Half-Life, Portal co-writer Chet Faliszek left Valve a month ago

One of Valve‘s most visible public faces has moved on from the company.

Chet Faliszek, writer on games like the Half-Life episodes and Portal, left Valve more than a month ago. For over a decade, Faliszek worked at Valve as one of its primary storytellers. Most recently, however, he has worked as Valve’s virtual reality ambassador. Faliszek would travel to events like the Game Developers Conference, Slush Play, and more to talk with developers about creating VR games and experiences on top of Valve’s open SteamVR tech. While the company has experimented on VR for years internally, it was Faliszek who turned the company into one of the best communicators on how people could best approach the technology as creators.
