Perfect World Entertainment announced today that Jade Dynasty, the English-based version of Zhu Xian, one of China's most popular Free-To-Play games, will be celebrating its one year anniversary on June 16th. Since the game launched in 2009, Jade Dynasty players have spent more than 2,000 years in the game using the unique Invigorate combat aid. The Invigorate combat aid is a feature which allows players to bypass the typical grind associated with most typical MMOs. In celebration of Jade Dynasty's one year anniversary, players will enjoy double EXP for 120 consecutive hours starting on June 16th - 20th. As an additional incentive for players to log on during Jade Dynasty's anniversary week, players who log a total of 100 cumulative hours in-game (from June 14th - 20th) will be rewarded with a special gift.
