I'm pretty damn sure that I've just gone through something that makes Chrysalids, Mutons and Leader Sectoids pale in comparison. I was on top of the world, I managed to rescue a VIP with rookies, starting to make major leaps in my base outline, get quite a few satellites in the air to increase my income, research new armor types, build some shivs and then...it all went wrong. I started a terror mission and managed to kill the first Chrysalid, but when want to kill a civilian, it glitched out and I had to restart the game...that's when I realized Enemy Unknown doesn't have an auto-save system and all of the stuff I mentioned eariler just got flushed down the toilet...FUUUUUUUUUUUUUUUUCK!
