Blizzard - Single Launcher for All Blizzard Titles
Blizzard has announced the release of the Battle.net App. In the coming months each game's launcher will update to the Battle.net App, or you can opt for now. It'll likely be required of every new game they release in the future.
In the months ahead, the game launchers for World of Warcraft, StarCraft II, and Diablo III will be automatically updated to our new desktop app for Battle.net, designed to improve the launcher experience and streamline your ability to play Blizzard games—but if you're interested in upgrading now, you can!
