Another ad directed by the great Rupert Sanders, this really amounts to more of a short film set in the Halo universe. It's that good. It follows a young future soldier through his induction into the Orbital Drop Shock Troopers of the game's title (ODST) and his first battle to a grizzled veteran honoring his fallen brothers. It's emotionally charged, incredibly relevant and visually stunning. If only the game had been this good.
