On their developers blog, Facebook has announced that they are launching a new cross-platform software development kit (SDK) that will allow easier integration of their social sites identity and features for developers creating games using the Unity development platform.
Today, at Unity's developer conference, Unite, in Vancouver, BC, we launched a new cross-platform SDK that makes it faster and easier to integrate your Unity game with Facebook. Whether you're building on iOS, Android, web, or all three, the SDK lets you continue to write in C# and provide social game experiences to all your players, regardless of the platform they play on.
They also stated that more than 260 million people are playing games on Facebook each month, and that number continues to rise. Also noted in the blog was that "The number of active Facebook users with Unity installed more than tripled in the first half of 2013, and today more than 90 million monthly active users have Unity installed on the web."
