Brad Muir of Double Fine fame recently announced that he’ll be leaving the company this coming Friday.

So where is he ending up? He posted over on his Twitter that he will soon be joining Valve this December.

For those unaware of his work, he played a pivotal role in the companies history, from being a programmer for Psychonauts to lead designer of Brutal Legends, to becoming project lead for Iron Brigade, Brazen and most recently Massive Chalice.

It’s unknown what his next project will be with Valve, but hopefully we’ll learn soon enough.
