After finding all nine Golden Skulls in Halo 3, you are awarded a unique armor permutation: the Hayabusa Helmet. The next step is to get 1000 gamer points from Halo and then you also get a Samurai sword to go with your fancy new helmet, like this guy.
So if you want a fancy new helmet, let me know and I can walk you through getting all the skulls. Remember you must have all the skulls to get the armor. They're also a good way to boost your gamerscore...
Next, I had a little fun with the Halo physics engine. All it took was a little Forge work, with 20 or so Fusion Coils and a Mongoose and sky high I went, right into a beam.
Little did I know that in slow-mo the Master Chief becomes Stretch Arm Strong.
