Batman: Arkham City

Batman: Arkham City is a 2011 action-adventure video game developed by Rocksteady Studios and released by Warner Bros. Interactive Entertainment for the PlayStation 3 and Xbox 360 video game consoles, and Microsoft Windows. Based on the DC Comics superhero Batman, it is the sequel to the 2009 video game Batman: Arkham Asylum and the second installment in the Batman: Arkham series. It was released worldwide for consoles, beginning in North America on October 18, 2011, with a Microsoft Windows version following on November 22.

Written by veteran Batman writer Paul Dini with Paul Crocker and Sefton Hill, Arkham City is based on the franchise's long-running comic book mythos. In the game's main storyline, Batman is incarcerated in Arkham City, a massive new super-prison enclosing the decaying urban slums of fictional Gotham City. He must uncover the secret behind the sinister scheme, "Protocol 10", orchestrated by the facility's warden, Hugo Strange. The game's leading characters are predominantly voiced by actors from the DC Animated Universe, with Kevin Conroy and Mark Hamill reprising their roles as Batman and the Joker, respectively. The game is presented from the third-person perspective with a primary focus on Batman's combat and stealth abilities, detective skills, and gadgets that can be used in both combat and exploration. Arkham City expands Batman's arsenal of gadgets and combat attacks and offers a more open world structure, allowing the player to complete side missions away from the primary storyline.

The game received critical acclaim, particularly for its narrative, character and world designs, and Batman's combat and navigation abilities. It was tied for the highest-rated video game of 2011 according to review aggregator Metacritic, and was the recipient of several awards including: Game of the Year, Best Action Game, Best Action Adventure Game, Best Adventure Game, and Best Original Score from various media outlets. Arkham City was followed by several additional releases: a spin-off mobile game, Batman: Arkham City Lockdown, on December 7, 2011; a Game of the Year edition containing all of the game's downloadable content on May 29, 2012; and Wii U and OS X versions in November and December 2012, respectively. A successor, Batman: Arkham Origins, was released in October 2013, and a narrative sequel, Batman: Arkham Knight, is scheduled to be released in October 2014.

Gameplay
Arkham City is an open world action-adventure game that incorporates elements of stealth game tactics. It is presented from the third-person perspective, showing the playable character on screen and allowing the camera to be freely rotated around them. The Arkham City facility is open to the player from the beginning of the game, allowing them to freely travel anywhere within its boundaries. The player can opt to move silently throughout the game, using a combination of gadgets and stealth moves to sneak up on enemies and incapacitate them. Batman can use his cape to glide around the city, diving downward and swooping upwards to extend his flight, and he can use the grapnel gun's retracting rope to attach to out-of-reach ledges. As Batman, the player is able to use "Detective Vision", a visual mode that highlights elements of interest on-screen, such as character status, collectables, and clues; the mode is also used to perform forensic activities such as tracking the source of a sniper rifle round. The player has access to an in-game criminal database which includes forensic puzzles, as well as a network for hacking communication frequencies.

Using an improved version of the Freeflow combat system from Arkham Asylum, the player can now counter multiple blows simultaneously, catch hurled projectiles, attack aerially, and administer a succession of consecutive strikes. Many of Batman's gadgets can now be used in combat. Enemies are armed with varying levels of armor and weapons; attacks from basic weapons like baseball bats and lead pipes inflict minor damage and can be countered, while guns deal significant damage. Certain enemies must be disarmed in specific ways before they can be neutralized in combat: enemies with stun batons can only be attacked from behind; enemies with shields require aerial attacks to disarm; and enemies wearing body armor must be stunned with rapid successive strikes before they can be harmed. Larger enemies must be tackled with stuns and combo attacks, and can be manipulated to take out their allies. Disputes between gangs allied to rival villains often spark turf wars, which complicate the player's ability to move about Arkham City. Combat, among other actions, rewards the player with experience points that allow the player to periodically level Batman up and purchase upgrades for his Batsuit, gadgets, and combat and stealth skills. Each category contains approximately 15 different upgrades. For instance, an upgraded grapnel gun can be used to remotely disarm enemies, while a combat upgrade makes it easier to activate special attacks.

