The next chapter for Perfect World Intenationa: New Horizons is now available in the Free-to-play universe. Titled Chill of Luneska, the latest expansion will offer new quest lines and plenty more guild-based events to help enhance the popular MMO. The guild-modes will help build upon the PvP already available in game by adding Territory Resource War, a weekly event that will deliver opportunities for players to interact with one another. It isn't about a one-time battle anymore but, rather, a continuous battle for resources and riches.
Some screenshots are available and more can be found at the PWI main website, including where to download the expansion for your current client.
