Advanced Level Specialisation

I found this video clip, which I think is at an advanced skill level to do. I personally do not know how to create this, which is a rocket launcher with its own HUD and even a missile tracking system. Seems like you may have to alter the game more, and most likely edit some C++, create your own images and text, and most definately scripting for the auto tracking of the missle. This link may if updated show a tutorial on how they did this, it is obviously achievable.
