You have to get 49 achievements first and they have to add up to 1000 or more gamerscore.
LAG
The Security Head and only be unlocked by getting a gamerscore of at least 1000 in Halo 3 with at least 49 achievements from Halo 3 unlocked. Before Title Update 2 this meant you had to unlock all the achievements to unlock the Security Head. Since the new achievements from Title Update 2, the head may be unlocked from any 49 non-vidmaster achievements.
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!
