Uncharted 4: A Thief's End director Neil Druckmann revealed a picture of the upcoming game's steelbook cover, which speical editions of the game will carry the game in.
The front features all of the main characters set to grace Nathan Drake's final adventure, while the back showcases something altogether more ominous: the remains of man trapped in a gibbet with a storm in the background.
The artwork may hint at one of the locations in which the game is set. It is unlikely that the skeleton is anything more than that.
Druckmann says that he is currently reviewing potential covers, so there's a good chance that what we see will not be the finished product, as there are other, presumably more spoilery designs that he did not reveal.
Yesterday, Naughty Dog clarified the game's new addition of branching dialog, which it says will not be as crucial to the game as it is in, say, Mass Effect.
Uncharted 4 is scheduled for release in April exclusive to the PS4.
