This engine is open source and free for you to do with as you want, just please credit us when you use it, that’s all we ask of you.
The engine has been written using XNA 4.0, so you will need to install that as well as DirectX 9c. It’s all in C# and we have used VS2010, and you should also be able to use VS Express.
At the time of writing, we are using Google code to host the code base, you can find that here, and so far we have a few samples to show how to use some of the elements of the engine, each sample will have a blog post here dedicated to it.
