does anyone know any halo 3 cheats??

[j_reznack]

anything like unlimited health or ammo. im on the level CORTANA and i cant beat it, its the only one thats given me trouble. i already have the skulls. i have 12/13 and i need to beat this level to finish the game and get the last skull. PLEASE DO NOT POST ANYTHING ABOUT THE ARMOR
