If you are viewing this thread I am assuming you need at least one miscellaneous Halo 3: ODST achievement, these include:
- Audio Log Achievements (Audiophile)
- Naughty Naughty
- Both Tubes
- Wraith Killer
- Laser Blaster
- I Like Fire
- Be Like Marty
- Pink and Deadly
- My Clothes!
And any other achievements you need including the Firefight 200,000 points achievements.
I can help you get these achievements fast and easy, I am experienced at Halo 3:ODST and have got these achievements on at least 3 different accounts so I know my stuff. So if you want any of these achievements just reply to this post or send me a message and I'll try to arrange a suitable time.