Some gadgets obtained in Batman: Arkham Asylum are present at the start of Arkham City, while others become available during play. Most of these have improved or new capabilities; for example, the Cryptographic Sequencer, used for hacking security consoles, can also monitor shortwave radio channels, while the line launcher can now be deployed as a tightrope or alter direction during flight. Other equipment returning from the first game include: a remote-controlled batarang; Explosive Gel that can now be detonated to knock down enemies in combat; and the grapnel gun, which can now be used while gliding to facilitate transportation. New equipment in Batman's arsenal include: smoke bombs that disorient opponents and assist with stealth tactics; a Remote Electric Charge (REC) gun that can stun enemies and temporarily power motors; Freeze Blast grenades that encase targets in ice and can be used within water to create makeshift platforms; and the Disruptor, which can remotely disable guns and explosive mines.

The game has approximately 40 hours of gameplay, with the main campaign lasting 25 hours and side missions lasting 15 hours. The side missions, which can be attempted at any time, feature prominent characters from the Batman universe. One such character, the Riddler, provides 440 optional "Riddler challenges" to solve. Most of these challenges consist of collecting trophies hidden throughout the city through the cunning use of gadgets to disable traps and barriers. The player can mark Riddler trophies on the in-game map once found if they do not initially have the necessary equipment to complete the puzzle. Additionally, the player can reveal the locations of Riddler trophies on the map by identifying the Riddler's henchmen with "Detective Vision" and interrogating them, which requires the player to save the henchmen for last in combat among a wave of enemies. There are also environmental challenges which require the player to solve riddles by locating a specific item or location (which are rewarded with stories relating to the answer), and to locate question marks painted around the city, some of which can only be viewed in whole from certain vantage points. After completing a select number of challenges, Batman must rescue a civilian hostage held in one of the Riddler's death traps.

After completing the story mode on "normal" or "hard" difficulties, a "New Game Plus" mode is unlocked, enabling the player to replay the game with all of the gadgets, experience, and abilities that they have attained; enemies are tougher and the on-screen icon that warns players of imminent attacks is disabled. Arkham City features a series of challenge maps separate from the game's story mode. The maps focus on the completion of specific goals, such as eliminating successive waves of enemies in combat, subduing patrolling enemies while employing stealth, or traveling to a specific location as efficiently as possible. The methods and variety of abilities used to achieve these goals earn an overall performance score that is ranked online against other players.

Catwoman is another playable character available via the Catwoman campaign, which was initially downloadable content (DLC) on PlayStation 3 and Xbox 360 consoles but was later included with the PC version and Game of the Year editions. Catwoman's campaign features her own heist-focused storyline that intersects with the main story at specific points in the game. Her combat emphasizes agility and allows for the use of unique weapons such as clawed gauntlets, bolas, and her iconic whip. A portion of the Riddler challenges are specific to Catwoman and can only be completed by her. Batman's allies Robin and Nightwing are also playable via optional DLC and feature their own combat abilities and gadgets. Both characters are available in the challenge maps, while Robin has his own main story narrative.

The PlayStation 3 and Xbox 360 versions of Arkham City include a stereoscopic 3D (S3D) mode for 3D HDTVs and for 2D HDTVs via Inficolor 3D glasses, while the PC version supports Nvidia 3D Vision on compatible monitors. It uses TriOviz for Games Technology, which is integrated with Unreal Engine 3. The Wii U version uses the Wii U's touch screen controller to let the player manage Batman's equipment and upgrades, selectively detonate Explosive Gel placements, and view a map of the city. The Wii U version adds a Sonar mode which highlights points of interest nearby, and the Battle Armored Tech Mode (BAT Mode) that allows Batman to accrue energy during combat and, when activated, inflict increased damage.

