Not as good as the demo portrayed.
Ok I loved the demo. it was scary, looked good and had some cool guns. Basically what you see in the demo is pretty much what you get all through the game. That's actually a bad thing. Nothing shocked me. Nothing made me scared. I thought this was supposed to be horror? More like shoot as many soldiers as possible which let's face it, using slow-mo makes it easy. I played this through on hard and completed it in 3 days. I couldn't believe it had ended. It's not like I was on it all day either. Online is a joke. There is a serious amount of lag so you see players shooting thin air trying to hit you even though you are standing next to them. It's a great game but a huge disappointment in my opinion. I can imagine some sort of patch to fix that will come out.
Lots of gore
Not remotely scary
Not even challenging
