Craft prostheses! There is a wide array of them, from hook hands to advanced bionic parts. If your colonists tend to lose their organs very often, this mod is for you! Starting with basic prostheses like a peg leg or a hook hand, you can research everything you can think about: simple prostheses like the vanilla ones and some new ones, bionic body parts and even advanced bionics made out of a new, valuable material: Vancidium.
