Apparently, via [url=http://puu.sh/1bwFw]Twitter[/url], Marcus Lehto has left Bungie after initially being brought back to work on a top-secret project that still remains a mystery, with [url=http://puu.sh/1bwJb]no intention[/url] of returning.
Super sad news, however it leaves a variety of questions unanswered: Is the project finished? Did the project get abandoned? Did disagreements between him and Bungie open the door to his absence? Either way, good luck to him in the future, and I can't wait to see what the future holds for his work.
Personally, I heard he partnered up with CliffyB. Not really, but that would be awesome.
