But I was watching a let's play of AA today that reminded me I should have bataranged those guys in the face while they were charging. I don't think they ever mention the trick in AO. I was like, "oh yeah!"
I gave up on trying that after I tried Bataranging Killer Croc right at the beginning of the game whilst he charged me and it had no effect. Same with Enforcers (was that their names? The huge dudes, first encountered in
).
I found one of the reasons for me sucking at combat recently last night. I got fed up with not being able to progress in my Datapack Hunt due to the electricity in the Hotel, so started NG+, and I've found that if I'm in the middle of a beatdown and the camera shifts, even a little bit, Batman re-centers himself and as such just simply stops, even mid-beatdown. It also happens with some other moves where as soon as the camera moves Batman loses his target, so either punches empty space or just simply stops dead as if you've let go of all controls.
In City, if you were doing a beatdown, you'd be locked. If a thug swings at you and you counter, you'll end up continuing you're beatdown straight after. In Origins, you have to actively aim Batman back at the guy you was beating down.
Hope this helps anyone having trouble like I have. Admittedly, I'm still suffering, but certainly not as much as I was during my first playthrough. If you know what to look out for, you have a chance of compensating.
