The time has come. Blizzard has just announced the start of the Heart of the Swarm beta, which will initially be limited to progamers, press, Arcade contest winners, and shoutcasters. There is no NDA however, so prepare for the flood of Heart of the Swarm content coming your way!
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.
The Blizzard post also includes an FAQ about the beta, which you can check out here.
We here at StarCraft: Legacy will be dedicated to brining you all the latest news about the beta as it develops. Check back regularly for updates!
