Good news for the StarCraft faithful, as the StarCraft II: Heart of the Swarm beta begins today. Blizzard announced a few weeks ago the beta would be beginning soon, and it has delivered. The studio has sent out the first wave of invites to the multiplayer-only beta, so be sure to check your email to see if you made it in. More invites will be going out before long, although the studio notes that opting in on your Battle.net account does not guarantee a selection. Certain fansites will also be able to hand out keys, which Blizzard will reveal details on those sites later on. The Heart of the Swarm beta is not under an NDA, so anyone who made it in is free to talk about it. There will undoubtedly be live streams and screenshots galore for you to check out during the beta, so everyone can at least see the new units that way. There is no set end date for the HotS beta, but Blizzard will let all the particpants know when it is near.
