The way the game approaches gun play is especially inspired. Taking cues from Metal Gear Solid 4, Peacewalker seems to have completely ditched the awkward first person shooting that Portable Ops relied on. Rather, holding the left shoulder button with a gun equipped has you shooting over the shoulder. The face buttons are then used to aim with the right shoulder button being the trigger. You can even move around while aiming this way using the analog nub, which is just a wonderful addition.
