Lineage I players who think they've done everything there is to do in the game, hold that thought, because Episode U goes live tomorrow and you won't be bored for a very long time.
The patch notes encompass a very long list of new content as well as updates to old content. There are new zones, bosses, and quests, as well as some new mini-games such as pet racing. The content isn't limited to gameplay, however. Take a look at the new mail system, the many new furniture items, and the new alliance system as well.
The patch has been in testing, and there are still some bugs to be worked out. The patch announcement states "We are still committed to fixing more bugs, but we do not wish to delay the patch any longer," and notes that none of the current bugs are game-breaking.
Take a look at the full patch notes here, and enjoy Episode U!
