First, you will be attacked by clay demons. Fight them off just the same as the ones you did before. After you've defeated them, Al Ghul will come up in giant form out of the sand. You want to shoot quick electrical charge shots at him but they have to get beyond his rotating wall of soldiers. This is easier than it seems. Just keep shooting and it'll slip through. The only real challenge is doing this will dodging his other attacks. Just dodge whenever you see any kind of attack coming. They travel fast and you can't afford to hesitate. Once this is done, you'll be attacked and need to keep hitting the counter button.
You'll get some conversation at this point but then you will be attacked. By a lot of enemies. Hammer on the counter button until all of the indicators are gone. This will give you an awesome combo counter to start with and then you can just run around bashing on all of the enemies. If you don't kill all of the enemies fast enough, the beginning of this sequence where you have to counter multiple attackers will happen again with whatever remaining enemies there are. Once you've cleared them all, Ra's Al Ghul will appear in his giant form again. Destroy this form just as you did before and he will attack you again. Hammer on the counter button again.
After you finish the fight, you will have to use the reverse Baterang on him. Hold the aim button and then use RB/R1 to lock on. Release the button to throw the baterang to finish up here.
