Last year, BlizzCon attendees received some codes pertaining towards the beta testing of a future Blizzard title. Well, if you were one of the many attendees of that very BlizzCon, now is the time to use your code at the BlizzCon website.
The page redirects to a sign-up page on the World of Warcraft main site, perhaps implying that this future title is related to the MMO. Then again, it’s Blizzard, it could be anything. The website doesn’t point out what game the code will give the user access to but it’s definitely a future Blizzard title which should be a very good game no matter what it is. If you didn’t get to experience BlizzCon last year, then you can always get tickets for BlizzCon this year happening in August.
