Tacolizard 7a64ded7a2 Adds cybernetic organs (#29276)
add: Added cybernetic organs to RnD, they can be used to replace organic organs. Remember to administer corazone during implantation though!
add: Added the upgraded cybernetic liver. It is exceptionally robust against toxins and alcohol poisoning.
