The script of "breath" adds another bit of reality. A lot of players in the game noticed that the camera did not falter, and when aiming, the sight is straight without hesitation, shooting with it too accurate, but not in real life, because if you breathe a sight ranges and so didn't exactly shoot. In the game, it turns out that Karl seemed not a man, but a robot that does not breathe, but this script corrects this error! Now Karl breathes and accordingly will be small fluctuations of the body and the camera would be a bit unsteady, so strongly does not hurt. Watch the video closely and you will see for yourself.
