Microsoft acquired SyntaxTree, the developers of the UnityVS plugin for Visual Studio. UnityVS enables Unity developers to take advantage of the productivity of Visual Studio to author, browse and debug the code for their Unity applications. As of 2013, dozens of the biggest names in game development rely on Visual Studio and the UnityVS plugin. With this acquisition, Microsoft has the opportunity to integrate this support for Unity even more deeply into Visual Studio, and to continue to push forward Visual Studio's support for game developers.
