Just a little tip for interrupting and countering attacks. You can only do it when the attack just starts coming at you. So with Father Gascoigne you don't want to shoot him while he is winding up the attack, but the second he swings it down at you. The timing is very tight, but once you realize that, it makes it a little less random. Unfortunately not all attacks are interruptable. Which makes the mechanic even harder to figure out.
