I unlocked the skull helmet in the second page of season 8 and when I go to equip it on the halo 3 armor select it still shows that its locked. Any ideas would be appreciated.
I don’t have the unlock screens memorized, but is it possible you unlocked the helmet for Reach instead of H3? I believe most (if not all) armor pieces in Season 8 need to be unlocked twice - once for Reach and once for H3.
