Chet Faliszek has left Valve after devoting 12 years to the company.
Speaking with GI.biz, Faliszek confirmed his departure, stressing there were no “hard feelings” with the company – only that it was time for something new.
“[It was]Nothing exciting or drama filled,” he told GI.biz. “I worked there 12 years, shipped a bunch of great games and some amazing hardware and wanted to change things up.
“There’s no news on what’s next etc, I will let you know when that happens.”
Faliszek co-wrote storylines for the Half-Life series and Portal alongside fellow writers Erik Wolpaw and Marc Laidlaw, who both left Valve previous to Faliszek’s departure.
He also wrote the story for both Left 4 Dead and Left for Dead 2, Counter-Strike: Global Offensive and was a writer for Dota 2 alongside Marc Laidlaw and Ted Kosmatka.
In the past few years, Faliszek took on the role of developer relations boss for Valve’s Vive VR. He worked as a liaison for developers who wished to publish titles on the firm’s VR tech.
