No. Bungie's gives you the armor as an award. You can't cheat the armor, unless you can cheat them.

No.
All the armor are the same it's just the way how you want to look WRONG! the best armor in halo 3 is the recon armor and you have to be a member of bungie OR get all 7 vidmasters in halo 3 ODST
Actually, that doesn't work. To get all the achievements in Halo 3, you just have to work for them. I got 1575g just by working for them...there is, however, a way to get all 1750g in Halo 3 by manipulating your gamerscore, but that's a bit more complicated.
you get all the vidmaster achievements on halo 3 and halo 3 odst
There are no glitches, cheats or workarounds to earn all the achievements in Halo 3 illegitimately.
