The latest and greatest update to Blizzard Entertainment’s enormous (and massively) multiplayer online RPG, World of Warcraft: Cataclysm, recently went live to bring your game up to version 4.3.

New to World of Warcraft with this patch adds a whole new raid and new dungeons, a new quest line, new armour sets, a Raid Finder tool, as well as features known as ‘Armour Transmogrification’ and ‘Void Storage.’

I hope those mean something to World of Warcraft players, because it’s all Orc to me.

The full patch notes for 4.3 can be found over here.

Get excited for patch 4.3 for Cataclysm below with a newly released trailer, and also be sure to watch ten minutes of gameplay from the three new dungeons in the Hour of Twilight storyline:

Here’s some story set up for ‘Hour of Twilight’:

“In the wake of the Cataclysm, Azeroth’s champions rose up to thwart the forces of the maddened black Dragon Aspect, Deathwing. Thus far the world’s defenders have shattered the power base of the Twilight’s Hammer cult and defeated the raging elemental lords Al’Akir and Ragnaros. Yet despite these victories, as long as Deathwing is free to pursue his twisted goals, Azeroth will remain under threat.

“No one is more aware of this fact than the great Dragon Aspects Alexstrasza, Nozdormu, Ysera, and Kalecgos. Together with the wise shaman Thrall, they have devised a plan to vanquish Deathwing with a weapon of his own design: the infamous Dragon Soul.

“In patch 4.3, Thrall and the noble Aspects will call upon the Horde and the Alliance to help them retrieve the artifact—no longer in existence—from the distant past. Those brave enough to face the challenge will embark on a perilous journey from Azeroth’s apocalyptic End Time to the Dragon Soul’s point of origin during the catastrophic War of the Ancients. If the heroes succeed, an even more harrowing battle awaits them in the present…”
