Age of Conan: Unchained (formerly known as Age of Conan: Hyborian Adventures) is a fantasy-themed massively multiplayer online role-playing game (MMORPG) developed by a Norwegian computer video game developer company, Funcom, and is published by Eidos Interactive for Microsoft Windows.
The game's pre-release occurred on May 17, 2008, available to those who had pre-ordered the game and registered for early access; the full release and launch of the game was May 20, 2008 in Northern America, and May 23, 2008 for Europe. Although originally announced as being available for the Xbox 360, the console version has now been cancelled. Originally, in order to continuously play Hyborian Adventures, users were required to pay a monthly subscription fee.
In May 2011 Funcom announced that a free-to-play (F2P) option would become available later in the year, although customers would still have the option to subscribe. The free version of the game became available in June 2011, offering limited access to game content, while subscribers received 'premium' access to all available game content. A microtransaction system was introduced in summer 2011 to enable players to purchase in-game items via Funcom Points.
Hyborian Adventures is the first installment in the planned Age of Conan series. Age of Conan itself takes place within the continent of the Hyborian kingdoms, a year after the events depicted in Robert E. Howard's Conan novel, The Hour of the Dragon. Hyborian Adventures' release celebrated the 76th anniversary of the Conan franchise.
