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.
- More subtle graphics for Bionic and Archotech eye.
- 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. Don't need a patch.
- 1.3 Hardcore Armors Advanced power armor mod. Vanilla friendly !

I figured ofcourse after dumb as i am. Just thought i wanted to let you know, considering the other guy likely has made the same mistake.

they are not compatible. scroll up and you'll see: "RBSE is a standalone bionics and surgery mod. Do not install RBSE with EPOE."

Rah i have the same errors.
They come from running your mod and Expanded Prosthetics and Organ Engineering.

Run seperatly i get no errors. Running them together in any order gives the Joywire and Painstopper errors.
Rah  [author] Jun 11 @ 12:11pm 
what kind of errors? do you have other bionic mods installed?
nobita Jun 11 @ 6:50am 
I'm getting errors with joywire & painstopper

You can use dev tools ingame and remove hediffs manually. Just enable them in the options. I'm not sure which mods you are using, but I don't recommend mixing other bionics and surgery mods.

can you add in a toggleable feature to force allow people to be able to amputate anything with a hediff on it? It seems like one of my mods is conflicting and not allowing me to amputate things I should be able to amputate, this feature I'm asking for is a "use at your own risk, may break game" kind of last resort feature to save colonists that broken mods normally wouldn't allow to be saved

Hi, I'll see what I can do if I get some time.

Hello Rah, can you please Update the German translation?
Due to your latest updates, the translation is a bit out of date
