Ive found this halo 4 editor Ive tested the unlock all feature and have not been banned the owner states that everything in the editor works but be careful heres the link and like i said Ive test the armor unlocking feature and it does work without any problems and Im playing online [ Register or Signin to view external links. ]

Works on win 7,8,xp,have not tried vista but i don't see why it wouldn't ,i was told by the owner it doesn't work with mac

STEP ONE- OPEN modio grab your profile and extract to desktop

STEP TWO- open ellipse then open halo 4 editor

Step THREE- open profile in halo 4 editor..edit..save..done

STEP FOUR- put modded profile back on usb and play halo 4 with all your armor

STEP FIVE- post legit if you do it

this isnt the best tut but for experienced usb modders its very easy and simple
