Halo 3: ODST Achievements

what are the achievements you have unlocked, and how?

All of them except Naughty Naughty and the Firefight point achievements, I have the ones for Alpha Site Interior and Lost Platoon, need the other ones though.
I just generally played through the game for story related achievements, went hunting with a friend for the Audiophile achievement, while ones like Saint I did a run through of campaign on my own to get.
The achievements in this were quite easy, only missing the ones I am because I haven't been to bothered to try getting them, although the vidmaster ones did annoy me a bit, Classic wasn't to bad, Deja Vu was mehish, Endure killed a part of my soul however.
Not because of the difficulty however, it was mainly because when I first attempted it I got to set 4 wave 1 round 1 when my live messed up major, got it with no interruptions afterwards though.

the achievments on this are really easy to get, but are one that you generally can't be bothered to get. i'm missing about 7 or 8 including legendary, most of the firefight ones and the audiofile one.

If anyone has achievement hints, please feel free to submit them:
