Hello, it has come to my attention that the security chest from halo 3 is no longer featured in the game. Im sure this is a bug or mistake by 343i and would love to see this issue resolved so I can have my favourite chest back. I have confirmed with my friends aswell, nobody can see it anymore on the equip chest menu of halo 3
The chest now comes with the security helmet. When you select the helmet the little radio thing on your back should appear
