Thanks for the guide. I'm not fond of this game but I will eventually get back to it just for the points.
Started Using x360a.org - June 2008 - 3K Gamerscore
Hit 100,000 GS on 12/22/2011 with Mile High Club - thanks to all the boosters and this great site.
Looking to Boost: Halo ODST - Endure Only, Ghostbusters, Quantum of Solace, GTA IV Multiplayer, Halo Reach DLC
Message me on XBox Live if you need an extra player for any of those.
