.hack simulates an MMORPG; players assume the role of a participant in a fictional game called The World. The player controls the on-screen player character Kite from a third-person perspective but first-person mode is available. The player manually controls the viewing perspective using the game controller. Within the fictional game, players explore monster-infested fields and dungeons, and "Root Towns" that are free of combat. They can also log off from The World and return to a computer desktop interface which includes in-game e-mail, news, message boards, and desktop and background music customization options.{{cite web | author=Smith, David | date=2002-08-07 | title=.hack Infection Vol.1 | website=IGN | url=http://ps2.ign.com/articles/367/367010p1.html | access-date=2010-06-29 | archive-url=https://web.archive.org/web/20110629133813/http://ps2.ign.com/articles/367/367010p1.html | archive-date=June 29, 2011 | url-status=live | df=mdy-all }} The player may save the game to a memory card both from the desktop and within The World at a Save Shop. A Data Flag appears on the save file after the player completes the game, allowing the transfer of all aspects of the player character and party members to the next game in the series.{{cite web | author=Dunham, Jeremy | date=2003-03-19 | title=.hack//MUTATION (Part 2): First Impressions | website=IGN | url=http://ps2.ign.com/articles/390/390018p1.html | access-date=2010-06-29 | archive-url=https://web.archive.org/web/20110629133851/http://ps2.ign.com/articles/390/390018p1.html | archive-date=June 29, 2011 | url-status=live | df=mdy-all }}

The series is typical of action role-playing games, in which players attack enemies in real time. The game's action pauses whenever the menu is opened to select magic to cast, items to use, or skills to perform. The player directly controls Kite and the other characters are controlled by artificial intelligence. The player may either provide the computer-controlled characters with guidelines ("attack", "first aid", "magic", etc.) or issue direct commands. Most hostile creatures are contained within magic portals and combat will not begin until the player character approaches the portal and releases the monsters inside. Kite possesses a unique ability called "Data Drain" which allows him to transform these enemies into rare items.{{cite web | author=Torres, Ricardo | date=2002-12-03 | title=.hack infection part 1 Preview | work=GameSpot | publisher=CBS Interactive | url=http://www.gamespot.com/ps2/rpg/hackpart1infection/news.html?sid=2899191&mode=previews | access-date=2010-06-29 | archive-date=December 26, 2018 | archive-url=https://web.archive.org/web/20181226080830/https://www.gamespot.com/articles/hack-infection-part-1-preview/1100-2899191/ | url-status=dead }} Many boss monsters are known as "Data Bugs"—enemies with corrupted data which gives them infinite health. Data Drain is used to repair the damaged monsters' data and render them vulnerable but its use increases Kite's level of infection, randomly causing harmful side effects. The infection can be cured by defeating enemies without Data Drain.{{cite book |title=.hack//Infection North American instruction manual |year=2002|publisher=Bandai Games|page=14}}

Root Towns are non-combat areas of The World where the player may restock items, buy equipment, or chat and trade with other players of The World. In many towns, the player may also raise a sentient, pig-like creature called a Grunty, which can be ridden in fields and in later games raced for prizes. A blue portal called the Chaos Gate is used to travel between towns (called "servers") and to access the fields and dungeons where battles occur. A three-word password system controls the characteristics of each area; attributes such as the prevalence of monsters or items change depending on the properties of each word in the password phrase. Certain plot-related areas have restricted access, but the player character has an ability called "Gate Hacking" which allows him to access these areas using "Virus Cores" obtained through Data Drain.

The .hack games are set in an alternate history Earth, in the year 2010. After a computer virus called "Pluto's Kiss" crashes nearly every computer in the world, access to the Internet is closed to the general public to address security concerns.{{cite video game|title=.hack//Mutation |developer=CyberConnect2 |publisher=Bandai |date=2003-05-07 |platform=PlayStation 2|quote=News: The end of this year marks five years since "Pluto's Kiss," the network crisis that nearly destroyed the world.}} After two years without the Internet and online games, a MMORPG called The World is released.{{cite video game|title=.hack//Infection |developer=CyberConnect2 |publisher=Bandai |date=2003-02-11 |platform=PlayStation 2|quote=News: BANDAI also announced that it will be compatible with the current key network OS, "ALTIMIT," and the device will also act as an internet terminal as well.

