Thanks for your comments and views, the youtube video i posted a few months ago has reached over the 10k mark and is still proving a good way to boost the fire controller achievement.
Over 50% of the people who have used my method have got the achievement first time, the rest have had trouble finding the correct map or someone to boost with ...
If you've not watched the video and you want that horrible achievement then watch the video.
Please note: I dont own the game anymore so please dont send me friends invites to boost on xbox live.
i'm open to questions if any.
