When Apple launched its App Store in 2008, Unity quickly added support for the iPhone. It included a Networking Layer for developers to create multiplayer games based on the User Datagram Protocol, offering Network Address Translation, State Synchronization, and Remote Procedure Calls. The release also added features whereby developers could collaborate more easily. The release included an optimized terrain engine for detailed 3D environments, real-time dynamic shadows, directional lights and spotlights, video playback, and other features. Unity 2.0 launched in 2007 with approximately 50 new features. Unity was initially released for Mac OS X, later adding support for Microsoft Windows and Web browsers. The next year, Unity was named runner-up in the Best Use of Mac OS X Graphics category in Apple Inc.'s Apple Design Awards. The Unity game engine launched in 2005, aiming to "democratize" game development by making it accessible to more developers.
