Sure. I'd be up for that.
We can stop the constant microphone broadcasting which at first seems to be a left over from the 360 version.
However, this isn't entirely true. Seems the game just uses our Steam voice setings; which for many of us who have never bothered to fiddle around with them, default on automatcially transmit.
While in game, open your Steam overlay; Settings; Voice; and switch to use push to talk!
