... is the name of the achievement you get when you beat all four campaigns on expert. Me and a few others have been taking a break from VS to work on this over the last week or two.
Last night was particularly awesome. After getting repeatedly, frustratingly destroyed on Blood Harvest for the last few nights, I switched it up and started a lobby for Dead Air. (heh, the night before, we beat both tanks at the end, and then as we turned the corner, there was the third tank STANDING ON THE RAMP TO THE APC!!! #$%@!)
Anyway, Fallen, Namebot, and Helmetless Helgast joined up, and we started without drama (i.e. didn't spend the typical 45 minutes in the lobby trying to get a freakin server

). When we left the greenhouse at the start of lvl1, we handled a horde, but then namebot and fallen got disconnected by steam. After they reconnected, we restarted to make sure they'd get credit for beating the campaign, if we were lucky enough to do so.
It turns out that would be our only restart of the night! We had incredible teamwork the whole night... the kind that "just happens". Isn't it funny how sometimes you just gel and other times you just can't do anything right? There were a couple of close calls, where we had three guys incap'd, but we never had all four die. At the end of it, all four of us ended up getting our "expert dead-air badge"! What's even more stunning was that we got it on the first attempt at the finale!
(The hill behind the plane is where to be - long sight lines makes it easy to kill the horde, and then you've got a big open space in front/right of the plane to deal with the tanks. Plus when you beat the second tank, you're right there at the plane.)
Anyway, I had a crappy day yesterday (didn't get a job I'd interviewed for and expected to get), and this was the perfect attitude-adjuster at the end of the night. Thanks for the awesome teamwork guys