Black Mask (also voiced by North), Killer Croc (Steven Blum), and Freeze's wife, Nora Fries, make cameo appearances in the game.

Setting
The events of Arkham City are set one year after Batman: Arkham Asylum. Quincy Sharp, the asylum's erstwhile director, has taken sole credit for halting the Joker's armed siege, using this distinction to become mayor of Gotham City. Declaring both the asylum and Blackgate Penitentiary no longer suitable to contain the city's detainees, Sharp's administration orders both facilities closed and he purchases Gotham's most notorious slums, converting them into an immense prison enclosure known as Arkham City. This facility is subsequently placed in the care of psychiatrist Hugo Strange—who is secretly manipulating Sharp—and monitored by a rogue private military firm, TYGER Security. Strange permits inmates to do as they please, provided escape is not attempted. A wary Batman maintains his own vigil over the new project, concerned that the chaotic situation there will get out of hand. Meanwhile, the Joker is suffering from a potentially fatal disease caused by his previous consumption of the Titan formula, an unstable steroid serum which turns men into maddened monsters.

Plot
At a press conference held by Bruce Wayne to declare his opposition to Arkham City, TYGER mercenaries arrest and imprison him in Arkham City. Hugo Strange discloses his knowledge of Wayne's dual identity as Batman before releasing him into the prison's criminal populace. While Strange prepares to commence "Protocol 10", Wayne obtains his equipment via airdrop from Alfred Pennyworth, allowing him to become Batman. He first saves Catwoman from being executed by Two-Face, who hopes to gain respect by murdering her. After Joker attempts to assassinate Catwoman, Batman tracks him to his hideout in the Sionis Steelmill, believing Joker may know the truth behind Protocol 10.

There, Batman learns that the unstable properties of the Titan formula are mutating in Joker's blood, gradually killing him. Joker captures Batman and performs a blood transfusion on him, infecting him with the same fatal disease. Joker also reveals that Gotham hospitals have been poisoned with his infected blood. Desperate to save himself and innocent citizens, Batman seeks out Mr. Freeze, who had been developing a cure but has since been kidnapped by the Penguin.

Tracking Penguin to the Cyrus Pinkney National History Institute, Batman defeats his forces, his imprisoned monster Solomon Grundy, and ultimately the Penguin himself, before liberating Mr. Freeze. Freeze tells Batman that he has already developed the cure, but its instability renders it useless. Batman deduces that the restorative properties of Ra's al Ghul's blood can complete the cure. Batman tracks one of Ra's al Ghul's assassins to his underground lair, leading Batman into a confrontation with Ra's and his daughter Talia, Batman's former lover. With Ra's al Ghul's blood, Freeze is able to develop an antidote, but it is stolen by Harley Quinn before Batman can use it.

When he returns to the Joker, Batman finds him restored to health. While the two fight, Strange activates Protocol 10, which is revealed to be a scheme to wipe out the entire population of Arkham City and destroy the criminal element of Gotham. The TYGER troops begin mass executions, while Strange launches missile strikes from his base in Wonder Tower. A missile hits the steelmill, burying Batman under rubble. Before Joker can take advantage of the situation, Talia arrives and offers him immortality in exchange for sparing Batman's life. After escaping with the help of Catwoman, Batman is convinced by Alfred to end Protocol 10 before pursuing Talia and Joker.

Batman infiltrates Wonder Tower and disables Protocol 10. Ra's al Ghul is revealed to be the true mastermind behind Arkham City and mortally wounds Strange for failing to defeat Batman. With his dying breath, Strange activates "Protocol 11", the self-destruction of Wonder Tower. Batman and Ra's escape, but Ra's commits suicide rather than risk capture. Joker contacts Batman, threatening to kill Talia unless Batman meets him at the Monarch Theater. Once Batman arrives, Joker demands the cure but is stabbed and apparently killed by Talia while distracted. While Talia admits to stealing the cure from Quinn, she is killed by a second Joker, still stricken with the disease. The healthy Joker that Talia stabbed then reanimates into the shapeshifting Clayface, who is revealed to have been masquerading as a healthy Joker at the ailing villain's request.

