Now, the developer is hard at work on the Korean import's first expansion called Assault on Balaurea. Previously known as Update 2.0, Assault on Balaurea is different from other expansions on the market simply due to the fact that it's completely free. It is a huge content update that will be available for digital download on September 7th. A new retail version of the game that includes the new expansion content, as well as an exclusive in-game pet (more on that later), will also be available for purchase in North America on September 7th and in Europe on September 10th."
