.hack (pronounced "dot-hack") is a Japanese multimedia franchise that encompasses two projects; Project .hack and .hack Conglomerate. Both projects were primarily created/developed by CyberConnect2, and published by Bandai. The series is mainly followed through the anime and video game installations, and has been adapted through manga, novels and other related media.


fictional chronology

The series takes place mainly within The World, a fictional MMORPG published and maintained by the also fictional CyberConnect Corporation, known as the CC Corporation. Players interact with The World using virtual reality headsets called HMDs (Head-mounted display) and a gamepad. It is the creation of German programmer Harald Hoerwick, who created the first version, "Fragment", to help create his virtual daughter, Aura.

The World consists of a cluster of servers distributed around the world. When players log in, they materialize in the Root Town of the server they last used. Each server in The World has its own unique Root Town. They are the starting and ending point of any gaming session. In order to properly log out of the game, the player must be in a Root Town. Each Root Town has a Chaos Gate, a large revolving ring used to transport players to areas or other servers. To transport to an Area, a series of three keywords must be entered. These keywords determine such parameters as difficulty, terrain, and weather, amongst other habitat. Most keyword combinations result in a field and/or a dungeon.

Before the series began, Pluto's Kiss, a virus, caused a simultaneous crash of all computers and network control systems on the Internet that did not run on the ALTIMIT OS, which subsequently became the dominant operating system worldwide. The Twilight Incident, also known as Pluto Again, and the Second Network Crisis is the series of disasters depicted in the .hack//Games. It involves the massive blackout and system shutdown at Yokohama, which results in multiple car accidents, fires throughout the city, various other system malfunctions in other parts of Japan, and various players of The World ending up comatose. It is caused by the glitching Morganna System, though it is eventually resolved with the full awakening of Aura. Kazushi Watarai is held responsible, despite being hospitalized for the majority of the incident.[1]

The World R:2[edit]

Due to a fire in CC Corporation headquarters a year following .hack//Legend of the Twilight, CC Corporation had made a new version of the game called The World Revision:2 or simply as "The World R:2". The World R:2 offers new locations and old ones that are hidden within the game, these locations are commonly known as the lost grounds. There are many character classes, new and old. PKing (player killing) has become very popular in The World R:2 and due to this uprising, a guild called "Moon Tree" has been created against PKing. The leader of Moon Tree, Zelkova, is an expert hacker and created a place for hackers called "Net Slums".

The World R:X[edit]

The World Revision:X (or simply as "The World R:X") is a new portable version of The World created three years after the world R:2 was made. The World '​s fictional in-game setting is set a thousand years after the original version.
