The closed beta test for StarCraft II: Legacy of the Void kicked off earlier this week, and you might very well be in without realizing it.

At this stage of the beta, Blizzard won't be sending out beta keys. Instead, it says it'll directly provide access to Battle.net accounts, something which won't necessarily provide you with any indication that you're in.

Luckily, there's an easy way to check. In the Battle.net desktop app, simply click on the region-selection drop-down menu (located just above the Play button) and look to see if you have anything listed under an "In Development" section. If so, your account has been given the go-ahead to start putting Legacy of the Void through its paces.

If you aren't in, you should make sure that you've indicated that you're interested in StarCraft betas on your Battle.net profile (something you can also do for Blizzard's other franchises). Beyond that, there's little you can do to help your chances of getting in--testers are selected based on things like systems specs, recent StarCraft II activity, and luck.

In the future, there will be giveaways that provide access. Alternatively, if you bought a ticket to BlizzCon (the event or a Virtual Ticket) or the StarCraft II WCS 2014 Global Finals, you'll be getting "priority access" before people who have simply indicated they're interested in the beta. Because beta keys aren't being distributed right now, only the account that bought tickets to any of the aforementioned events will get access, even if you bought multiple tickets.

The lack of beta keys also means one other thing: If you're notified about a way to receive one, it's a scam.

There's no time table for how long the beta will run for. Even if you don't get in, those who do have access are free to stream and talk about the experience, so there won't be any shortage of details to come in the weeks and months ahead.
