Battle.net and Facebook Integration Announced Blizzard Entertainment’s Next-Generation Online Gaming Platform Will Integrate with Facebook to Enhance Social Gaming Experience

IRVINE, Calif., May 05, 2010 — Blizzard Entertainment, Inc. announced today that its Battle.net gaming service will integrate with Facebook, linking the world’s premier online gaming platform with the world’s most popular social platform. The first step in the integration will enable StarCraft II: Wings of Liberty players to quickly add Blizzard gamers who are friends on Facebook to their Battle.net friend lists, facilitating their social gaming experience on the service.

“We’re pleased to be working with Facebook to integrate their platform with Battle.net to enhance the social-entertainment experience for our players,” said Paul Sams, chief operating officer of Blizzard Entertainment. “This new functionality will make it easier than ever to connect with friends on Battle.net and play StarCraft II and future Blizzard Entertainment games together.”

The new Facebook functionality in Battle.net will be tested in the near future via the ongoing StarCraft II: Wings of Liberty beta test and will be available to all StarCraft II players when the game ships later this year. Information about other Facebook-related features on Battle.net will be announced at a later date.
