Before working at Lucas Arts, Clint Hocking's more notable role in the game industry is leading the development for games like Far Cry 2 and the original Splinter Cell at Ubisoft. A couple of weeks ago, he had announced in a blog post that he had left his post at Lucas Arts, where he spent his time working on unannounced projects, to move on to something new.
Today, Hocking revealed in a pic tweet that he had arrived at Valve HQ with his son.
It's unclear what role he'll take on at Valve. There's still work to be done on Team Fortress 2, Dota 2, and Counter-Strike: GO. But maybe his time will be spent working on the more secret of projects like, uhm, Ricochet 2. Stay tuned as always.
