On Thursday at Tokyo Game Show, Bandai Namco games announced that .hack//Link, the final chapter of the long-running .hack media franchise, will include an all new, fully CG anime along with the PSP game due to come out in February 2010. The .hack series started in 2002 and was designed as a multimedia blitz, with almost all of its installments available in manga, anime, and video game form, so this is nothing new to the series.
The series, which includes .hack//Sign, .hack//Legend of the Twilight, and .hack//Liminality, takes place in a fictional online role-playing game known as The World, and is notable for rarely ever depicting the players, just their game avatars. Most of the .hack series have been distributed in the United States by Bandai Entertainment.
