DISCLAIMER:
This mod was created by EvaineQ. I claim no ownership over this and if the author asks me to take it down I will. The mod was taken down from the workshop recently without reason, so I re-uploaded it.
For future updates past 1.2, use Zaljerem's version.
This mod adds 13 new body parts/organs to the game, 4 new researches, and 1 new production table. It is a relatively lightweight mod but it adds interesting items. In particular, it adds 4 new "bionic" parts, 5 new "advanced bionic" parts, and 4 new "Cosmos-Tech" parts.
Below is the in-game description of the mod, I lost the original description of it so I wrote my own above.
<b>First release of Advanced Prosthetics</b>
<b>PROSTHETICS</b>
Prosthetics Rework: now they work in Stages which tries to Simulate the real-world system.
[Version 1.1]
Also, I don't develop mods (yet) and this is just a reupload, so I probably won't be able to tell you what this is or isn't compatible with, and I wont be able to help you troubleshoot.
