In the original Crysis you had a leaning using the E and Q keys, in Crysis 2 this was replaced with a cover system by holding the right mouse button.

In Crysis 3 however none of these things are present, what gives?

It's not that big of a deal I guess but I really liked how your character lifted his weapon up against walls and that you were able to peek around corners and from cover spots.

To be honest i didn't even realize that they removed it considering i barely used it in Crysis 1 and 2 . In crysis 1 it seemed fine but in crysis 2 it seemed to always get in the way of aiming before you were about to pop out and shoot someone. Im glad that it was taken out.

but in crysis 2 it seemed to always get in the way of aiming before you were about to pop out and shoot someone.

I personally didn't have problems with it (neither in Far Cry 3 which uses that very same system) but if many felt like you did about this I guess I could see why it was taken out

Maybe because it was useless and out dated?

Im also glad its out, more usefull binds FTW.
