Blizzard announced today that one of its most anticipated titles, previously in closed beta, would become a free Open Beta Weekend for all users with a Battle.net account beginning April 20. All you have to do is download the client here and starting 12:01 PDT, you will have access to five heroic classes up to level 13. This open beta will act as a stress test for the servers leading up to the May 15 release date for the game.

What steps do I need to take?
