In order for game developers to continue expanding the realm of the game, they must literally expand the game itself, and this is done through issuing new chapters. These chapters, while useless on their own, help to broaden the World of Warcraft when they are purchased and installed in conjunction with the original game.

World of Warcraft: Wrath of the Lich King is set to be the second expansion for the game, and purchasing the package allows gamers to buy death knight capabilities. The death knight class is a classic class first introduced in the original World of Warcraft games, and it is the only new hero class planned for the new expansion.

More than just another secondary class, buying death knight capabilities means opening a whole new world. Expect more than a new class but also new dungeons, weapons, spells and quest lines among other game content.

Death knights use a rune system instead of the familiar way spells are currently used in game. Death knights are expected to be useful in group situations like in dungeons and during raids, and offer a new learning curve even for the most experienced WoW players.

While players may think twice before investing additional money to buy death night capabilities in the game, World of Warcraft: Wrath of the Lich King and all it offers is definitely worth the money, and gamers shouldn't hesitate.
