RBSE Hardcore Edition

Rah's Bionics and Surgery Expansion - Hardcore Edition

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 !

- 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. (Normal version below.)

-- 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 140 plasteel and 6 components.)
- Most simple prosthetic parts cost steel and components. (ex: 1 simple prosthetic arm costs 140 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 Normal Version: 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 parts spreadsheet:[docs.google.com] All RBSE part values. (Google doc links blocked on steam. link is 100% safe)
- More Vanilla Turrets - Rebalanced: New rebalanced turret mod for Rimworld 1.3 with 13 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 !

Research requirements for surgeries?
Rah  [author] Apr 11 @ 11:45am 
updated to 1.5. if you encounter bugs, please report.
Eddy63 Mar 3 @ 12:47pm 
Alright thanks for clarification
Rah  [author] Mar 3 @ 12:26pm 
That's part of the vanilla game. You can't harvest natural eyes.
Eddy63 Mar 3 @ 3:41am 
To add to my question ... does this mod remove natural / organic eyes? There is no eye in storage options, nor in the dev spawn items command to be found. Were natural/organic eye items removed by this mod or by vanilla?
Eddy63 Mar 3 @ 3:15am 
I'm confused I just installed a bionice eye where an organic eye used to be. I was expecting to get the organic eye afterwards, but it didn't. Is this part of your mod or is this new vanilla behavior? How does one get organic eyes then? Only way to fix a body purist.

@Rah Thank you for answer!
Rah  [author] Feb 23 @ 6:10pm 
yes, you can play with either version.
Eddy63 Feb 19 @ 1:47am 
Im only running the hardcore version and it works, so im pretty sure its standalone
Slikkelas Feb 19 @ 1:19am 
Im using RimPy and have a hard time figuring out if the hardcore version is standalone, or should be loaded after the normal version?

Deep inside i know this is a standalone version, but nice to be sure. I could test it, but it is a long loading time and hard when you don't have the research yet.

okay fair enough
