Watch new Uncharted 4 mini-documentary here - CNET

Sony has released the next "Making Of" video for Uncharted 4: A Thief's End. This one focuses on how the actual game developers--many of whom were in their 20s when the series started--grew up alongside Nathan Drake and other Uncharted characters. It's another really cool behind-the-scenes video, and it talks about a lot more than that, as we also lea about the game's themes and storylines. The seven-minute video, titled "Growing Up With Drake," is available below.

Co-director Neil Druckmann also talks about how Nathan Drake's own jouey--making sacrifices to achieve greatness--is not unlike how he and other studio members feel about making the Uncharted games.

"As a game developer, this is hard work," Druckmann said. "People think you're here playing games all the time and sure, that happens every once in a while, but for the most part, this is very hard, grueling work. A lot of times it's long hours and you make personal sacrifices."

This is the second of five planned episodes in the series. The first one was called "The Evolution of a Franchise" and you can watch it here. Here are the names of the upcoming four episodes:

• The Making of Uncharted 4: A Thief's End: Pushing Technical Boundaries Part 1
• The Making of Uncharted 4: A Thief's End: Pushing Technical Boundaries Part 2
• The Making of Uncharted 4: A Thief's End: In the End