Batman incapacitates Clayface, but Joker blows up the theater floor, sending Batman plummeting into Ra's' lair below. Batman destroys Ra's' rejuvenating Lazarus Pit before the Joker can use it, and drinks a portion of the antidote. Batman debates curing his foe, but before he can act, Joker attacks Batman and inadvertently smashes the antidote vial. Batman admits that in spite of everything Joker had done, he would have saved him. After Joker finally succumbs to his illness and dies, Batman carries his body out of Arkham City. As Commissioner Gordon asks what happened, Batman places Joker's body on the hood of a police car and leaves in silence.

Concept
Rocksteady conceived an idea for a sequel before development of Arkham Asylum had concluded, developing ideas for both the story and setting so the games' narratives could be effectively connected; a secret room was hidden in the asylum warden's office in Arkham Asylum containing hints of how the sequel would progress, including blueprints for the Arkham City prison; the blueprints are quite similar to its final layout in Arkham City. The original idea was to take the game out of the asylum setting and onto the streets of Gotham City while retaining the level of design detail put into the asylum. To that end they wanted to include locations from the Batman mythos that were notable and meaningful to the character, instead of a series of generic streets; Rocksteady was initially unsure how technical considerations would limit the scope of this idea.

Serious development of the game's story and concept started in February 2009, as teams were moved from Arkham Asylum to Arkham City's development as they completed the work on that game. By the time they had programmed Batman to dive and glide between buildings of the asylum, the adaption of the gameplay to the city was considered natural. Rocksteady decided to not include the Batmobile, because it would be unable to travel on the city's broken terrain, Batman's gliding provided a sufficient means of transportation, and it was considered that putting Batman in any vehicle would make it a completely different game. Sefton Hill, Arkham City's director from Rocksteady Studios, stated that a key goal for the game was to deliver the "'Batman in Gotham' feeling." The sequel was described by Conroy as "really, really dark". While relating the game's dark nature to the animated movie Batman Beyond: Return of the Joker, Conroy also said, "It involves a lot of the villains and it goes to that area – it's that dark."

Design
As part of the "Batman in Gotham" design philosophy, Batman's arsenal of moves and actions were expanded. Although the team developed several ideas for new moves, gadgets and abilities, they only went forward with those that they felt would be authentic to Batman. They also chose to have Batman start the game with access to the gadgets unlocked in Arkham Asylum, to convey the impression that Batman is fully prepared for the inevitability of things going wrong in Arkham City. The studio reviewed the play and combat systems used in Arkham Asylum, and built the new moves as natural extensions of the existing system as a means to "add even more depth and gameplay instead of changing them fundamentally". The number of animations were doubled to reflect the larger arsenal of moves at the player's disposal. The X-ray-like "Detective Vision" mode used to highlight certain objects in-game was redeveloped for Arkham City because it was considered to be too useful in Arkham Asylum, resulting in some players using it throughout almost the entire game; the visual effect also obscured the game's design aesthetic. One idea was to introduce a time limit on its use, but it was considered that Batman "wouldn't make a gadget like that". Instead, the mode was designed to be difficult to use in certain situations such as obscuring navigational information, and combat where enemy strikes will blur the screen when "Detective Vision" is active. Rocksteady art director David Hego described the new "Detective Vision" as an "augmented reality mode".

Another way the developers wished to enhance the player's Batman experience was through the larger game world. Arkham City has a virtual footprint five times larger than that of Arkham Asylum, and the navigational aspects were improved to offer the player "the freedom and exhilaration of gliding down alleyways and soaring above the skyline". Though the concepts were compared to an open world game, Hill notes that such freeform nature would not be appropriate for a Batman game because it would inhibit the atmosphere they wanted to create, and that Arkham City was designed to challenge the player to think like Batman to survive. To counterbalance the larger game world, the developers also sought to include more challenges and side missions while keeping the player alert as to the primary mission, such that the players constantly are aware of "extreme pressure of the challenges that they face". The Riddler Trophies were designed towards the end of the game's development and were incorporated into every area of the map without overpopulating it, resulting in 440 trophies. Rocksteady aimed to make the player think creatively when collecting trophies by requiring the use of gadgets to solve puzzles, rather than placing the trophies in obscure areas of the map as mere collection items.

