What are the features of the new expansion?

Wrath of the Lich King builds on the rich foundation established in World of Warcraft and The Burning Crusade, providing a wealth of new content for players to explore. The harsh, forbidding continent of Northrend, home of the Lich King and his undead minions, will be uncovered on the world map, and to contend with the new challenges found there, players will be able to advance to level 80, acquiring potent new abilities and talents along the way.

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. We'll be going into more detail on all of these features in the months ahead.
