So, last week, I passed the 750 gamerscore mark in Halo 3, now I have somewhere around 850 in Halo, but the game will not give me the security shoulders. I have gotten them via glitch before. I was wondering if anybody could help.
They say that they unlock permenantly at 1000, for the guaranteed gain. But the Security shoulders are, and have, always been buggy. There's nothing new there.
Get the original 49 achievements (likely that you have them already) I unlocked them at 750, but they unlocked themselves soon after, then stayed unlocked at 900.
