I played about an 1.5 hours through the tutorial to get a feel for it. Pretty good so far. I have manged to kill my most veteran squaddie (Thin Man poison attack), but have kept the others alive thus far (course this is only on normal mode).
I recognize that I am only playing the tutorial, but it seems to me the missions thus far appear 'canned' as opposed to entirely random? I hope I shake this feeling when playing a full campaign.
Looks like I will be losing sleep over this title.
