.hack//G.U. is a series of single-player action role-playing games for the PlayStation 2 developed by CyberConnect2 and published by Bandai Namco Entertainment between 2006 and 2007. The series contains three games: .hack//G.U. Vol. 1//Rebirth .hack//G.U. Vol. 2//Reminisce and .hack//G.U. Vol. 3//Redemption. As in the previous .hack games .hack//G.U. simulates a massively multiplayer online role-playing game (MMORPG) called The World—the player controls a character who plays the fictional online game. They were directed by Hiroshi Matsuyama who aimed to address criticisms of the previous series. Its narrative by Tatsuya Hamazaki was written concurrently with .hack//Roots an anime set before the events of the games.
