There are no glitches, cheats or workarounds to earn all the achievements in Halo 3 illegitimately.
No, there is not.
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.
say youe gay x3 then erase you files and u will have all of the achievments
There is no glitch.
I do want to get all the achievements but i have xboxlive but can you tell me how to get all achievements in halo 3 in xboxlive.

no no NO!!! earn them yourself, lazy
Your work for them.
you need to achieve all the achievements. you need to achieve all the achievements.
To get security armor in Halo 3... all you have to do is get all of the original 49 achievements (you don't need the new mythic or legendary achievements).
Here is a complete list of all Halo 3: ODST achievements: http://www.xbox360achievements.org/game/halo-3-odst/achievements/For tutorials/guides on how to do them, simply put the names (i.e. "All Ears," "I Like Fire.) into YouTube along with the keywords "Halo," "ODST" and "guide", and you should be good.
Yes. Yes you do but the vidmaster achievements i Halo 3 arent the only ones you need to get Halo 3 ODst and there are more you need to do
