Batman: Arkham City is an upcoming sequel to Batman: Arkham Asylum.
A year after the chaotic events of Batman: Arkham Asylum, both the Elizabeth Arkham Asylum for the Criminally Insane and Blackgate Prison remain gutted, the former in a massive breakout launched by the inmates and the latter due to a mysterious fire. The administrator of Arkham, mayoral candidate Quincy Sharp, soon takes advantage of the Batman's defeat of the Joker at Arkham and claims the credit himself for bringing the asylum back under control. This is partially to salvage his image, in tatters after the single worst asylum riot took place at a crucial time when Sharp was trying to convince the people of Gotham City to vote for him.
This is successful, and Sharp is elected mayor of Gotham. His first act is to announce ruined Arkham Asylum and Blackgate Prison both unfit to house criminals. He then undertakes a bold new project: To move all the former inmates of incarceration at both places into a walled-off urban district, Arkham City. This will be a city only for villains, and is made up of Gotham City's most notorious slums, including Crime Alley. To guard the perimeter of Arkham City the mayor does away with Arkham Asylum's old security force and replaces them with professional mercenaries from a private military organization, TYGER. Once all the criminals are trapped inside the prison city, they are told they may do as they please, but there is only one rule: Do not escape. This is supported by the TYGER mercenary forces, who enforce this policy through the liberal use of their firearms on any escaping denizens of Arkham City. Since the entire population of Arkham is made up of criminals running wild on the streets, Sharp secretly hopes they will destroy each other inside walled confinement instead of committing crimes in Gotham.
With the criminals free to do whatever they want short of escaping, bloody turf wars erupt as various supervillains carve up Arkham City among themselves. A mysterious figure named Dr. Hugo Strange, an Arkham psychiatrist, is placed at the helm of the project by Sharp, but little is known about his objectives or his shadowy past, and rumors soon run rampant that he is up to horrible things behind Arkham City's walls. Those who try and find out too much about Arkham or Strange one by one mysteriously vanish by night, and it is implied most end up inside the city themselves, to be torn apart by the inmates. Batman, wary of Sharp and even more so of Strange, monitors Arkham City for several months, believing that the entire thing has been a ticking time bomb waiting to explode.
His pretext to infiltrate the place himself comes when Catwoman, who has no gang and is working as a freelancer in Arkham City, is captured by Two-Face and his henchmen. Two-Face, a new inmate, is short on men and weapons and cannot afford the costly gang battles he is already embroiled in. In order to help achieve dominance and eliminate a potential rival, the villain announces he will publicly execute Catwoman. By doing so he also hopes that this will win him some support among the criminal populance. Given their past, Batman has no choice but to enter Arkham to save her and uncover what's really going on. With a brand-new bag of tricks, the Dark Knight might just survive the night locked up in an anarchic zone with all of the city's worst freaks and madmen.

- Catwoman - Catwoman is controlled differently than Batman. She has her own story, (Roughly 10% of the game) and her own combat moves (uses her whip, bolo, and unrevealed third item). Instead of gliding, she uses her whip + jumping and climbing through the environment. She has her own version of detective mode, which is known as thief mode. Theif mode highlights objects of value. Along with her whip and the bola, Catwoman uses a Caltrop in combat. She can also crawl along ceilings, climb building, etc with her claws. While some of her missions are optional, she will have to be used on occasion seeing how her story is intertwined with Batman's.
- Tim Drake/Robin- Playable only as a pre-order bonus from Best Buy or as DLC. Robin will not impact the story, but he will be avalaible on all of the challenge maps, and he has his own exclusive challenge map featuring Black Mask.

Arkham City is five times bigger then Arkham Asylum. Because of that, there is a less constrictive feel to the game, and a lot more movement options for Batman has been given.
Gliding has been given a major overhaul in Arkham City, in Asylum, the player was limited to a very simple glide mechanic that allowed the player to slow descent, allowing them to cover more ground whilst airborne, and perform turns in the air. In Arkham City, Batman swoops across the rooftops, and can execute two new moves that allow him to maintain his glide indefinitely.thumb|405px|right
The first move, the Dive Boost, is very similar to the Dive Bomb, where Batman will pull his cape in and hurtle towards the ground, opening his cape at the last second, and using the newfound boost to make him soar back upwards into the sky.
The second move is the Grapple Boost. Batman can fire the grappling gun from the first game in mid-glide, and use the line to pull himself through the city.
If Batman is feeling tired, or perhaps wants to travel around in a stealthier fashion, he can now use his Grappel Gun to zip up to a helicopter and hang off it, as well as a sneaky way to travel around Arkham City, Batman can also use this elevated position to plan out his next plan of attack, before dropping into the frey.
