I think you should be able to play as Thel' Vadaam from before he became the Arbiter for the covenant and Master chief for UNSC. At the beginning of the game, you should be able to choose Covenant or UNSC before the difficulty selection, and there would be an ability (exclusive to campaign only) that only one or the other could use like in Halo 2. For example, Thel' has cloaking while the chief has a flashlight, or Thel' can duel wield energy swords while chief can carry more ammo or somthing.