The World was developed by a German programmer named Harald Hoerwick; its backstory is based on the Epitaph of Twilight, an epic poem by Emma Wielant. Her death inspired Hoerwick to create the game. Elements of the poem are coded into the game's programming.{{cite video |date=2004-01-14 |title=.hack//Liminality Vol. 4 |medium=DVD |publisher=Bandai |quote=Easter egg: In the "Epitaph of Twilight," the one who will destroy the world is depicted as the Cursed Wave, or the Abominable Wave. / ... / In the game, a ripple-like shockwave is emitted by the Eight Phases of Morganna...

He eventually decided to create Morganna, a self-evolving limited AI disguised as a game system that would learn and grow, eventually giving birth to the ultimate AI.}} To this end, Hoerwick inserted functions into the system which monitor and extract behavioral data from millions of the game's players to aid in the AI's learning process. After Hoerwick's death, these pieces of code became black boxes to the current developers, who cannot fathom their purpose, yet are critical to the proper functioning of the game.{{cite video |date=2004-01-14 |title=.hack//Liminality Vol. 4 |medium=DVD |publisher=Bandai |quote=Easter egg: Black boxes, mysterious portions of the program that function autonomously, have baffled CC Corp. developers.}}

The main protagonist of .hack is Kite, a new player of The World whose friend Orca becomes comatose under mysterious circumstances. Kite is joined by nearly twenty other players in his quest to solve the mystery of the coma victims. The players who have the greatest impact on the success of Kite's mission are BlackRose, a fellow newbie to The World whose brother is also in a coma; Balmung, a legendary player who seeks to eliminate sources of corruption in the game he loves; and Wiseman, an information broker who becomes a key strategist for Kite's team. Helba, a professional hacker, and Lios, a reluctant system administrator, also aid in Kite's efforts to rescue the coma victims. Two non-human characters play important roles in the story: Aura seeks to complete her growth into the ultimate AI, while Morganna, an AI who rebels against her task of nurturing Aura, acts as the unseen primary antagonist.

In .hack//Infection, Kite's friend Orca invites him to play The World. In the first dungeon they visit, they encounter a girl in white, Aura, being chased by a humanoid monster. Aura tries to entrust Orca with an item called "the Book of Twilight", but the monster attacks him, crashing The World's servers. Kite's player discovers that Yasuhiko, Orca's player, has fallen comatose after the attack, and resolves to discover the cause.{{cite video game|title=.hack//Infection |developer=CyberConnect2 |publisher=Bandai |date=2003-02-11 |platform=PlayStation 2|quote=Kite: The next day, I found out that Yasuhiko had been hospitalized.}} Kite meets BlackRose, who takes him to a cathedral where they are attacked by a headless swordsman. The legendary player Balmung appears and defeats it, but the monster revives itself as a Data Bug.{{cite video game|title=.hack//Infection |developer=CyberConnect2 |publisher=Bandai |date=2003-02-11 |platform=PlayStation 2|quote=Balmung: It's a bug from a computer virus. The virus is rewriting the data. It has a HP that is – infinite.}} The Book of Twilight then activates, altering Kite's character data and giving him the Twilight Bracelet. He uses its Data Drain to correct the swordsman's code, allowing Balmung to kill it. Balmung accuses Kite of causing the viral infection spreading through the game, and leaves.{{cite video game|title=.hack//Infection |developer=CyberConnect2 |publisher=Bandai |date=2003-02-11 |platform=PlayStation 2|quote=Balmung: That skill... You are the same as the virus.}} Kite and BlackRose decide to cooperate to help the coma victims. After investigating a number of leads, Kite and BlackRose track down Skeith, the creature that put Orca into a coma. They defeat Skeith. The remnants of Skeith attracts a much larger enemy named Cubia, which defeats Kite and his party. Helba then drives Cubia away.{{cite video game|title=.hack//Mutation |developer=CyberConnect2 |publisher=Bandai |date=2003-05-07 |platform=PlayStation 2|quote=Helba: With the help of the bracelet, [Kite] and his party succeeded in destroying Skeith.}}

