The Robot Game Kit is a complete mini game for XNA Game Studio. The project comes ready to compile and run, and it's easy to customize with a little bit of C# programming. You are also free to use the source code as the basis for your own XNA Game Studio game projects, and to share your work with others.
Robot Game is a three-dimensional robot combat game that demonstrates the following components:
- Advanced graphics using shaders and post-processing effects
- Advanced particle system
- Collision detection, 3D positional sound, input, and screens management
- Single-player mode and split-screen two-player versus mode
- Customizable game elements, such as robots, weapons, and items

The XNA 4.0 version of the starter kit was created by Bob Taco Industries. Check out their documentation for more information. I wish I had found this updated version sooner since I struggled to convert the Robot Game Animation Processor to XNA 4.0 as you can see in my blog post here.
