Hey:) I have already checked your ME3 walkthrough. Batman AC is not a hard game but there are stuff I have forgotten since I last played Batman AA.
Batman Arkham City Walkthrough
Holy toledo, Batman! Our Batman Arkham City Walkthrough will provide info about gadgets, a storyline guide, and locations of secrets.
Boss Beat Down
The hardest situations in Arkham City are the Storyline boss fights. From the super natural zombie Solomon Grundy to the cold hearted Mr. Freeze, you'll need to change your tactics and gadget use for the specific foe you're facing.
The Penguin and Solomon Grundy
The Penguin isn't one to get his flippers dirty--that's work for the hired mooks. And there's no better lackey than giant zombie gangster Solomon Grundy. This brute is far too tough to take on and even worse, he's healed by electric shocks. But his lifeblood is also his weakness. Lay down some of your bat mine and detonate each of the generators. This will leave Grundy open to a pounding.

The Penguin has back up generators, so you'll need to repeat this process a few times. Each time the machines are rebooted, Grundy will be a little more deadly. However, with some added quick dodging, your strategy should remain the same. If a generator lid shuts, you can still lay down an explosive to detonate once it reopens. Once Grundy is slain, the Penguin will attempt to take you on. He's easy to avoid and it only takes a quick combo to send him back to the Arctic.
Ra's al Ghul
The strange realm of Ra's al Ghul will distort Batman's senses, flashing between the dream world and the struggle in reality. You'll first need to win a bout with a group of sand assassins. Their blades should be avoided or dodged before being countered with a strong combo. Ra's will next make an appearance in the center of the map; dodge his giant swords and ninja stars, before shocking him with the REC. Quick dodging is key here, as being staggered by Ra's attacks will leave you open to another hit.

After a direct assault, it's back to the gaggle of sand ninjas. Tap the counter attack for each of them, or you'll be suffering from more than nicks and scratches. Ra's will teleport in for a rush down attack, so be extra swift about leaping out of harms way.

Ra's will once again take center stage, but with even more protection. You'll now need to be extra quick and accurate with the REC to gun down the immortal. After another counter and beat down, use your reverse batarang to send Ra's to his knees.
Mr. Freeze
Victor Fries is far too strong to take out in a direct fight. Instead, you must prove to be a master of stealth in order to cool down the good doctor. Freeze will catch on to your strategy and block off locations, making each of these sneak attacks a one time deal. First hide within the grates and pop out with and underground takedown. Second, you can also take the high route and bounce on Freeze from the upper banisters.
You can also use the standard slow and sneaky back attack; destroying one of the sculptors of Nora is a guaranteed way of distracting Freeze. However, after executing this maneuver Mr. Freeze will deploy icy shards from his backside, making him unapproachable.

Freeze is also susceptible to electric shocks and there are two excellent places to add some sparks. First wait for freeze to stand next to the generator and fire out a REC blast. A great spot to wait across the room out of view. The second electric zone is in the pool of water in the center. This time you'll need to lure the villain out and tap the button on the side.

After five sneaky beat downs, Mr. Freeze will come to his senses and will even reward to you with a parting gift: the Freeze Blast grenade.
Joker, Mr. Hammer and Titan
The fight with the Joker is stacked against you. The villain is not only a tough fighter but has help from an army of goons, a one armed mercenary, and a Titan mutant. Thinning the herd quickly is the key to surviving the fight, and thankfully you can manipulate the unique foes.

Abramovici will twirl when hit by the REC. This doesn't hurt him, but the spin can damage any smaller foe standing around him. You'll need to be fast with your shots, as not only do the clowns come in swarms, you'll have to be mindful of the funhouse cars plowing through the arena.

What really helps is riding the Titan. First clear enough space around your target and follow up with an Ultra stun. Pounce on his back and gallop through the opposition.

The Joker will often grab boxes and knives, making him both a nuisance and a threat as you attempt deal with his two largest lackeys. Put the clown Prince on ice with a Freeze blast to lower your chance of being distracted. After the help is gone, end your session by introducing Joker to your designer bat boots.
Clayface
Grab some popcorn and soda, as the final reel is about to play. Actor extraordinaire Clayface will do is best to smash and slice you, but with quick footwork and evasion his blows are easily dodged. Your Freeze Blast grenades are the key to dealing damage. Once Clayface is downed, brandish Ra's sword and premiere the final cut.

But the Joker has one last laugh in the Lazarus pit. Chop down the clay constructs and Clayface will spring from his puddle. Toss a freeze grenade to make the blob frosty. Each time you chill out Clayface you'll need to destroy an even larger wave of goo soldiers. Breach through the crowd and toss one last ice bomb to finish Arkham City.