In .hack//Mutation, Kite and BlackRose encounter system administrator Lios, who declares Kite's bracelet to be an illegal hack.{{cite video game|title=.hack//Mutation |developer=CyberConnect2 |publisher=Bandai |date=2003-05-07 |platform=PlayStation 2|quote=Lios: [Installation of an illegal effect] requires that you delete your character.}} He tries to delete Kite's character data, but fails due to Kite's data being encrypted by the Book of Twilight. Helba intervenes, and convinces Lios to observe Kite for the time being.{{cite video game|title=.hack//Mutation |developer=CyberConnect2 |publisher=Bandai |date=2003-05-07 |platform=PlayStation 2|quote=Helba: Silencing is not the only means of control. Why don't you observe them for a little while longer?}} Lios directs them to an area where they find Innis, a monster with powers similar to Skeith's. Upon defeating Innis, Kite receives an e-mail from Aura, who reveals that she is an AI. They travel to an area to meet her; but Cubia attacks them, and they repel the monster with difficulty.{{cite video game|title=.hack//Mutation |developer=CyberConnect2 |publisher=Bandai |date=2003-05-07 |platform=PlayStation 2|quote=Helba: You defeated Cubia. I'm impressed.}} Short on leads, they contact Wiseman, who is intrigued by Kite's bracelet. He suggests that Skeith and Innis are based on the "Cursed Wave", an antagonistic force featured in the poem Epitaph of Twilight, upon which The World is based. Wiseman helps grant them access to Net Slum, a place known as a paradise for hackers and wandering AIs. Upon arrival, another Cursed Wave monster called Magus attacks them. They defeat it and return to the Root Town, where they discover that the computer virus has spread to The World{{'s}} main servers and into the real world.{{cite video game|title=.hack//Outbreak |developer=CyberConnect2 |publisher=Bandai |date=2003-09-03 |platform=PlayStation 2|quote=Helba: [Kite] and his party defeated Skeith, Innis, and Magus.

In .hack//Outbreak, Balmung realizes that he cannot end the situation on his own, and joins Kite's quest.{{cite video game|title=.hack//Outbreak |developer=CyberConnect2 |publisher=Bandai |date=2003-09-03 |platform=PlayStation 2|quote=Kite: But... it's really not something I can accomplish alone. Could you lend me a hand? / Balmung: You're... Of course!}} BlackRose tells Kite that her brother became comatose under similar circumstances as Orca, which renews both characters' determination.{{cite video game|title=.hack//Outbreak |developer=CyberConnect2 |publisher=Bandai |date=2003-09-03 |platform=PlayStation 2|quote=BlackRose: Do you want to know something? My brother fell unconscious here.}} Wiseman formulates a plan to combat the Cursed Wave, enlisting Helba's assistance. Their teamwork destroys the Wave monster Fidchell, but the aftermath causes networks in the real world to malfunction.{{cite video game|title=.hack//Outbreak |developer=CyberConnect2 |publisher=Bandai |date=2003-09-03 |platform=PlayStation 2|quote=Kite: The virus refused to remain in "The World" and began flooding our territory – the real world.}} Aura contacts Kite again, but their meeting is cut short by Cubia's reappearance. Lios, observing Cubia's power, agrees to join Kite, Helba, and the others to combat the Cursed Wave.{{cite video game|title=.hack//Outbreak |developer=CyberConnect2 |publisher=Bandai |date=2003-09-03 |platform=PlayStation 2|quote=Lios: I'll keep my promise. I will help you.}} In the resulting operation, the team pools their resources to defeat another Wave monster called Gorre, with no repercussions in the real world.{{cite video game|title=.hack//Outbreak |developer=CyberConnect2 |publisher=Bandai |date=2003-09-03 |platform=PlayStation 2|quote=Lios: All appears to have gone well. An investigation will still be needed, but... I guess you've succeeded for now.}}

