I’m using 3D (also called Force) Touch to shoot. So I can use my right thumb to look around but then when I apply a little more pressure I shoot; you can also hold your thumb down with more pressure to shoot full auto. There’s still the fire button on the left side of the screen when you’re using 3D Touch though so you can stand still and get real precise when trying to snipe. It’s really fluid and makes shooting while moving considerably easier. I’m really hyped for the North American release!!
