well I got my security shoulders when I reached the gamescore of 850. That sucks I know but I got Katana and security helmet at the same time at the gamescore of 980...pretty glitchy eh? My friend got them when he reached 450. Security shoulders are known to be really glitchy :D
Yes, there is a Security armor in Halo 3, Only the head and shoulders are unlockable.To get the head, you need the gamerscore in Halo 3 to be 1000g/1000g. And for the shoulders, the gamerscore is variable from 700-800 for some reason. (Note: If you get the shoulders, there is a glitch that makes you lose them when you earn them, but don't worry, they return back.)I hope this is useful!
