That's right- the Heart of the Swarm beta has started!

Quote from Blizzard:

The Heart of the Swarm beta test has begun! This multiplayer-only test will initially be limited to a select group of pro-gamers, members of the press, Arcade contest winners, and shoutcasters. Beta test participants are not under NDA, so you’re likely going to see live streams of matches, screenshots, and casts of impromptu Heart of the Swarm throwdowns starting . . . mmm, NOW!

We will soon be inviting other players to participate in the beta, so be sure you’ve opted in by clicking on the "Beta Profile Settings" under the Account Management section of your Battle.net account (or just click here). Signing up from a Battle.net account that’s actively playing StarCraft II will help your chances of being selected. Note that opting in doesn't guarantee beta access.

As always, keep an eye out for suspicious emails. If you think you've been invited to the beta, go to your battlenet account and check there (don't click email links).

And of course, you can except coverage of the beta from sc2mapster! Join the discussion here!
