Since no one placed a solution for this bad boy, I guess I will. This guide in the link below works really well, but unfortunately I don't have the time and patients at the moment to fully 'challenge' myself... also my Xbox keeps freezing on me when I make progress.
ALL CREDIT goes to Dracophile, for the link.http://www.xbox360achievements.org/forum/showthread.php?t=33...
I'm also including the challenges in video by Moonknight360 for the first 6 challenges and the last one (the 6th video) is the 'Groupium' challenge 10 from shrouwehkuggah7777
This solution is just all of the available resources put in one place. If you have any helpful tips, please comment and I'll add them. Sorry that challenges 7-9 are not listed in the videos, but the guide above is just as good. I hope this helps, enjoy! :]
