Walt Williams, a writer at 2K Games whose credits include Spec Ops: The Line, has left the developer, according to two tweets from his account on Friday.
Williams, who had been lead narrative designer on Spec Ops: The Line, said he would remain in the video games industry but would be working in the background.
"Working at 2K has been one of the most trying, difficult, and mind-blowingly wonderful experiences of my life." Williams said. "I'm not leaving games, but I am leaving AAA. Not b/c I don't love it — I totally do. I just want to try something new."
He had spent nine years at 2K Games. In 2012's Spec Ops: The Line, Williams sought to create a story — evocative of Joseph Conrad's Heart of Darkness — in which the overwhelming forces of nature would push players into making decisions they never would consider otherwise.
In addition to his role with Spec Ops: The Line, Williams also is listed as a senior writer and designer working with Turtle Rock's upcoming Evolve and Firaxis' forthcoming Civilization: Beyond Earth.
