I’m currently in the process of making a comprehensive list of all armor customization items in Halo Infinite in order to make it possible to count the total number of customization combinations (Armor Emblems excluded). Due to this, I would be happy to know which armor customization items has been available in the store and this includes all items in the classes Armor Coatings, Helmets, Helmet Attachments, Visor Colors, Chests, Left/Right Shoulder Pads, Wrists, Utility, Gloves and Knee Pads for any of the 3 Armor Cores.
Can this game be Data mined at all to see this?
