Steel Cyclone Studios is currently working very hard on the Cyclone Game Engine. The Cyclone Game Engine is a 2D/3D game engine built upon the XNA Framework to help make it easier and save time creating and developing games. The studio is integrating MonoGame to help port its games to the iOS, Android, Mac OS X, Linux and Windows 8 Metro. More updates will be coming soon, 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
