I am just in the starter town near a second group of enemies map position and one of them has a gun. I thought that I can hide behind a wall when he shoots, because he kills me in just two shots... but that is not possible. He literally shoots through walls and kills me no matter where I am with no clear line of sight.
I have no idea how this could get into the released game but this should be fixed ASAP. I hope the rest of the game is more polished.
edit: here is example video on youtube.
