What this mods does to sum things up : It adds the Biosteel silk, a new crafting material to the game with its related furnitures (bench, loom, container). You will have to find in Kenshi's world where that damn silk is and i won't help you ! With that material in hand and with the proper research(s) you will be able to craft an interresting array of new armours. It will be rewarding, these armours are still using original game meshes but they come with brand new textures and also gain fairly better stats than their original versions while never being overpowered (because we love to keep the difficulty close in this game right ?).
