Can anyone help me get cheats for Halo 3?

[random p]

i am having a little bet w/ my cousin that i can kill her 35 times in the game and get to use one cheat...but if you have more than one that will be great. I need unlimited ammo, or life, or a really good weapon. And some tips would be nice. And ladies, yes, I'm single, but I'm not a nerd and I'm available

Umm, I think this is probably the worst place you can look for chicks in, but still, there are no cheats in Halo 3 unless you wish to spend $1000+ dollars for a DevKit to mod any game on your Xbox, but you still may get banned from Halo 3, just use skill to win, do you really need cheats to win? Good luck then. hope I helped.
