Did they have to go for the fixed scripting? I had to quit the game a couple of times when the doors wouldn't open because of bugs in the scripting. And I was playing on Ironman, my entire game would have been a waste if we weren't allowed to restart after the volunteer dies. Hope the fix that in a future patch.

Anyways, I get to the last room with the ethereal and it isn't any challenge at all. I just lined up my sniper from outside the room and double tapped the Ethereal. Game over.
