The Cyclone Game Engine is a cross-platform 2D/3D game engine built upon MonoGame and the XNA Framework to help make it easier and save time creating games. The engine is still in its infancy stages of development. It is primarily built to serve the needs of Steel Cyclone Studios' game projects. More updates are coming so stay tuned!!!
As of 10/12/2012 Jordon McClain aka: Jdawgg recently got the skybox functioning inside the Cyclone Engine. Stay tuned for more updates! :-D
