While speaking yesterday at a Metrocon panel, Nolan North, the voice actor behind the hero of the Uncharted series, Nathan Drake, opened up about changes the forth installment went through when the series creator and creative director, Amy Hennig, departed in early 2014.

Speaking about the transition following her departure and the stepping in of Neil Drukman and Bruce Straley, the pair who led development for The Last of Us, “We had shot 8 months of her story and it was all thrown away. The Last of Us guys came in and you have to understand, new producers, new people, they want to do it. I don’t know what happened exactly. Amy is still a very, very dear friend of mine and she’s brilliant, but The Last of Us guys were the next team there, so they took over and just wanted their own flavor. They got rid of some of the other people that were involved and just redid their thing.”

As far as how Uncharted 4 now compares to the game it would have been under Hennig, North went on to say, the tone was certainly going to be different, “It had to be… A Robert Ludlum novel is not going to be the same as Stephen King. They’re different styles. But it’s true to the story… It’s going to be along the lines of the same story,” he continued. “I don’t know how it’ll affect the whole thing and to be honest with you I’m just as curious as everyone to see what the final product will look like.”

Uncharted 4 recently had quite the showing at E3, and, since leaving Naughty Dog, Hennig is hard at work on a still undisclosed Star Wars project with Dead Space developer, Visceral Games. To hear the rest of what Nolan North has to say, you can find the full panel here.
