OK, I am in training on FN2 and need to come up with 10 "counters". The problem being I have no idea (a) what a counter is or (b) what controls I need to put together and what motion I need to come up with one.
Hold the Left Trigger and hold a diagonal depending on where the opponent's punch is coming from. For example: A right hand to your head from your opponent you'd hold L Trigger + Up/Left. A left hand to your body would be L Trigger + Down/Right.
So L Trigger + direction of the punch your opponent's intending to throw from your boxer's perspective.
You'll know you did the parry correctly because as soon as you block it your opponent will sort of delay for a second and his guard will be down, allowing you to counter.
