There are no codes but there are "handy glitches to be used by skillful players" see the "Halo Exploits" thread in here.
And you're wrong about no Bungie FPS having cheat codes... The Marathon series had them, and even had computer terminals you couldn't reach normally, and when you accessed them they told you to stop cheating ;-)
