Watch new Uncharted 4 mini-documentary here

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 learn about the game's themes and storylines. The 7-minute video, titled "Growing Up With Drake," is available below.

Co-director Neil Druckmann also talks about how Nathan Drake's own journey -- 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

It's been a long time coming for Uncharted 4. The PS4-exclusive was first scheduled to launch in 2015, but was later moved to March 2016 and then again to April 2016 before its latest delay to May 2016.

Uncharted 4 is the final entry in the series that Naughty Dog plans to develop and the last one to feature Nathan Drake in the lead role. However, the series may live on with another developer.
