There are no cheats for Halo 2, or for any halo so far.
The only things that would be counted as cheats in Halo 2 are the effects from the skulls when activated. More information on the Halo 2 Skulls is provided in the link below.
there are no cheats for halo,2,and 3, just glitches and tricks,and you can look up alot of them on youtube
Well... yes. I would think so. I think the the way you would like to say that is "Do you know where I can find Halo 2 cheats?".
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. :)
