The next big expansion to Blizzard's massively popular massively multiplayer online game World of Warcraft is, officially, in beta and ready to be tested by you. Did you get an invitation for the Cataclysm beta? Better check your Battle.net account.
Blizzard says it has begun issuing invites to WoW players from around the world who opted in to the Cataclysm beta test via Battle.net. You could be customizing your Worgen or Goblin and journeying to new, previously undiscovered areas of Azeroth within hours, well on your way to seeing what a level cap of 85 looks like.
How do you know if you've been selected? Check the email account tied to your Battle.net account or, better yet, just log in to Battle.net to find out. Your World of Warcraft profile should be flagged by Blizzard.
More details at the official World of Warcraft site. Have fun Cataclysming!
