Pretty good story here: http://forums.2kgames.com/showthread.php?150771-That-s-XCOM-That-s-bull-****
Including, amongst other things, this wondrous paragraph:
"More then half of the enemy troops have been killed, I'd lost only 1 assault to a friggin crysalid(sp) that nommed on him, and everyone else was in pretty decent shape. Then... a floater, barely in view range, took the luckiest God damn shot of all time at my 2nd assault IN HIGH COVER NO LESS and hit him, full damage roll, dead. This caused my rookie to panic. And oh man did he panic, he shot and critically injured my Heavy. This, in turn, caused my Sniper to panic, he turned and fired at my Support, who was sitting a block away (a floater jump jetted early and got a shot off, so I sent the support back to heal him), missed, but hit the... umm... it was either a fuel pump or a car... or both sitting behind him, exploded, Support and Sniper dead. So here I am... 4 men down, 1 bleeding out, and a panicked rookie. Hint: IT DIDN'T END WELL FOR ME."
