StarCraft II: Wings of Liberty launched on July 27, 2010, and sold through more than 1 million copies in its first 24 hours of availability and more than 3 million in its first month, making it the fastest-selling strategy game of all time. Alongside the launch of StarCraft II, Blizzard released a brand-new version of its acclaimed online gaming service, Battle.net, which has been redesigned from the ground up to be the premier online gaming destination for Blizzard gamers, with several enhancements and new features, such as voice communication, cloud file storage, leagues and ladders, achievements, stat-tracking, and more.
