I'm holding off my thoughts until the Beta, when we actually get to experience the game first hand and not just a segment of the first cinematic to a currently alien game whose direction we really don't have a clue of yet. All we know is that it is Reach, and I'm doubting they would just do a game of a book (check out their newest Writer position for what they're NOT looking for to clue you in). Tie ins yes, but just like ODST, I'm betting this is a view from another angle in the battle.

Hmmm...well now, doesn't that moutain look familiar...
