Shaun Escayg, the creative director of Uncharted: The Lost Legacy, has left Naughty Dog after seven years, the developer announced.

“Seven years ago I joined the talented team at Naughty Dog on a project still in its infancy, The Last Of Us,” Escayg said in a tweet. “Well, the rest is history. Left Behind, Uncharted 4 were fleeting and Uncharted: The Lost Legacy pushed my creative growth even further—I will miss all my dogs.”

In an Instagram post, Escayg shared an image of The Avengers logo with the text “To new adventures—bring it 2018!,” suggesting he is moving to Crystal Dynamics to work on their upcoming The Avengers project.
