I am also in need of some help getting 4 of the achievements. I have all of the achievements for the other Halo games(excluding Wars) so I’m not a Noob. I just have no one who wants to play or help. I need the 2 on Two Betrayals, and the 2 on Library. I still need the one on The Maw, and the one on Keyes, but I can get those if I try harder. My Gamertag is K405NK0NFU510N. The O’s are Zeros. Anyone who wants to help I would be grateful,but please, No Kids who just wanna screw around, Serious people a must. Thank you.
