Have you gotten all your Achievements Legit? (HALO 3)?

[A FIR3 IN5ID3]

I was wondering how many people have gotten Legit achievements?
I have, all my achievements so far

And which one was your hardest?
For me it was... Overkill
But it was funny when I got it
I was on Epitaph, with a shotgun, shields partially drained when I hid behind a shield door
Here they come, one backs into it, the other follows and two more come
Shoot, bash repeat
Overkill
And now I'm enjoying my Commando Helmet
