Initial testing of Heroes of the Storm is now underway, an invitation-only technical alpha for Blizzard's upcoming team brawler (thanks Dirwulf via Joystiq). This forum thread addresses requests for access, saying no keys are available right now, and offering steps to avoid phishing attempts based on the test. According to the latest blue Blizzard post on the topic: "We're eager to get as many people as possible into the Nexus as soon as possible, but we don't have any news on that front at the moment. As soon as we do, though, we'll be sure to announce it and let everyone know."
