Six new trailers have been released, showing over nine minutes of the second expansion to the most popular MMO ever, Blizzard's World of Warcraft.

World of Warcraft: Wrath of The Lich King will allow you to explore Northrend, raise your level to 80, and obtain new items.

In addition, Wrath of the Lich King will introduce the death knight hero class to World of Warcraft. Once certain criteria are met, players will be able to create a new death knight character, which will start at a high level. Furthermore, player-vs.-player battles will reach a new level of intensity with the addition of siege weapons and destructible buildings, not to mention a new battleground.

There will also be an abundance of new quests, dungeons, monsters, items, and recipes - as well as a new profession, "inscription" - for players to try out. The expansion will include some additional character-customization options for players as well.

Unfortunately we cannot confirm if Wrath of the Lich King will be released this year, but here's hoping! In the meantime, have a look at the trailers:
