OPEN BETA TESTING OF STARCRAFT ® II IN MAINLAND CHINA STARTS ON

MARCH 29, 2011

SHANGHAI, China — March 18, 2011 — Blizzard Entertainment, Inc. and NetEase.com, Inc. (NASDAQ: NTES) announced today that open beta testing for StarCraft® II in mainland China will begin on March 29, 2011. During the open beta test, players will be able to access the multiplayer modes of StarCraft II for free. Players interested in participating can now visit the official Battle.net® website (http://www.battlenet.com.cn), log in to an existing Battle.net account or create a new one, and download the game client in advance.

Following the end of the open beta test period, StarCraft II will be launched commercially in China, at which time players will be able to purchase game time in 30-day increments for a suggested retail price of RMB20, granting access to both multiplayer play and the epic single-player campaign. The commercial launch date for StarCraft II will be announced in the near future.

“We’re excited that players across mainland China will soon be able to experience the intense strategic gameplay and cinematic storytelling of StarCraft II,” said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. “We’ve been continuing to balance and make improvements to the game since its global release last July, and we think Chinese players will agree that StarCraft II has been worth the wait.”

William Ding, chief executive officer of NetEase said, “The original StarCraft is considered to be one of the classic real-time strategy games, which are highly popular among Chinese players, and we believe that StarCraft II will bring even more exciting competitive action to the Chinese gaming community. We are currently focusing all of our efforts on the final phase of preparation for the launch of the open beta, and we look forward to welcoming Chinese players into the game and onto Battle.net soon.”

StarCraft II is the sequel to Blizzard Entertainment’s 1998 blockbuster hit StarCraft, which has been hailed by players and critics worldwide as one of the top real-time strategy games of all time. Sporting a vibrant 3D-graphics engine, StarCraft II once again centers on the clash between the protoss, terrans, and zerg, with each side deploying legions of veteran, upgraded, and new unit types. StarCraft II also features a powerful map editor that allows players to create and share custom maps. Unparalleled online play for StarCraft II is available through a new version of Battle.net, Blizzard Entertainment’s world-renowned gaming service. Battle.net has been redesigned from the ground up to be the premier online gaming destination for players of Blizzard games, with several enhancements and new features, such as voice communication, leagues and ladders, achievements, stat-tracking, and much more.

The solo campaign for StarCraft II picks up the saga where it left off in StarCraft: Brood War®. The story line chronicles the exploits of marshal-turned-rebel leader Jim Raynor and features both familiar faces and new heroes. Players will be able to tailor the experience, choosing their own mission path and selecting technology and research upgrades to suit their playing style throughout the 29-mission campaign. Several challenge-mode mini-games are included, with focused goals designed to ease players into the basics of multiplayer strategies.

StarCraft II was released simultaneously in North America, Europe, South Korea, Australia, New Zealand, Russia, Brazil, Chile, Argentina, Singapore, Indonesia, Malaysia, Thailand, the Philippines, and the regions of Taiwan, Hong Kong, and Macau on July 27, 2010. Following its release, StarCraft II sold more than 1.5 million copies in its first 48 hours of availability, making it the fastest-selling strategy game of all time. The game has gone on to sell more than 4.5 million copies worldwide.*
