go on YouTube and type in search halo3 skull and it will tell you where all the skulls are.
why?
Normal, heroic, or legendary.
Finish campaign and get all the skulls and do the score challenges and you should have close to 49
First there is one skull in when you have to shutdown the rings there is a building where u fly in the hornet in the inside of the building is a skull.
to get armor you must get achievement's and to get the haybusa armor you must go through the campain and get all the skulls from level 1 to the end of the game

find each skull on any level but halo and on any difficulty but easy. They are hidden in various places, some easy, some hard, some tricky, and some are out of the obvious.
you have to go to halo3 mods .com on google and click on halo3 how to mod
There are two ways you wont get the skull achievement even when you pick up the skull. Either you are playing the mission on easy or you started from a rally point. There are also skullls on maps, but you can only get to them in forge. And if you need help finding all of the skulls, you can just search "halo 3 skulls" on youtube and the top three or four are helpful. I hoped this helped you find other skulls.
Their isn't any cheats for Halo3
in my opinion halo 3odst
