I had never really fully explored Batman's combat before, I tended to rely on standard attack/counter, and hardly ever used combos.
Now I can pull off everything without thinking, the only one I have trouble with is blade take-down every now and then. For a while I couldn't blade dodge at all, when I realised all you need to do is hold down back and counter I almost cried.
Playing on Hard, and at first I thought the game was incredibly unfair with the amount of special enemies it throws into the mix, but now I have the move set down it feels perfect. I love the EX type versions of your quick gadgets, especially.
I know some of you will be playing how I used to, maybe overwhelmed with the vast amount of options. I absolutely recommend taking the time to lean every move, maybe even going as far as to repeat specific encounters that give you opportunity to practice. The combat takes on a completely different feel once you can access everything on reflex.
