From Halopedia, the Halo wiki
There are a four difficulty ratings in Halo games Easy, Normal, Heroic, and Legendary (do not get Heroic and Legendary mixed up with the Heroic Map Pack and Legendary Map Pack). Each difficulty has a different symbol. In Halo 3 you cannot get any achievements from the easy difficulty. You get 125 gamerpoints for completing the campaign on Normal, 125 gamerpoints for completing the campaign on Heroic, and 125 gamerpoints for completing the campaign on Legendary (these points can only be achieved once). But if you complete all campaign missions from mission start on Heroic, it unlocks achievement for Normal, if not yet earned, and if you complete all campaign missions from mission start on Legendary it unlocks achievements for Normal and Heroic, if not yet earned. Two unoffical difficulties can be played, Mythic- Legendary with the Mythic skull activated and Ultra- Legendary with ALL skulls activated.
