I have a question, u seem to kno a crapload of a lot about halo 3, so i was wondering. I got security and katana and stuff like that and i was really excited about it, but then i turned off my xbox and it was just randomly gone. i tried resetting my xbox several times, and restarting it, but nothing worked. It took away my security AND my katana, can ya help me out? and btw some other of my friends got the 1000 g in halo and had lietenant, and had all the skulls, but didnt get it like i did b4 using it. y is this?
