I just managed to complete hardcore extinction with two randoms on what was my second proper attempt.
At the end it was weird though. I came extremely close to downing but made it to the chopper, it shows my character on the chopper but one person was down yet it came up with "everyone survived."
By the way are sentries a bad thing to use in hardcore? None of my two teammates places a single one down that game. I had to keep vultures on the battlefield. I checked and my teammates had 4000 - 6000 cash very often.
