Beijing China (October 23, 2008) - Perfect World Co., Ltd. (NASDAQ: PWRD) ("Perfect World" or the "Company"), a leading online game developer and operator in China, today announced the launch of "Horseback Fighters," the latest expansion pack for "Chi Bi," the Company's 3D massively multiplayer online role playing game ("MMORPG") based on the Three Kingdoms period in Chinese history.

"Chi Bi" features aesthetic graphic design and distinct elements of traditional Chinese culture. Moreover, the game's special features, such as the "18 Legendary Weapons System" and the "Battle of the Three Kingdoms System," have made "Chi Bi" a popular game among online game players.

This latest expansion pack introduces a large number of updates, including new battlefields, higher levels for in-game characters and new maps, such as "Tranquil Iceland," "Secluded Garden Valley," "Mysterious Lolan Desert" and "Enchanting Flowering Forest." One of the most unique new features is a "Horseback Fighting System," which allows gamers to experience fast-paced and exciting battles on horseback. In addition, two new weapons, "Halberd" and "Folding Fan," have been added to the "18 Legendary Weapons System".

Mr. Michael Chi, Chairman and Chief Executive Officer of Perfect World, commented, "As our first 3D MMORPG based on Chinese history, 'Chi Bi' has been developing well since its launch. I believe the new content of this expansion pack will bring new and exciting experiences to online game players."
