Want I really want out of Halo 4 is to be blown away by the Spartan control plot. I've always wanted to see controlling your spartan as a chance to do something creative with your approach on how you tackle a battle scene. Being able to jet pack out of a grenade or rocket scenario was very cool for Halo: Reach so I really wonder what the next great power for Halo 4 will be. I want it to be me in that suit, doing those actions. Just in your face, heart pounding, only one more kill moments. Really making it feel like reality. Just like reading a good Halo book, my favorite Halo: The Cole Protocol.
