But for a game as in depth and involving as Halo is, with everything perfectly balanced as you lead a "one-cyborg assault on the Covenant", the aforementioned unlockable playtype would be a considerably different game, with different focuses and quirks.
It'd take focus away from the original gameplay. If it's there, kudos, but I highly, highly doubt it.
