Well so far the voice chat is only working sporadically....when it has worked for me I didnt hear anything constructive on it...a bunch of "Woo Hooo"s and a couple "heh heh heh"s. When I tried to offer some tactical comments "One by the water tower.." someone said "The WaterTower? Or the giant fat C#$%?" And a couple giggles....
Soooooooooooo....I turned it off.