With the open game world, Rocksteady included more villains to create challenges for Batman. Hugo Strange was selected as a primary antagonist, as his power and controlling manner help maintain the lockdown on Arkham City once Batman enters. Strange is aware of Batman's true identity, making Batman "vulnerable and exposed in a way that he has never been before", according to Hill. He noted that Strange is a character new to many players but that his backstory and character are detailed throughout the game. Catwoman was also included based on her long history with Batman, though she was given her own agenda running parallel to the events within Arkham City. Catwoman's missions initially ended with her coming to Batman's aide, but late in development, the developers decided to give the player an alternate choice, allowing them to have the morally-grey Catwoman leave the city with her loot; the addition was implemented in two days. Batman's sidekick Robin also appears, featuring a shaved head and contemporary costume design that were intended to move away from his traditional "Boy Wonder" image. Senior concept artist Kan Muftic explained: "Our vision of Robin is the one of a troubled young individual that is calm and introverted at times, but very dangerous and aggressive if provoked. The shaved head is inspired by cage fighters, because we thought that Robin might be doing that in his spare time to keep him on his toes. Still, we kept all the classic trademarks of Robin's appearance, such as the red and yellow colors of his outfit, the cape and the mask." Rocksteady originally did not plan to include Robin in the main story but later decided to as an authentic means of delivering new gadgets to Batman, as well as to introduce their version of the character and his relationship with Batman.

Rocksteady intended for Batman, Catwoman, and Robin to offer three different playing experiences. Other villains from Batman's comic history were selected to show that the prison was a melting pot of people from Gotham. The developers believed that providing a small part of each villain's story rather than focusing on a select few allowed the player to meet many more characters and effectively conveyed the feeling of being in a superprison filled with supervillains. Rocksteady decided early on that the Joker would die in the story, and developed the idea of him poisoning Batman with the same affliction, in order to show how the two diametrically opposed characters would interact in pursuit of a shared goal. Warner Bros. and Dini did not oppose killing off the character as long as it was not done for shock value, and as long as they made it clear that Batman was not at fault, since he would not intentionally kill someone.

The developers had considered adding a multiplayer element to the game, but ultimately decided against it. According to Hill, "If we use all of the energy that is required to create multiplayer and instead focus this on the single player, would that deliver a better overall game?", and decided in the affirmative.

Variety was added to the city itself, as certain areas were designed around the villains that control that particular territory. Dax Ginn, marketing game manager at Rocksteady Games, said, "If you move into Joker's territory, you get a very Joker-ized experience, and all the artwork on the buildings – whether that's graffiti, signage, or whatever it might be – gives you a dense kind of Joker experience. So our art team has really put a lot of effort in making that sort of transition between one turf zone to another – really helping the player feel like they're making a physical transition into another emotional space." The architecture was imbued with 19th century Art Nouveau design, such as Strange's Wonder Tower which was inspired by the Eiffel Tower, while characters designs employed a modern Hyperrealism style. To keep the environments interesting, base color schemes such as Mr Freeze's ice-themed area, Joker's fire-themed steel mill, and Poison Ivy's jungle-themed area were populated with contrasting elements: for example, the steel mill uses large, white clown faces to contrast the oranges and reds used throughout. To develop the expanded environment of Arkham City and build a "natural urban environment" for Batman, Rocksteady expanded its workforce from 75 to over 100 people.

