Soon many will be able to experience Uncharted 4: A Thief's End in shiny 4K on PlayStation 4 Pro, and this is the perfect chance to go back to the drawing board (quite literally) to check out the concept part that gave birth to the game, thanks for quite a few new sketches recently shared by Concept Artist Eytan Zana on his ArtStation page.

Zana has worked at Naughty Dog since 2010, taking part in the creation of Uncharted 3, The Last of Us, and all the way through Uncharted 4. You can check out his beautiful art just below.

Keep in mind that some of the images could be considered spoiler-ish, even if they're presented with no context.

While not as recent, many other Concept Artists from Naughty Dog posted their own sketches and artwork over the past few months, so we're taking this chance to celebrate them all.
