how about a free look like used in most racing games?hold bumper and flip the right stick left or right for a quick look without needing to turn your whole body.

im obviously assuming the controls will basically be like GRAW's.

i think i see what you're talking about....at about 1:20?

i was thinking of just a glance(turning your head) but thats very cool.

Ya you saw the part where the support gunner was pulling security for his squad as they moved.
