Unity

Unity: A multi-platform game development software that lets you create 2D and 3D games as well as smaller graphical projects

Unity is a feature-rich game development software solution that provides a modern environment where you can create 2D and 3D games which can be deployed on numerous platforms.

For any of the supported platforms Unity provides one-click deployment, but also a rich collection of optimization functions like asset bundling, occlusion, size stripping and culling.

The application comes with a flexible and versatile API that can be extended, and the deployment is designed so the games you create with Unity are optimized at runtime, have reduced bottlenecks and managing asset loading is improved.

You can quickly load assets into Unity via drag and drop, plus the app supports numerous audio, video, text and image file formats such as XML, PSD, TGA, BYTES, MOD and SM3, for example. Also, the application bundles native collaboration services which can be used by teams.
