I saw in one of the gameplay videos that you could walk up to a wall and kinda like lean to the side and shoot. was that function removed or is it still implemented? if it is, how do i use it?

you can see it in the controls in menu, i think you hold aim and use dpad on console? i cant remember >.<

its still in. on pc do you use e and q. and on consoles do you use your control-cross (left or right) while using your weapons sights.

Correct, Cold Zero

lmao if you are right!! i went all the way from level 1 to 20 without knowing i could use that! ubber fail

i find it the most awkward thing ever to do, holding LT and then using d-pad while aiming with RS and shooting with RT >.< leaning is a PC thing not a console thing =\ its too awkward for me.

ADS then using the right and left d-pad buttons you will lean either way. Sometinmes you can take down an entire team because they dont register your their.
