After Amy Hennig left Naughty Dog and her role as director of the upcoming Uncharted 4: A Thief’s End earlier this year, The Last of Us co-directors Bruce Straley and Neil Druckmann stepped in to lead the Uncharted series’ debut on PlayStation 4. Set in a grim, post-apocalyptic world, The Last of Us is of course a much darker game than Nathan Drake’s thrilling but largely light-hearted adventures.

Though the first trailer for Uncharted 4: A Thief’s End was darker than usual both visually and in tone, Naughty Dog says that The Last of Us’ grittier mood won’t bleed into Drake’s next adventure.

“Uncharted is a completely different franchise, and appeals to its audience for completely different reasons,” Naughty Dog’s co-president Evan Wells told Eurogamer in an interview. “I don’t think The Last of Us marks a new direction in tone that all of our future games are going to take on. We’d alienate a lot of our Uncharted fans. We want to keep it a light-hearted romp. I think from a technical standpoint we’ve learnt some things from the Last of Us that will feed into Uncharted – in fact it strengthens our desire to keep them distinct.”

Uncharted 4: A Thief’s End is scheduled to be released on the PS4 at some point in 2015. Sony Pictures also recently announced that a movie based on the Uncharted game series will make its debut in theaters on June 10, 2016.
