I've noticed that atleast three achievements for CoD take quite a bit of time and I don't even have the easy ones. Stand-In (Esemble Cast), Quiet on the Set and Time Travel Will Tell.
I know about how to do them but I can't ever get a team of mature players to help me. Youtube showed me how to do them but it would help if I had somebody that already has the achievement so I know what not to do wrong.
Please message me back via Xbox Live mssging.
