Hi, this is a mod I made, it took about 3 weeks. It uses a few features you have seen before, but this one brings a lot more to the playing field. 6 customs classes that you set your self, for both primary and secondary weapons, 9 modes, and the ring of lights tells you whats going on.
If you check it out on my blog it gives you schematics, and code. It's pretty easy to fallow its just really hard to build it small enough to fit inside the controller.
