I thought, enemies cant see you when you are not in their line of sight or behind cover. But on multiple occasions (in first 2 missions!) enemied, who stood in fron of me on the other side of cover, actually detected me while sticked to cover. WTF?! And peaking is basically same as jumping out to the open, they can immidiatelly see you. Then i tried NOT to stick to cover and just stay crouched behind it (not being able to see a damn thing) and you can probably guess how that ended up. And all that on lowest difficulty. What am i missing? For now i play by just sprinting through the room to exit, since gunplay feels like from a flash game, and that is not fun.