.hack//Quarantine sees the current server becoming increasingly unstable. To fix the problem, Helba replaces it with a copy of the Net Slum.{{cite video game|title=.hack//Quarantine |developer=CyberConnect2 |publisher=Bandai |date=2004-01-14 |platform=PlayStation 2|quote=Kite: Net Slum? / Helba: It's a mirror of Ω server... which is mine.}} At the bottom of a dungeon, Kite encounters Mia, a member of his party. He discovers that Mia is actually another Cursed Wave monster named Macha, whom he reluctantly defeats.{{cite video game|title=.hack//Quarantine |developer=CyberConnect2 |publisher=Bandai |date=2004-01-14 |platform=PlayStation 2|quote=Mia: I only exist in "The World."}} Meanwhile, Cubia grows stronger, and Kite's team barely fends off its latest attack. In contrast, Operation Orca is a success as they destroy Tarvos, the next Wave monster. Kite seeks the advice of Harald Hoerwick, the creator of the game who survives beyond death through his AI incarnations. Aura appears and hints that Cubia is the "shadow" of Kite's Twilight Bracelet.{{cite video game|title=.hack//Quarantine |developer=CyberConnect2 |publisher=Bandai |date=2004-01-14 |platform=PlayStation 2|quote=Aura: Cubia is the shadow. When there is light burning in the darkness, a shadow is born. When the bracelet appeared in this world, Cubia was born as well.}} Cubia ambushes them and destroys the AI Harald. In their final battle, Kite recalls Aura's hint and has BlackRose destroy the bracelet, causing Cubia to fade away. Without the bracelet, the final Wave member, Corbenik, ambushes the party in Net Slum Root Town. With the aid of the spirits of the coma victims, Kite penetrates Corbenik's barrier. Aura sacrifices herself to end the battle, restoring the network to normal and reviving all the coma victims.{{cite video game|title=.hack//Quarantine |developer=CyberConnect2 |publisher=Bandai |date=2004-01-14 |platform=PlayStation 2|quote=Balmung: She was born.

Development for .hack began in early 2000 with the aim of shocking and surprising the player and creating a distinctive product.{{cite web | year=2003 | title=CESA Game Awards 2002-2003 | publisher=Japan Game Awards | url=http://awards.cesa.or.jp/2003/prizelist/awards06/index.html | language=ja | access-date=2010-12-12 | archive-url=https://web.archive.org/web/20110726153020/http://awards.cesa.or.jp/2003/prizelist/awards06/index.html | archive-date=July 26, 2011 | url-status=live | df=mdy-all }} CyberConnect2's president Hiroshi Matsuyama played a key role in developing the concept for the series. A number of core ideas, including "slaying dragons or being a thief in London" were explored, but these were rejected in favor of an "offline/online game".{{cite web|date=2003-05-16 |title=E3 2003: .hack Interview |website=IGN |url=http://ps2.ign.com/articles/403/403483p1.html |access-date=2010-06-29 |url-status=dead |archive-url=https://web.archive.org/web/20061231092204/http://ps2.ign.com/articles/403/403483p1.html |archive-date=December 31, 2006 }} Matsuyama said that this would give young gamers an opportunity to experience online play without paying monthly fees or needing powerful Internet connections. The developers looked at a number of MMORPGs such as Phantasy Star Online, Ultima Online, and Final Fantasy XI for inspiration, and drew influences from the prior works of character designer Yoshiyuki Sadamoto (Neon Genesis Evangelion) and scenario writer Kazunori Itō (Ghost in the Shell). Itō noted that casting the player into the role of a subscriber of The World creates a unique story-telling situation which draws the player deeper into the plot.{{cite web | author=Hunatsu, Minoru | date=2002-01-24 | title=バンダイ、ネット世界を中心に展開する壮大なRPG「.hack 感染拡大 Vol.1」、アニメDVDを同梱 | publisher=Game Watch | url=http://game.watch.impress.co.jp/docs/20020124/hack.htm | language=ja | access-date=2010-12-12 | archive-url=https://web.archive.org/web/20121009054305/http://game.watch.impress.co.jp/docs/20020124/hack.htm | archive-date=October 9, 2012 | url-status=live | df=mdy-all }}

