Develop has a follow-up to the revelation last June that Turtle Rock Studios, the Left 4 Dead developer acquired by Valve in 2008, was no longer operating separately as Valve South, as they were absorbing its staff into their Washington offices. Now word is the developer has reformed and is hiring staff. They report: "It is not clear what upcoming projects Turtle Rock has in the pipeline, though Michael Booth – a close friend of Valve – is back heading up the studio."