Music
The game's release was accompanied by two albums of music released by WaterTower Music. Batman: Arkham City – Original Video Game Score was released on October 18, 2011, and features 19 tracks written for the game by Arkham Asylum composers Nick Arundel and Ron Fish. Batman: Arkham City – The Album was released on October 4, 2011, via CD and digital download. The album contains 11 original songs inspired by the game from mainstream artists including Daughtry, Panic! at the Disco, and Coheed and Cambria. An additional song was made available via the Collector's edition of the album, and the Deluxe edition included a portion of Arundel's original score.

Marketing
Arkham City's marketing campaign was designed to reach an audience outside of superhero fans and appeal to consumers who are attracted to games like the first-person shooter series Call of Duty. Warner Bros.' marketing team decided that Batman's status as a cultural icon and superhero was unavoidable, so they decided to emphasize other elements of the character that could appeal to fans of first-person shooters and action games. Black and white photographs of iconic personalities like inventor Steve Jobs and actor James Dean served as inspiration and a basis for the final marketing campaign used in advertisements and the game's cover art. The imagery, highlighted with blood and bathed in light was considered to move away from the classic superhero image and refocus on Batman's humanity. The black and white campaign was featured on 120 magazine covers and was targeted towards approximately 15 million consumers across a variety of social media and Warner Bros. products, in addition to a series of viral marketing videos and stunts involving actors in costume attending press-related events. By April 2012, three gameplay trailers had gained approximately 6 million views. The viral segment of the campaign involved several audio recordings between characters from the game including Hugo Strange, Quincy Sharp, Riddler and the Penguin; each recording could be found by solving a puzzle. The entire campaign spent over a year in development, producing artwork, videos, DLC, printed adverts, billboards and events, and was estimated to have cost at least $10 million.

A six-issue, limited monthly comic series, also titled Batman: Arkham City was released on May 11, 2011. The series bridges the plot between Arkham Asylum and Arkham City. It was written by Paul Dini with art by Carlos D'Anda. Warner Bros. also developed toys based on the characters through Mattel, Hallmark cards, batarang-shaped videogame controllers, and a variety of apparel by Converse, Eckō Complex, C Life, New Era, and Briefly Stated.

Toys "R" Us in Times Square New York City, released 500 copies of Batman: Arkham City on Monday, October 17, one day before the game officially hit shelves. The first 100 customers to pre-order a copy through the store's "Personal Shopping Department" had a chance to get their game autographed by DC Entertainment co-publisher Jim Lee, Batman voice actor Kevin Conroy, and Arkham City game director Sefton Hill. The remaining 400 copies of Arkham City could be purchased at the event, unautographed.

Reception
Batman: Arkham City received critical acclaim. Aggregating review websites GameRankings and Metacritic gave the PlayStation 3 version 96.12% and 96/100, the Xbox 360 version 93.88% and 94/100,  and the PC version 90.43% and 91/100.

Game Informer's Andrew Reiner awarded the game a perfect 10 score, labeling it "the best licensed video game ever made". Reiner said that the game could be the biggest and "most enjoyable timesink" of 2011, and concluded that the game surpassed every standard set by Batman: Arkham Asylum "in every way and stands tall as one of Batman's greatest moments." Joystiq's Griffin McElroy praised the attention to detail, and mechanical excellence of the game environment, crediting Rocksteady for "breathing life into a staggeringly beautiful world; one which hums not only with opportunity, but ambition". However, McElroy criticized the game narrative as a series of excuses to encounter villains that were "one-dimensional punching [bags]", and that the character dialogue was clichéd. McElroy was also critical of the Riddler challenges, stating that they were "frustrating" when the player lacks the necessary items to complete them.

Eurogamer's Christian Donlan considered that the game lacked the same "surprise" as its predecessor, but praised the overall improvement of bosses, animations and the scope of activities available. Donlan said that the game environment was intricate and very detailed, and the abilities provided for its traversal made it "hard not to feel like the world's greatest detective, on patrol". IGN's Greg Miller said "the voice acting, the challenges, the amazing opening, the unbelievable ending and the feeling of being the Dark Knight—these are the things that standout". Miller said that the Catwoman missions were a fun change of pace from the main gameplay, and that he "adored" the option to replay the game with unlocked abilities and more difficult enemies.