From the start of its development, .hack was envisioned as a four-part series intended to mirror the four-volume story arcs found in manga. Matsuyama theorized that the act of transferring saved data across the four volumes would help to create a sense of the human drama embodied by the games' story and invest the player into the narrative.{{cite web | author=Hunatsu, Minoru | date=2002-05-20 | title=ネットワークゲームを舞台にした壮大なオフラインRPGバンダイ「.hack//感染拡大 Vol.1」をイベントで紹介 | publisher=Game Watch | url=http://game.watch.impress.co.jp/docs/20020520/bandai.htm | language=ja | access-date=2010-12-12 | archive-url=https://web.archive.org/web/20121009054657/http://game.watch.impress.co.jp/docs/20020520/bandai.htm | archive-date=October 9, 2012 | url-status=live | df=mdy-all }} The games were developed simultaneously alongside other elements of Project .hack such as .hack//Sign to emphasize the multimedia aspect of the franchise. The three-month gap between each game's release allowed the developers to make minor changes in response to criticisms. The games were packaged with bonus DVDs featuring episodes of .hack//Liminality, an original video animation (OVA) series that depicts events that occur concurrently with the games.{{cite web | author=Smith, David | date=2002-12-12 | title=.hack American Titles | website=IGN | url=http://ps2.ign.com/articles/380/380116p1.html | access-date=2010-06-29 | archive-url=https://web.archive.org/web/20110629133824/http://ps2.ign.com/articles/380/380116p1.html | archive-date=June 29, 2011 | url-status=live | df=mdy-all }} The developers intended the OVA series to depict fictional events happening in the real world outside the game.{{cite web | author=Conrad, Jeremy | date=2003-02-10 | title=.hack//Liminality - Vol. 1 In the Case of Mai Minase | website=IGN | url=http://dvd.ign.com/articles/385/385585p1.html | access-date=2010-07-26 | archive-url=https://web.archive.org/web/20100908154435/http://dvd.ign.com/articles/385/385585p1.html | archive-date=September 8, 2010 | url-status=live | df=mdy-all }} Players in Japan who purchased all four games were rewarded with .hack//Gift, an OVA parodying the .hack series.{{cite web | date=2003-03-29 | title=裏話が次々と披露！ 「.hack//感謝拡大」開催！ | publisher=Softbank Publishing | url=http://gamez.itmedia.co.jp/games/gsnews/0303/29/news02.html | language=ja | access-date=2010-12-12 | archive-url=https://web.archive.org/web/20110721222510/http://gamez.itmedia.co.jp/games/gsnews/0303/29/news02.html | archive-date=July 21, 2011 | url-status=live | df=mdy-all }} After the completion of the series, the development team produced .hack//frägment, a game using the same engine as the .hack series with an online multiplayer component. The aims of .hack//frägment were to allow the developers to watch player interactions in an online environment and to gauge interest in an online .hack game.{{Cite web |url=http://latestechnews.net/clash-royale-hack/ |title=online .hack game |access-date=June 29, 2016 |archive-url=https://web.archive.org/web/20170218034715/http://latestechnews.net/clash-royale-hack/ |archive-date=February 18, 2017 |url-status=dead |df=mdy-all }}

Critics gave the series mixed reviews. .hack//Infection received the most positive reviews of the series; critics were intrigued by the games' unique premise.

