One exciting new feature in Wrath of the Lich King is that all raid content will be available as either a 10- or 25-person dungeon with completely independent progression paths. Both the 10- and 25-person versions will be the same dungeon; the look, layout, and design of the dungeon will remain the same. However, each will be adjusted, tuned, and balanced for its respective player size.

In Wrath of the Lich King, players can expect both 10- and 25-person raid progression paths to get increasingly difficult as they adventure to their final battle with Arthas. This new gameplay mechanic will allow more players to enjoy the raid content of Wrath of the Lich King in their preferred play style. Because it takes more effort to get 25 people together than it does for 10, players who participate in the 25-person raid progression path will receive higher quality and more loot than those who play the 10-person versions.

The quest designers are hard at work to make sure that the road to level 80 will be paved with quests unlike anything you’ve ever seen before. The Burning Crusade innovated with bombing runs and daily quests, and Wrath of the Lich King will continue this trend with still more unique and varied adventures to undertake.

Just one example of the new mechanics you can expect from the expansion is the new vehicle-based content, which puts an interesting spin on some of the concepts originally developed for PvP siege gameplay. Certain types of vehicles and mounts can now carry passengers, making it possible for players to, for example, break a prisoner out of a tightly guarded compound by attempting a daring escape on horseback. While the NPC steers the horse, the player lobs explosives at a pack of pursuing worgen. In another quest, the roles are reversed as the player takes to the skies in a flying machine to track down and rescue survivors of a catastrophic event. Even beyond the ability for vehicles to hold passengers, Wrath of the Lich King introduces an aerial combat system that will add a new dimension to gameplay.
