Revealed in March this year, developer Star Ducks Studio finally put out a game demo for Wild Buster over at G*Star 2012, although it is limited to only the B2B hall.
A sci-fi isometric MMORPG, similar to Torhclight II and Diablo III, there are no classes here, but characters.
Each will have their own skill trees, and the fun only really begins when the “max level” is hit. I am expecting a Dota-styled map in the near future as well, seeing that there will be 2 opposing factions for PvP.
