Help with the Halo 3:ODST Deja Vu achievement?

[Rob]

I need 3 people to help me get this achievement. I also don't have any of the firefight achievements either if some people wanna help with those too. Message me on XBOX LIVE.

I don't want anyone who will quit. i want people who will stay until the achievement is done.
