No.
There isn't a known cheat code for this on Halo 3.
No. Bungie's gives you the armor as an award. You can't cheat the armor, unless you can cheat them.
there is no permanent cheats in halo 3. you need to unlock them by achievments. and, you can not get the flaming armor effect, it is only for bungie employees. in halo reach, buy the legendary package to get that armor effect.
You have to download a mod, there is no halo armor in the game itself.
no just work for the armor

No, there is no armor in Halo 3 that has a knife in the shoulder.
There is no Brute armor in Halo 3, only Elite and Spartan models.
I'm sorry bud but there isn't a cheat code to unlock all the armour in Halo. PERIOD.
