If you're looking to expand the list of armor in the game, the CROSS Cybernetics mod is one to take a look at.
This mod delivers a light version of the game's Power Armor that you construct at a special Cyber Crafting Bench.
There are several different pieces of armor and each of them comes with a significant amount of customization, far more than you get with vanilla armor. There are firmware upgrades, implants, paints, patterns, and more.
The armor also looks fantastic, like it belongs in the game, an added perk for one of the best Fallout 4 armor mods out there right now.
If you've exhausted all of the armor in the game and you want something new, consider CROSS Cybernetics. We love it.
