Yes folks, Blizzard has finally announced that the multiplayer beta for StarCraft II: Wings of Liberty has now begun. Unfortunately, this is a closed beta, but if you were lucky enough to get an invite, the downloader is available through Battle.net.

Please note that even though StarCraft II hasn’t been released yet (it is planned for release “in the first half of 2010”), the game is already available for preorder on Amazon.com.
