Why Atomic?

The Atomic Game Engine is powerful 2D/3D technology developed by industry veterans. It is available under the MIT license as an alternative to proprietary binaries, excessive fees, and royalties.

Atomic is available to professionals and is being used in production environments. It is also a great resource for learning JavaScript, TypeScript, C#, and the art of native C++ engine design.