He also called Bandai's decision to add 60 to 80 hours of padding to the game, split it into four full-priced products, and release these as a series disappointing. Nutt was similarly disappointed with the final game, awarding it two stars out of five. He wrote that the story was well-presented and excellent, but that it was only present in the game's first and last quarters. He was satisfied by the game's ending and loved its story, style, and characters, but grew tired of the game's "endless chains of chambers, these easily-defeated enemies, this total lack of strategy". The Game Informer reviewer hoped to see a more effective implementation of .hack{{'}}s concept in the future.{{cite news | magazine=Game Informer | date=February 2004 | title=.hack Quarantine Review | publisher = GameStop| page=103}} Japanese magazine Famitsu Weekly gave the .hack games scores in the 29 to 30 out of 40 range, indicating average reviews. However, the Japanese Computer Entertainment Supplier's Association (CESA) honored the series for its combination of different fictional media including games, anime, radio, and manga into a compelling whole at the 2002–2003 CESA Awards.

The games' soundtrack, titled .hack//Game Music Perfect Collection, was released as a double album in Japan on April 23, 2003.{{cite web | author=Gann, Patrick | title=.hack//Game Music Perfect Collection | publisher=RPGFan | url=http://www.rpgfan.com/soundtracks/hack-gmpc/index.html | access-date=2010-08-24 | archive-url=https://web.archive.org/web/20100818183049/http://www.rpgfan.com/soundtracks/hack-gmpc/index.html | archive-date=August 18, 2010 | url-status=live | df=mdy-all }} It features 68 compositions by Chikayo Fukuda, Seizo Nakata, and Norikatsu Fukuda. A special edition of this soundtrack includes a third disc featuring sound effects and clips used in the games. The album was released with fewer tracks in North America as .hack//Game Music Best Collection.{{cite web | author=Gann, Patrick | title=.hack//Game Music Best Collection | publisher=RPGFan | url=http://www.rpgfan.com/soundtracks/hack-gmbc/index.html | access-date=2010-08-24 | archive-url=https://web.archive.org/web/20100825191353/http://www.rpgfan.com/soundtracks/hack-gmbc/index.html | archive-date=August 25, 2010 | url-status=live | df=mdy-all }} Patrick Gann of RPGFan wrote that the second disc, which contains music for cutscenes and special events, was stronger than the first disc's generic town and battle themes. He called the soundtrack "techno meets opera", singled out the volume intro tracks for particular praise. Gann noted that the North American release functions as a "Best of" album, but felt that "a lot of solid music [is] missing" in this release. Other reviewers were less enthusiastic; Paul Koehler of RPGamer called the music "particularly bland" and IGN's Dunham lamented that the second installment did not introduce many new pieces.{{cite web | author=Koehler, Paul | title=A Brief Glimpse of "The World" | publisher=RPGamer | url=http://www.rpgamer.com/games/hack/hack/reviews/hackstrev1.html | access-date=2010-08-24 | archive-url=https://web.archive.org/web/20100118004314/http://www.rpgamer.com/games/hack/hack/reviews/hackstrev1.html | archive-date=January 18, 2010 | url-status=dead | df=mdy-all }} However, he concluded that "the melodious piano and oboe themes were still brawny enough to convince us that we needed to buy the soundtrack sometime in the near future".

.hack//frägment is a multiplayer online game based on the fictional MMORPG, The World. It was released only in Japan on November 23, 2005 and online service ended on January 18, 2007, after being extended two months because of its popularity.{{cite web | date=2006-11-22 | script-title=ja:【重要】サービス終了のお知らせ | publisher=Bandai | url=http://www.hack.channel.or.jp/fragment/support/news/1122_news1.html | access-date=2010-12-12 | language=ja | archive-url=https://web.archive.org/web/20070117124843/http://www.hack.channel.or.jp/fragment/support/news/1122_news1.html | archive-date=2007-01-17}} Famitsu Weekly gave .hack//frägment a cumulative score of 29 out of 40 over four reviews, much like its reviews of the main series.{{cite web|url=http://www.gamestats.com/objects/757/757459/ |archive-url=https://archive.today/20120904112703/http://www.gamestats.com/objects/757/757459/ |url-status=dead |archive-date=September 4, 2012 |title=.hack//Fragment |work=GameStats |access-date=2010-12-12 }} The game was never released outside of Japan because it was only intended for a Japanese audience. The game uses a modified version of the engine used in the .hack video game series and thus its gameplay differs from those games in a few ways. Players explore areas and fight monsters in real time but the game does not pause when the menu is opened. Due to this change it is now possible to assign items, messages and skills to hotkeys like in many other online games. Players may still use the skill "Data Drain" to weaken monsters and collect rare items.{{cite video |title=.hack//fragment PV |url=http://www.hack.channel.or.jp/fragment/str.html |format=asx |language=ja |publisher=Bandai |access-date=2010-07-02 |archive-url=https://web.archive.org/web/20100331094632/http://www.hack.channel.or.jp/fragment/str.html |archive-date=March 31, 2010 |url-status=dead |df=mdy-all }} The user interface and control scheme are otherwise mostly unchanged.

