WoW Patch 4.3 'Hour of Twilight' launches today

If you've built up a thick layer of hatred for Deathwing every time his grim visage appears on the login screen for World of Warcraft, your hour of retribution has come. Or rather, your "Hour of Twilight" has come -- that's the name of WoW Patch 4.3, which launches today.

The update, and last major addition for WoW: Cataclysm, adds three new dungeons and a new raid to the title which see your hero traveling through time in an attempt to gather the tools required to take Deathwing down. There are also new, oft-requested features like Armor Transmogrification and Void Storage. Check out the trailer above for a taste of the action, and turn an eye towards WoW Insider for all the juicy patch notes therein.
