Naughty Dog reveals just how much the extra power of the PlayStation 4 helped make Uncharted 4: A Thief's End the biggest and most detailed game in the franchise.

There's no doubt that Uncharted 4: A Thief's End is going to not only be the most visually impressive Uncharted game to date, but thanks to the power of the PlayStation 4, it may also be one of the best looking console games available. In a new developer diary, fans are able to get an inside look at how the developers at Naught Dog were able to utilize that additional console power, and how it was able to make Uncharted 4 the biggest and most content-packed game yet in the franchise.

Titled Pushing Technical Boundaries, the team at Naughty Dog reveal that Uncharted 4 is delivering 10 times the explorable space than has been seen in the previous three games, allowing players to complete objectives in a variety of different ways. Obviously, this created a variety of challenges for the Naughty Dog developers to overcome, specifically by finding a way to keep the story just as intense as past games even though players have more choice and freedom while playing through levels.

The added hardware power of the PlayStation 4 also allowed developers to push the engine further by creating levels that were denser and featured much more detail than had been previously seen. In addition, the added hardware and performance enables the use of in-game cutscenes in Uncharted 4, so instead of cutting away to a loading or black screen, the experience is seamless when transitioning from gameplay to a cutscene.

Finally, the video also reveals that, unlike the first three games, Uncharted 4 actors Nolan North, Emily Rose, and Troy Baker all had their facial expressions captured in addition to their body movements. This was done to make the characters seem more life like and believable and thus to help keep player immersion in Drake’s world.

After suffering through multiple delays since its original announcement, development has finally wrapped up on Uncharted 4: A Thief's End as Naughty Dog announced earlier this week that the game has recently gone gold. Any fears that fans may have had that the game would once again miss its announced launch by another week or two can be put to rest as the disks are now being manufactured in advance of its quickly approaching release date.
