Xiah, a free to play martial arts themed MMO, is the creation of Korea's Taewool. The game blends RPG content with the feel of console action games. Detailed graphics are a highlight, as are the creature AI - a monster may attack you, then return with reinforcements if you get away.
Leveling is accomplished via the usual means, and to assist you, weapons can be upgraded with five elemental types. Once you level up, the game's rebirth system allows you to start over with experiences intact as well as special bonuses, extending the game's life.
PvP is featured in the form of guild sieges as well as solo modes. Xia is free to play, with an item shop, and Xiah: Rebirth, a free expansion to the game, was announced shortly after the North American release.
