The Unity engine and ecosystem gives developers a world class technology platform from which they can build games that work seamlessly across multiple platforms quickly and effectively.

The Facebook SDK for Unity complements Unity Technologies' cross-platform support, providing a pure-Unity write-once, run-everywhere experience across the key gaming platforms of WebGL, Unity Web Player, Android and iOS. By maintaining a single codebase, you'll be able to deploy socially integrated gaming experiences to your players, regardless of platform.

The Facebook SDK for Unity provides a comprehensive collection of Facebook's social features, giving players of your Unity game the ability to share content with their friends and allowing you to create a personal, social gaming experience. In addition to providing a base set of features that are invoked consistently across platforms, the SDK also offers support for Facebook features that are unique to a particular platform (e.g. payments on the Web or App Invites on mobile). This will allow you to keep your code clean, using a simple, consistent model for everything your game can do on Facebook.
