Rah's Bionics and Surgery Expansion

Rah's Bionics and Surgery Expansion

Main forum thread:

Hello fellow rimworlders ! This mod aims to enrich the bionics and surgery gameplay as much as possible, without being intrusive to the vanilla experience. While originally intended to be a streamlined and 'improved' version of Expanded Prosthetics and Organ Engineering, which it still is to some degree, it is now also a standalone and complete medical mod. This mod features all kinds of prostheses and bionic parts, bone repairs and scar healing surgeries, for your needs.

Your colonists will, however, struggle for a while if they lose limbs or become severely crippled in the early game, until you manage to craft the rare and expensive bionic parts. You can still make simple prostheses and repair shattered bones relatively fast after researching it, but the resource cost is quite high for most things. Peg legs, wooden feet and dentures are of course always available for free. ;-) Early colony life was never easy !

Rah's Bionics and Surgery Expansion: The normal version is a bit more 'fair', in terms of resource costs, compared to the Hardcore Edition. Great for medium difficulties, especially on Randy and Phoebe.

-- RBSE is a standalone bionics and surgery mod. Do not install RBSE with EPOE --

Main features:

- Bionic Workbench: craft an array of bionic prostheses. (simple parts available at a machining table)
- Advanced Medical Station: craft advanced bionic prostheses, synthetic organs and brain implants.
- Bone repairs for femurs, tibias etc. (spinal fusion included)
- Old scars and gunshot wounds can be cured with Glitterworld medicine after research. (brain scars must be cured in other ways)
- Cures for Frailty, Sleeping sickness, Muscle parasites, Mechanites, Gut worms and other infections. (Late game tech)
- All bionic parts cost quite a bit of resources, mainly in plasteel and components. (ex: 1 bionic arm costs 80 plasteel and 6 components.)
- Most simple prosthetic parts cost steel and components. (ex: 1 simple prosthetic arm costs 120 steel and 4 components.)
- Balanced bionic parts: Decked out bionic pawns are powerful, but not game breakingly overpowered.
- Organ rejection system for natural organ transplants. (vanilla friendly) (can be toggled on/off in mod settings)
- Organs need refrigeration to avoid rot and decay.
- 3 new chronic diseases: Chronic kidney disease, congenital heart defect, chronic stomach disorder.
- 3 new brain implants for the late game. Enhancing effects and brain disease / damage cures.
- Bionics and surgery research tree with its own research tab.
- 3 implant colors: Light blue for simple parts, blue for bionics and purple for advanced parts.
- Medicine and Glitterworld Medicine have original red colors from A16.
- White textures for Royalty parts to better fit the medical theme.
- Death Acidifiers can be removed after researching Advanced Bionics.
- Redundancy kept to a minimum.
- Bug fixes and balance work.


- RBSE Hardcore Edition: This version has higher resource costs, and is therefore best suited for players who are looking for a bigger challenge. Works great on the harder difficulties, especially with Cassandra.
- RBSE parts spreadsheet:[docs.google.com] All RBSE part values. (Google doc links blocked on steam. link is 100% safe)
- Rah's Vanilla Turrets Expansion: New rebalanced turret mod for Rimworld 1.3 with 9 strong turrets for the mid and late game !
- A Dog Said link. Still works for 1.5.
- 1.3 Hardcore Armors Advanced power armor mod. Vanilla friendly !

@Oiler1k, hi, if you have completed the research, you only need glitterworld meds available and a competent doctor. If they have a brain scar, you will need to solve it in a different way; neurostimulator, mech serum, luciferium etc.
@Marcus, it's not. the old A dog said version was updated a last time for 1.5, so it should still work.
Marcus Jul 20 @ 5:59pm 
Looking at the mod A Dog Said... which has been updated into A Dog Said... Animal Prosthetics 2. Since this is now the main version updated for 1.5, do you know if RBSE is compatible with this as well?

Could you tell me how to use " Old scars and gunshot wounds can be cured with Glitterworld medicine after research." I can't tend to my colonists for it and I cannot set a operation. Thanks for the awesome mod Rah!
Rah  [author] Jul 17 @ 2:32pm 
Do you have the proper research?
Pyrahead Jul 17 @ 11:23am 
It does not give me the option to install a bionic leg or eye under the operation screen. Any idea how to troubleshoot that?
Rah  [author] Jul 16 @ 3:28am 
Organ transplantation is kind of a big thing, so it makes sense not to have it as a basic tech imo.
Exosais Jul 13 @ 11:58am 
Great mod, but I wish there was a way to disable the organ transplantation node, especially when using the Research Tree mod, so that you can transplant lungs before machining & microelectronics.
Rah  [author] Jul 8 @ 6:11pm 
That's a vanilla mechanic. Whenever you install limbs on pawns, the game automatically removes hands/feet, so you won't be able to wear rings, gloves etc. You also can't install hands on top of arms. But a bionic arm does function like a normal arm and hand. I believe the mods Prosthetic No Missing Body Parts and Medical System Expansion 2 change that, so you can still wear those items.

@Rah sorry i want to say can you allow both bionic palms and bionic arms to be installed on the human body simultaneously?
Rah  [author] Jul 7 @ 4:01pm 
@Metal, could you specify what you mean?
@Sahilarious, that's most likely just bad luck. The new chronic diseases are set to the same as the other vanilla diseases, so there shouldn't be any difference.
@Bmb92, I recommend contacting the CE guys. They usually are pretty quick to make patches and fixes.
