I got itn yesterday and heres how.
I had got a lot of the online 6 player acheevs out the way but was also doig the story mode as well.
I didnt do any of the co-op missions left them to after i had fully completed the game, popped with no problems
Then i done the 5 and 10 scene ones and they seemed to pop up earlier than expected.
Actually completed 96 retail games, Fifa 10, Fifa Street, Madden 10, Quantum of Solace, Dante's Inferno & Brothers in Arms : HH all missing.
