Portal 2 writer Jay Pinkerton has left Valve

Another longstanding member of Valve’s writing team has left the studio, with Portal 2 scribe Jay Pinkerton announcing his departure over on Facebook.

Pinkerton, who worked at Valve for almost a decade, didn’t offer any indication as to why he left the studio, but the recent number of high-profile departures might suggest there’s been a change in the company’s creative direction.

The first to go was Half-Life writer Marc Laidlaw, who stepped away last January to take a break from “the chaos of game production” and focus on his own projects.
