The live European launch kicks off on Monday, September 24 at 9.30pm (GMT), an hour and a half before the game is available in store.
The live stream will capture launch events from Paris, Moscow, Milan, Madrid, London, Stockholm and Cologne.
Blizzard's Mike Morhaime, Greg Street, Chris Metzen, Tom Chilton and Cory Stockton will attend the events, offering a behind-the-scenes look at the expansion and explaining some of its new features.
A live orchestra will also be on hand to perform music from the game, as well as Manao - Drums of China.
The fourth expansion to the popular massively-multiplayer game adds a new playable race named the Pandaren with its own starting zones and quests, the monk character class, a new continent with a level cap of 90, challenge modes and a pet battle system.
Available through both retail and online from Battle.net, players can pre-order and download the expansion ahead of release, ready to play as soon as the expansion launches.
Mists of Pandaria will be released on September 25 worldwide.
