Before I critique, I would like to preface that I love the overall direction of the game and the passion being put into the project. I have faith that it'll be great and it'll stay true to what made the original so amazing.
So I've seen the magical demo many magical times. Did any of you find that it wasn't nearly as scary as it should be? I remember playing the old XCOM and being constantly scared. The map was super dark and contrasted (night missions). I would crap my pantaloons when an alien was just around the corner and I didn't reveal them until just turned that corner. My soldier was, all of a sudden, face to face with a Muton with the barrel of his rifle pointed at his/her soft human dome.
I understand that it was a flashy demo made to quickly convey the gameplay mechanics. So I'm REALLY hoping that fog of war is it was in the original.
That's where TUs were important in peeking around corners and getting a good visual on the scenario before executing the next plan. It seems that a lot of line of sight was streamlined and the soldiers do a lot of the visual checks. As if their field is vision much larger than it should be.
