The cinematic trailer was unveiled at this year's gamescom expo.
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.
Also on offer is a Digital Deluxe edition for £39.99 / $59.99, priced £10 / $20 more than the standard version available digitally.
Mists of Pandaria will be released on September 25 worldwide.
