GREE Korea just launched their first Closed Beta Test for Lost in Stars. This game looks like it has a lot of potential for a mobile action MMORPG. The game featured slight similarities between Ragnarok Online 2's graphics and UI. I'm not sure if the Japanese/English version of this game is already out, I would sure love to try it out especially if they have an iOS version. Anyway, the gameplay trailer below is worth checking out if you haven't seen it yet!
