Great game, finished already (I am in AUS so it was unlocked about 14 hours ago).
The AI however, is quite broken, the stealth section is quite easy to the point that you can turn off the area light and stand 4 feet away in front of them with no detection.
Shooting feels much more refined.
Haha true the shooting seems alot better, but i have not really tried stealth in dark areas yet. I was born to shoot stuff i guess.
