For the 360 version, we use the Right Trigger button for firing weapons. Pressing this halfway brings out your weapon into zoom view and prepares it for firing, and pressing it down fires the weapon. I found this very useful for waiting for enemies to pop out.
As I understand it, the PS3 controller uses the R2 for firing, but Im guessing this doesnt allow you to press it halfway or am I wrong here? How do you do free aim and zoom view without firing?
