TERA's Developer Bluehole Studio Working on Project W and Project EXA
Project W is developed by developers from Aion, TERA and ArcheAge dev. team. It is a next-generation MMORPG that integrates both popular game features and new entertainment trends aiming to provide players with new game experience.
We actually reported the other game Project EXA last month at Nexon Developer Conference 2014. Bluehole Studio representative said that this game combines both social and strategic features and is different from TERA in combat.
