Sadly smart pause, extended ear, night goggles and other elements which imply to FoW, are there because FoW USED to be there, but they cut it out, because "auto-pausing was interrupting game flow every time when new enemy popped on the screen", which is a lousy excuse. It is either poor designing from their part, or just that they ran out of testing time before deadline; which comes in between lines from that thread, so they scrapped it.
They MIGHT be adding it as a patch later on, which is when I MIGHT be buying it. Too bad, I was hyped up and I was going to preorder it until I found that out. FoW is an essential feature to me. Not going to support such dumbing down with my monies.
