The official Korean website for Maplestory 2 recently revealed 4 class concept pictures featuring the Priest, Berserker, Wizard and Knight classes. NSquare (the joint team between Nexon and NCSoft) has done a great job keeping the highly anticipated game shrouded in mystery.
All we know about the game at this point is that the game’s background story will be taking place in prior to the Maplestory story, that the game will be 3D and will feature many familiar monsters from Maplestory. Maplestory 2 is planned to enter closed beta (in koera) some time next year.
