Well, I bought it during the last Steam sale. Lots of fun so far. At times very scary. I'm still figuring things out, but I selected the tutorial and normal difficulty and I'm basically using this as a trial run-through. I almost got depressed during the mission with the downed spacecraft because I lost two people in a single turn. Then, a third person in my mission began to have a panic attack and became useless. I literally won it with my last person on a lucky shot. Then the next mission, I lost somebody else in an ambush.
But I've gotten better. I haven't lost a single person since that point (last round, someone was bleeding out, though, and I won a turn before he died). I still don't quite get cover the way I should and I definitely have trouble getting the situations where aliens can shoot at you when you run from one cover to another, but I think I'll eventually get the kinks out.
