all about .hack//G.U :
hack//G.U. simulates a massively multiplayer online role-playing game; players assume the role of a participant in a fictional game called The World. While in The World, the player controls the on-screen player character, Haseo, from a third-person person perspective (with optional first-person mode). The player may control the camera using the game controller's right analog stick. Within the fictional game, players explore monster-infested fields and dungeons as well as "Root Towns" that are free of combat. They also can "log-off" from the game and return to a computer desktop interface which includes in-game e-mail, news, andmessage boards, as well as desktop and background music customization options. In Reminisce, an optional card game called "Crimson VS" becomes available. The player may save the game to a memory card both from the desktop and within The World at a Save Shop. After the player completes the game, a Data Flag appears on the save file, which allows the transfer of all aspects of the player character and party members to the next game in the series.
Players can attack monsters in real time. However, the action pauses whenever the menu is opened in order to select magic to cast, items to use, or skills to perform. The player only directly controls Haseo, while the other characters are controlled by artificial intelligence. The player may either provide guidelines ("Free Will", "Rage", "Life", etc.) or issue direct commands (for example, to cast a particular magic at a particular enemy) to the computer-controlled characters. Monsters roam the environments freely or guard treasure chests. Once combat is initiated, via a "surprise attack" or the player being spotted, a wall erects around the combat area to prevent escape. Under certain conditions, the player may execute a "Rengeki" attack via the Skill Trigger menu. These attacks deal greater damage and fill a Morale gauge, which allows the player and his team members to use a combination attack. Certain plot-related fights, called "Avatar battles", use a different interface which incorporates shoot 'em up gameplay elements. After depleting the opponent's health, players must charge up a "Data Drain" to end the battle.
Root Towns are non-combat areas in The World. The player may restock on items, buy equipment, or chat and trade with other "players" of The World. The player may also undertake optional quests and visit guilds. A key feature of all towns is the Chaos Gate. This blue portal is used to travel between towns (called "servers") as well as access the fields and dungeons where battles take place. A password system controls the characteristics of each area. Depending on the characteristics of each word in the three word phrase, the resulting area may have different attributes such as prevalence of monsters or items, among other features.
The main playable character of .hack//G.U. is Haseo, a player of The World whose friend Shino fell into a coma after being attacked by a PK named "Tri-Edge" within the game. As a result, Haseo becomes obsessed with becoming strong enough to defeat Tri-Edge and save Shino—he earns the nickname "Terror of Death" for his relentless hunting of PKs. As an Epitaph PC, Haseo is recruited into the new incarnation of Project G.U., which now handlesdebugging of The World. Yata, who played a key role in the events of .hack under the name Wiseman, leads Project G.U., while other Epitaph PCs including Kuhn and Pi comprise the rest of the group. Haseo's hostile nature attracts the attention of Atoli, a member of the peace-loving Moon Tree guild, who resolves to befriend him. Haseo is also searching for Ovan, Haseo's and Shino's former guildmaster who disappeared during .hack//Roots under mysterious circumstances.Setting
Following the events of .hack//Roots, Haseo has become a ruthless and powerful player. A chance encounter with Ovan leads him to the Hulle Granz Cathedral, where Shino was put into a coma. He encounters and battles "Tri-Edge" but is soundly defeated. Tri-Edge uses a powerful, illegal skill called "Data Drain" on Haseo, which resets his character data to level one. Lacking the strength he once had, Haseo is mistaken for a newbie player by Silabus and Gaspard, who invite him to join their guild, Canard.
.hack//Roots was a TV anime series that serves as a prequel to the video games, depicting Haseo's first experiences playing The World. As part of a larger multimedia franchise, the games have inspired a variety of subsequent novels, manga, and film. A novel series of the same name retells the story of the games with slight modifications, such as depicting Epitaphs as weapons instead of physical Avatars. .hack//G.U.+ serves as a manga adaptation of the game's story. .hack//G.U. Trilogy is a computer animated film adaptation of the games that takes numerous liberties with the story. The games' sequel is .hack//Link, a manga series that takes place three years in the future with a new version of The World.
.hack//G.U. Game Music O.S.T. and .hack//G.U. Game Music O.S.T. 2 are the soundtracks for the .hack//G.U. games. The former contains 62 compositions from Rebirth while the latter contains 58 compositions from Reminisce and Redemption. Both soundtracks come with a third disc with special features, such as game trailers, desktop wallpapers, and voice clips. Chikayo Fukuda composed the music for the series, as well as for the previous set of .hack games. Patrick Gann of RPGFan commended Fukuda's more mature sound, noting a greater emphasis on vocal tracks than before. He praised the use of piano as a key instrument and found this soundtrack to be more memorable overall. Gann also appreciated the wide variety of styles from "silly character themes" and "rock-hard battle themes" to "beautiful piano solos".
