Erik Wolpaw has left Valve

Erik Wolpaw has worked as a writer on some pretty big games, including not only Half-Life and Portal, but also the great zombie shooter Left 4 Dead. He'll surely be missed, then, as former Valve man Marc Laidlaw confirmed on Twitter that Wolpaw is leaving Valve.

"@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," Laidlaw tweeted.

The news is also confirmed via Facebook, where Erik Wolpaw's profile shows that he has parted ways with Valve.
