The .hack// Games Tetralogy are a set of four Action RPG games released for PlayStation 2. The collection of games are sometimes referred to as a Tetralogy or Quadrilogy. Fans also use the abbreviation "IMOQ," taking the first letter in each consecutive game's western title in order (Infection, Mutation, Outbreak, Quarantine). Each game came packaged with a bonus DVD of the OVA .hack//Liminality, which shows offline events occurring concurrent to the events in-game. The games are set in the "first season" of the .hack series, taking place after SIGN and ZERO. Several other media retell the events of the games, including .hack//Another Birth, .hack//XXXX, New Novelization [.hack] and .hack//Link.

The four games take place in a "game within a game," in this case the fictitious MMORPG called 「The World」. The story explores how events in that occur online in「The World」 have an impact on the offline world in-fiction. Players take the role of Kite, a new player who acquires abilities that surpass the system as he seek the answers to various mysteries that are tied to the game. The core gameplay simulates a Desktop where players can read e-mails, chat on forums, and play 「The World」. While playing The World, players can form parties with other players, delve dungeons for treasure, and participate in events. The BBS, Email and News on the desktop update over time as the player progresses in game. The BBS and email can help players access more areas as the story moves forward.

The games were developed by CyberConnect2, Co., Ltd. and Published by Bandai. Initially released in Japan between June 20, 2002 and April 10, 2003, the games went on to be translated for North America, Korea, and Europe and Australia in 2002-2004. The Games Tetralogy titles are included in the "First Season" of the .hack series, also known as "Project .hack." Project .hack was designed to be a multimedia project, with manga and anime released before the games the introduce audiences to the setting and establish the overarching mystery of the storyline.
