Defense Commander

icon Defense Commander was an early demo/mini-game by Titanium Studios, it was created for Microsoft to demonstrate simultaneous cross platform development and networking between the Dreamcast and the PC.

The project was developed from scratch, it has plenty of cool features such as detailed fractal terrain, spherically mapped multipass sky, trick tracer fire rendering code and cool particle effects. It also features a C++ AI system and multithreaded client side predicted networking.
