Special thanks to rezistance12, who pm-ed me on YouTube informing me that the teaser website for Cabal II has been refreshed. Thanks! And yes, the storyline and classes for Cabal II is now added, with the original inhabitants crossing the ocean to a new land, inevitably separated by different beliefs into 2 opposing factions.
For classes, there is nothing new except the addition of a Priest class and the missing Blader class. Hop on to the teaser website for a look! You can also view the debut trailer for Cabal II here.
