Unity is a tool for developing two- and three-dimensional applications and games that runs under the operating systems Windows, Linux and OS X. Unity-based applications run under Windows, OS X, Windows Phone, Android, Apple iOS, Linux , as well as on the Wii, PlayStation 3, PlayStation 4, Xbox 360, Xbox One and MotionParallax3D displays (virtual hologram devices), for example, Nettlebox. It is possible to create applications for launching in browsers by implementing WebGL technology. Previously, there was experimental support for the implementation of projects within the Adobe Flash Player module, but later the Unity development team took a complex decision to abandon it.
Applications created with Unity support DirectX and OpenGL. Actively the engine is used by both large developers (Blizzard, EA, QuartSoft, Ubisoft) and Indie-game developers (for example, remake of Moral Utopia (Pathologic), Kerbal Space Program, Slender: The Eight Pages, Slender: The Arrival, Surgeon Simulator 2013, Baeklyse Apps: Guess the actor, etc.) due to the free version, user-friendly interface and ease of operation with the engine.