The Daily Telegraph's Tom Hoggins praised the game's sense of progress in discovering and mastering the character abilities, and the "show-stopping brutality" of the improved combat system. Hoggins highlighted the Catwoman campaign as a "delight" and fitting lithe contrast to Batman's strength, but lamented the campaign's short length. The Guardian's Nick Cowen labeled it the best Batman game of all time, praising the variety of side missions and content, the large cast of iconic characters, and the satisfying challenge of the Riddler missions. The Australian Official PlayStation Magazine awarded a perfect score of 10 stating that the game "is not only the best superhero game ever made, it's one of the best games ever made ... it brings the Caped Crusader's world to life better than any comic, movie or television show before it". Play3 (Germany) awarded a score of 92%, calling it "the best superhero game ever made". Games Master awarded a score of 97%, saying it is "the gold standard by which all future videogames should be judged".

Batman: Arkham City Armored Edition for Wii U received a mixed reception. GameRankings provided a score of 84.88%, and Metacritic provided a score of 85/100. Eurogamer's Richard Leadbetter was critical of technical performance including issues with visual quality and inconsistent framerate. EGM's Ray Carsillo said that the optional B.A.T. system made certain battles too easy. Carsillo also said it was the "clearly inferior version" of the game due to glitches and "tacked on gimmicks". Nintendo World Report's Patrick Barnett wrote that certain uses of the Wii U controller made it "the best way to experience Arkham City", but that some new features were a "nuisance". Barnett added that it was "on par, if not better, visually", than its counterparts. Joystiq's JC Fletcher opined that the persistent map screen and touch screen interface were appreciated, and complimented the use of augmented reality to explore crime scenes. Game Revolution's Blake Peterson praised the real-time management of information, upgrades and equipment that he considered made Batman more vulnerable, although Barnett included this as a point of criticism.

For the Harley Quinn's Revenge DLC, IGN's Greg Miller scored the content 9 out of 10 and gave it an Editor's Choice designation. Miller said that it "is what downloadable content should be", but criticized the lack of variety in the missions and the lack of conclusion to some plot threads. Eurogamer's Christian Donlan gave the DLC a score of 7 out of 10, and said that Harley Quinn worked as well as the Joker as a narrative focus. Donlan said that Robin was "enormous fun to play", but criticized the DLC for not offering anything not present in the main game. Kotaku's Stephen Totilo was critical of the DLC, saying that it diminished his desire to replay the main game and describing it as "delicious a dessert as a poison-filled Joker pie to the face". Totilo said it presented an emotionless, inconclusive journey, composed of unused material from the main game.

Sales
Worldwide, the game sold two million units in its first week of approximately 4.6 million shipped units, compared to Arkham Asylum which sold 4.3 million units in its entire release. This made Arkham City one of the fastest selling games ever. On February 8, 2012, it was announced that over six million units of the game had been shipped since release.

Technical issues
During launch week, issues were found to exist in the code-restricted content. Some customers discovered the code to be missing from their copy, preventing them from obtaining the Catwoman story missions. The problem was reported by customers in Canada, the United States, and the United Kingdom. Warner Bros. issued a statement claiming that the missing codes had affected less than 0.5% of customers. Upon release in the United Kingdom, a technical issue rendered the game unplayable for some players, booting them from the game with an error message that the "downloadable content is corrupt." Rocksteady European community manager Sarah Wellock claimed that the fault lay with the PlayStation Network and Xbox Live online systems.

In early November 2011, Rocksteady confirmed that it was investigating reports by numerous users that save files for the Xbox 360 version of the game were being erased without prompting, resulting in players losing their progress and being unable to complete the game. On launch, performance issues arose for the PC version when DirectX 11 features were enabled; the developer acknowledged the inconvenience and recommended to run the game with DirectX 9 while a title update was released to address this matter.
