Since MO2 is fully first person, it would be good if you can look around with a special key (swivel your head around)
ARMA (and with that DayZ too) for instance has that feature and it allows you to keep better watch on your surrounding when you walk somewhere.
Rather then constantly turning your whole body around to keep watch for someone, just swivel your head to see if someone approaches you.
The feature is already partly implemented when you are on a horse, since the horse moves seperatly from your camera view.
