Wolpaw helped pen Half-Life 2: Episode One and Two, along with co-writers Marc Laidlaw and Chet Faliszek. He also co-wrote Portal with Kim Swift, as well as Portal 2 with Faliszek and Jay Pinkerton.
@Wolpaw left Valve so I can now insult him freely without damaging the company's reputation. He's a comic genius and a true original.

Before Valve, Wolpaw also co-wrote the story for Psychonauts. It's been known for a while that he's helping with Psychonauts 2, so presumably he's gone to work on that full-time.
The news of his departure comes via a post on Erik Wolpaw's Facebook page.
Meanwhile, Valve seem to be focused on Steam and VR titles, with three games in the works.