The Line Launcher from Arkham Asylum makes a return, but the gadget has been heavily upgraded since the last time we saw it, Batman is still able to use it to quickly get from one place to another, though in Arkham City it will open up a whole new range of movement and strategic possibilities. Rocksteady have confirmed that the player is able to fire and travel along the rope line, in the same manner as which they did in Asylum, however this time around the player can swivel the camera around Batman, and at any point during the Line Launcher transportation, execute a flip into the air, following up with a quick second shot from the Line Launcher. Batman can perform this move with 360 degrees of flexibility, and similar to the Grapple Boost, this tactic can be repeated to keep Batman off the ground indefinitely. When travelling down the line, the player can press a button that will slow down time, allowing for easier line launcher shots. Batman can also anchor his line between any two points, and then flip up on to it, balancing in place. Batman can move the distance of line, using his position to plan an attack. More aggressive players can then choose a target, and swing down using the line, slamming their chosen enemy into the ground.
Changes have been made to the combat system as well. Batman can now pull off double and even triple takedowns. He can also counter thrown objects by catching them and throwing back, and he can flip over an enemy and attack another in a fluid movement.
Batman also has a few new moves in the game.
Beatdown- performed by pressing X and B (360) or Square and Circle (PS3) that unleashes a flurry of punches and kicks on his opponent. A demonstrated use of this is to takedown armoured enemies.
Batman also has combat abilties added in addition to the new movement abilities.He can pull off a new move called Dive Bomb, Batman can drop from either a great height, or execute the manoeuvre mid glide, plummeting towards the ground to either reach his destination quicker, or make a dramatic entrance to a fight. Rocksteady have confirmed that thugs will jump back in fear, and are not forced back by a form of shockwave generated by Batman’s impact.
As well as the Glide kick, Batman can perform and a throat slam by firing his grapple gun at an enemy whilst gliding, which fire Batman into his opponent, slamming them into the ground.
Batman will use the environment against his enemies, thanks to context sensitive animations Batman will slam thugs heads against walls if he is close enough.
You can employ Explosive Gel into combat, executing a quick flip, Batman can spray either the ground or an enemy, and detonate the gel at his leisure for explosive effect.
Batman's attacks can knock thugs into each other, potentially taking multiple enemies out at the same time.
The Silent Predator missions have returned. In Arkham Asylum Batman could perform many exotic environment based takedowns (Such as the Corner Takedown or Ledge Takedown) Arkham City is set to increase the variety of these takedowns. Similar to combat, we've excluded certain gadgets like the Ultra Sonic Emitter, which can summon bats to aid you, and will go into the stealthier aspects of the Dark Knight at a later date.
Batman can burst through thin walls to grab an enemy and choke him unconscious, in gameplay terms it's a combination of Asylum's explosive gel and a standard silent takedown.
Batman can now perform double silent takedowns, as well as hanging takedowns. Batman also has a new smokebomb gadget, small smoke grenade that distracts the enemy and obscures Batman from view just long enough for the Dark Knight to make his escape. To use the smoke bomb, the player must hit the Y or Triangle button when he is spotted by enemies.
Batman can also sabotage his enemies weapons, so that when enemies spot and attempt to fire at him, the guns will misfire.
In Arkham City Detective Vision has been given an overhaul, in Arkham Asylum DV made the environment transparent and enemies illuminated. To combat a frequent problem of players simply leaving the mode on, and severally reducing the visual experience of the game, in Arkham City DV will highlight enemies and interactive objects in more detail and at greater range than before, though the environment will be very hard to distinguish, forcing players to use DV sparsely if they want to navigate effectively.
Detective vision will highlight all characters, weapons and interactive objects in the area.
Also returns from Arkham Asylum, the gel can be deployed in combat, either against the environment, or onto an attacker.
Can pull thugs towards Batman, who are then promptly finished off with a brutal takedown. Can also be used to grab items like Riddler Trophies.
An improved version to it's predecessors' in Arkham Asylum, able to fire multiple lines, hold a static line across two points, and be utilised for a special drop-kick, for more details please refer to the in depth description in the Movement section.
Very little is known about Arkham City's standard Batarang, they will likely remain the same as Arkham Asylums.
Another returnee from Arkham Asylum, this new RC Batarang has new features that enable it to perform a 180 degree turn, boost through the air and brake. Previews have also stated the RC 'rang is capable of carrying an electrical charge, to solve a Riddler riddle.thumb|right|382px
Batman's remote hacking device allows him to decode encrypted data sticks and listen in on radio broadcasts throughout Arkham City, such as GCPD comms, which may alert him to crimes.
A new addition to Batman's arsenal, allowing him to make a hasty escape if discovered. For more information, please read our Silent Predator section.
A tool that allows players to attract a swarm of bats to a designated area; first reported in the 2009 issue of GameInformer. Rocksteady Community manager Sarah Wellock later issued this statement: "Games are in a constant state of flux and this demo was shown July last year to press. Naturally a lot has changed since then and I sadly can't comment on the status of that feature...."
