesting twist, though. Instead of focusing directly on Nathan Drake, this entry in the series has a much more dramatic turn, where a darker voiced character (possibly the villain) speaks about being imprisoned for 15 years, and vows to seek revenge on those who wronged him.

No other information was given about the game, but we're sure to see more in the months ahead. In the meantime, check out the teaser trailer below!