Players may create their characters based on a number of preset body shapes and color schemes and may choose a class (such as Wavemaster or Twin Blade), character name and bonus stat points. In online mode, players may enter a lobby and search for a maximum of two other players to join them on an adventure.{{cite web | date=2005-06-29 | title=.hack Goes Online | website=IGN | url=http://ps2.ign.com/articles/629/629887p1.html | access-date=2010-07-02 | archive-url=https://web.archive.org/web/20100501172621/http://ps2.ign.com/articles/629/629887p1.html | archive-date=May 1, 2010 | url-status=live | df=mdy-all }} The game includes an expanded communication interface that allows players to chat, send e-mail, post to an in-game Bulletin Board System, and receive server news updates.{{cite web | title=.hack//fragment Online 4 | publisher=Bandai | url=http://www.hack.channel.or.jp/fragment/online04.html | access-date=2010-07-02 | language=ja | archive-url=https://web.archive.org/web/20110716233805/http://www.hack.channel.or.jp/fragment/online04.html | archive-date=July 16, 2011 | url-status=dead | df=mdy-all }} It is possible to establish ad hoc chat rooms separate from the public-access ones. Guilds are permanent, exclusive chat rooms for members, and can also be used to set up a storefront to sell items to online players.

In offline mode, players may use the same character that they use for online mode, and any skills, items and levels they gain will carry over into online mode. Players may invite or create characters from the .hack games, .hack//Sign, and .hack//Legend of the Twilight into their party. The "story mode" of .hack//frägment is similar to that of the .hack games, though it does not feature any of the antagonists from the original games, and the scenario is an entirely non-canon what-if story.{{Cite book |title=『.hack』手帳 2018 |publisher=Bandai Namco Entertainment |year=2018 |location=Japan |pages=179 |language=ja}}

Players may also install a companion program on their PC called "Area Server", which allows them to create fields and dungeons for players to visit online. As players clear fields and dungeons on a user's Area Server, the Area Server gains experience points and levels. Once the server reaches a certain level, it is possible for custom areas to become "corrupted", much like in the events of the .hack games. Players can visit a corrupted area by breaking into it with virus cores obtained from using the Data Drain skill on enemies, and can defeat a data bug boss enemy at the bottom of the corrupted dungeon.{{cite web | title=.hack//fragment Online 3 | publisher=Bandai | url=http://www.hack.channel.or.jp/fragment/online03.html | access-date=2010-07-02 | language=ja | archive-url=https://web.archive.org/web/20110716233812/http://www.hack.channel.or.jp/fragment/online03.html | archive-date=July 16, 2011 | url-status=dead | df=mdy-all }} Once the boss monster has been defeated, the area corruption is cleared.

Since the game's official online service was closed in 2007, a private server has been created by fans of the game,{{Cite web |title=Home // Netslum // .hack//fragment private server |url=https://fragment.dothackers.org/ |access-date=2022-03-28 |website=fragment.dothackers.org}} along with a fan translation into English.{{cite web |title=tellipatch public releases - Netslum BBS |url=https://bbs.dothackers.org/viewtopic.php?t=80}}
