GiTS Cyberbrains

This mod adds 23 cyberbrains from the world of Ghost in the Shell! These are advanced brain cybernetics where micromachines graft microcircuitry to organic tissue, creating a hybrid of the original brain tissue with cybernetic components known as a cyberbrain. Cyberbrains have increased mental capabilities and many offer a variety of abilities from controlling the user's pain sensitivity to connecting to Net databases to temporarily boost skills when needed most.

Cyberization of the brain offers increased rewards and drawbacks depending on how much matter is cyberized. A colonist with minimal cyberization will see some benefits, but nothing near someone with extreme cyberization. At the same time, the colonist with minimal cyberization is the least likely to suffer from changes to their mental state as well as risks of cyberbrain diseases.

As this mod mainly adds brain cyberware, I have made sure to add support and encourage the usage of another bionics mod with this one with a multitude of mod integration patches included inside.

This mod adds 23 cyberbrains with a dedicated research tree as well as abilities, micromachines with multiple medical applications, cyberbrain diseases, and more!

Cyberbrains primarily provide bonuses to consciousness, manipulation, research speed, and learning speed to varying degrees depending on the level of cyberization. More advanced specialized cyberbrains will also offer bonuses tailored to various niches; work cyberbrains may grant bonuses to reduce chances of food poisoning if designed for cooking, while a combat cyberbrain may be specialized towards melee cooldown time or move speed.

Fabricating a cyberbrain requires micromachines and is quite an expensive up-front cost in research and resources. Such advanced neurotechnology requires researching brain cyberization and skilled technicians, so make sure your colonists have passable medicine and crafting! Once installed, the user will also take some time to adapt to their newly cyberized brain depending on how much matter was cyberized. Make sure to watch your colonists during this stage, as they will have reduced abilities and are prone to cyberbrain diseases during this stage.

• Basic Cyberbrain:
  
  • This is the most basic cyberization process which leaves around 90% of the brain intact and has essentially no drawbacks. Once complete, the user will see minor bonuses to consciousness, manipulation, and learning speed. They will also be able to access the net, allowing the user to receive work speed bonuses for some time. After installation, users will only take about a day to adapt to the cyberbrain.

• Enhanced Cyberbrain:
  
  • This is a general upgrade over a basic cyberbrain with 80% of brain matter impacted and sees exponentially higher bonuses. However, drawbacks also begin to appear. Users will take around two days to adapt and start to suffer heightened emotions, leading to mental state drawbacks.

• Specialized Cyberbrains (8 combat bonused, 11 work bonused):
  
  • Similar to enhanced cyberbrains, specialized cyberbrains integrate additional systems to tailor unique bonuses for various niches in both work and combat. There is also an advanced specialized cyberbrain subcategory combining the bonuses of similar roles into one. This tier mirrors enhanced cyberbrains in adaption time and drawbacks and offers the best balance of overall bonuses to drawbacks.

• Extreme Cyberbrains (1 combat bonused, 1 work bonused):
  
  • Pushing cyberization to its absolute limits, extreme cyberbrains replace up to 97.5% of brain matter and offer unmatched capabilities. Drawbacks are quite severe with greatly heightened emotions leading to a fragile mental state as well as increased social fight chance and increasing the adaption phase to three days for the user.

As mentioned above, during the adaptation phase of cyberization a colonist may contract a cyberbrain disease. The more brain matter cyberized, the greater the risk of contracting one.

• Cyberbrain Sclerosis:
  
  • Cyberbrain sclerosis is an extremely rare cyberbrain disease where the afflicted's brain tissue begins to harden. This will result in memory loss over time, talking inhibition, and eventually after 30 days; complete brain death. There is no practical cure for this disease, be careful!

• Closed Shell Syndrome:
  
  • Closed Shell Syndrome is a rare cyberbrain disease where a user will shut themselves off from others. This can be compared to trauma savants in Rimworld, with those afflicted becoming savants in computing and other niches that may prove useful. It is not fatal.

Micromachines not only provide the basis for producing cyberbrains and CCSM lethal injectors but can also be programmed for a variety of medical purposes! Nanites can be administered to colonists to boost their immunity or combat ailments from food poisoning to organ decay.


This mod is fully compatible when loaded after Combat Extended and will take advantage of new stats added by it, as well as providing additional CE-specific micromachine surgeries. Feedback on balancing is always accepted and appreciated.

• Safe to add to save games. It's never safe to remove a mod from a save, but removing this mod should not cause significant issues.
  
• Should be compatible with essentially all bionics mods out there with no currently known incompatibilities.
  
• All cyberbrains will take advantage of Elite Bionics Framework if it is loaded, and have three levels of durability based on the cyberbrain type: thin metal shell, metal shell, and advanced metal shell.
  
• Includes 19 new cyberbrain-related achievements for Vanilla Achievements Expanded.
  
• Mod integration patches support EPOE-Forked, FSF Advanced Bionics, RBSE and RBSE Hardcore, Greyscythe Bionics Catalogue, Dubs Rimatomics, Eccentric Tech, Bionic Icons, Alternate Research Projects, and more!
