When it comes to the free-to-play business model, US-based early-adopter Gala-Net has certainly raised a few eyebrows with its light-hearted fantasy MMO Flyff. Also known as Fly For Fun, Flyff has now had its doors open for several years and is showing no signs of slowing down. The game's latest expansion, Rise of the Muran has just gone live, bringing players a whole array of new content and gameplay just in time for Christmas.

The expansion raises the game's level cap to 139 and includes a new third job evolution system, introducing eight new classes to the game. Players can now take on the roles of Templar, Slayer, Harlequin, Crackshooter, Force Master, Seraph, Mentalist, and Arcanist. Also included for players is a new guild housing system, in which high-level guilds can bid on huge shared buildings. As if that wasn't enough, Rise of the Muran opens a new area of the game for exploration -- the lost region of Kaillun. It's here in the safe city of Eillun that a new race of friendly cat-like creatures known as the Muran live. With all the new content to explore, new classes to try out and a brand new achievement system coming in, there's sure to be a lot for Flyff fans to do while wrapped up warmly in their houses this winter.
