Perfect World Entertainment has announced that the next expansion for its martial arts MMO, Jade Dynasty, will be arriving on August 25th. Called 'Vengeance', the expansion will feature two new playable factions and a territory war system that will pit player alliances against one another.

Other features include:

• New Factions - Choose between two new Athan factions including the Celan, known for their ability to manipulate foes and support allies using their music notes of the Immortals, or the Rayan, feared as deadly assassins, even among their own allies.
• Territory Wars System - For the first time, experience true, ongoing alliance versus alliance warfare, which will vary from server to server.
• PvE Daily Events - Participate in new PvE daily events designed to have much higher rewards.
• Party System - Communicate across realms to similar level players for easier partying.
• Unique Auction House - Bid on high-level or one-of-a-kind items on the auction house, which will award items to players for having the lowest unique bid versus the highest.
