So I put the codes in for the Raider Helmet, Torso, and Shoulders and it says they have been unlocked. Are there any other steps I need to take before I can use them in game? Do I need to find all the terminals in H4? I have beaten every Spartan Ops missions in Normal. Any help would be great, Thanks
You should be able to use them. No other steps.
If it says that they have been unlocked, then they have been unlocked. 
Cool, thanks. Can you not thank people in the forums anymore? I can’ find it
