The fourth expansion for the wildly popular MMO World of Warcraft is now available in North America, Europe, Australia, and select South American countries.

The expansion chronicles the discovery of a new continent in Azeroth. Players can take on the role of a character of the Pandaren race, fight as the new monk class, and explore the new continent as they level up to the new level cap of 90. The expansion also includes a new type of cooperative PvE trial, challenge modes, and, of course, the new pet battle mini-game.

“Mists of Pandaria takes players back to the roots of World of Warcraft – exploration, discovery, and the epic conflict between the Alliance and the Horde,” said Mike Morhaime, CEO and co-founder of Blizzard Entertainment. “It also contains the widest variety of content that we’ve ever added in an expansion, and we’re excited to be able to share it with players around the world this week in our first truly global launch.”

To celebrate the launch, Blizzard held a massive launch party in cities across Europe, including Paris, Moscow, London, Stockholm, and Milan. The festivities were streamed on YouTube, but if you missed the live-stream a replay of the events can be seen below.
