I have some idea
- *Spoiler alert*
Why not add robots: they could start inventing them engineer Socket, and their number could be increased by her, although they had a built-in AI, because of which they could do anything and you could do anything with them, if desired, they could even be turned off or break it in a fight and later dispose of it, or have it repaired by a naked engineer
What could be done with them: give them any clothes and weapons, use them as sex slaves or sex dolls, they were reliable unless of course their settings and preferences were changed later, and also program them with the help of chips that can also be bought from an engineer, these chips set up the character and behavior of the robot and they could be turned on in the inventory (or through another setting), but they require fine-tuning during creation and are produced in a factory in the mine:They could, if they wanted, enlarge their breasts, choose their appearance, hair (wig), etc.like when creating a character...or maybe add a new type right away?...and yes, these robots could be hybrids or full-fledged furries only without fur but having silicone skin, or like protogen
