None of the Halo's have any 'real' cheats, the only one is the lower your weapon one, which is just like Halo 3's.

Halo 3 has only come out for the XBox 360 so far, and there are no cheats, only Easter eggs and glitches.
There are no cheat codes for Halo, only mods.

There really isn't Halo 3 cheats except for manually done cheats from the controller itself. This cheat is a way of holding down your gun like master chief in one of the Halo 3 posters. If talking about like " type in this cheat and you unlock all the maps cheat" well no. There are no cheats like that for Halo 3. :)
