The short answer
Cyberpsychosis is a serious rules-and-tone topic, not a shortcut to make an augmented character into a monster. The Core Rulebook connects it to Humanity, Empathy, dissociation, voluntary augmentation beyond the human baseline, and trauma. It also states plainly that cyberpsychosis is not necessarily violent. Use its mechanical thresholds accurately, but agree on the table's boundaries before the fiction gets personal.
For a player character, distinguish roleplaying guidance from loss of control. At lower Empathy thresholds, the book asks the player to portray escalating dissociative pressure. The character is handed to the GM only at zero Empathy with negative Humanity, and returns to the player when Humanity is positive again. Make that possibility explicit before it can surprise anyone.
Hot take
Do not wait until somebody reaches a threshold to decide what cyberpsychosis means at your table. The best time to establish lines, veils, player agency, and what recovery looks like is before the first elective installation or traumatic job.
The caveat is that the rule can still matter. Removing every consequence makes Humanity feel cosmetic. The better approach is to make the consequence legible and consented to: strained connection, needed downtime, a clinic relationship, a crew check-in, or a hard choice about the next job - never a surprise excuse to make someone violent.
Read the Core Rulebook in two layers
The Core Rulebook contains both fictional framing and a usable mechanical procedure. Keep them separate so neither is flattened into a stereotype.
| Layer | What the table should take from it | What not to do |
|---|---|---|
| Humanity and Empathy | Humanity Loss can lower effective EMP and create roleplaying pressure. | Treat a number as a real-world diagnosis or moral score. |
| Augmentation and trauma | Elective enhancement and traumatic events can matter; therapeutic replacement is handled differently. | Say that every augmented or disabled person is on the same path. |
| Cyberpsychosis | The game presents dissociation and escalating behavioral guidance. | Assume violence is automatic or inevitable. |
| GM control | The book has one defined extreme condition for handing a character to the GM. | Take control earlier because a scene feels dramatic. |
| Therapy | Treatment and recovery are part of the game world. | Use care as a punishment, reset button, or required on-screen trauma scene. |
The Humanity Loss Guide covers the broader cyberware, trauma, and therapy decision. This guide focuses on how to run the cyberpsychosis material with accuracy and care once it approaches play.
The thresholds need a clear agreement
Cyberpsychosis runs on Empathy, and Empathy runs on Humanity. A character has 10 Humanity per point of EMP, and each drop in the tens digit of Humanity lowers effective EMP by 1. The Core Rulebook then sets five steps:
| Current state | What the Core Rulebook says |
|---|---|
| EMP 3 or higher | No cyberpsychosis or dissociative disorder. |
| EMP 2 | Borderline dissociative disorder; the player roleplays it. |
| EMP 1 | Dissociative disorder and borderline cyberpsychosis, with at least 3 strong traits from the Hare Psychopathy checklist. |
| EMP 0 | Cyberpsychosis, with at least 5 strong traits; the player still roleplays it. |
| EMP 0 and negative Humanity | Extreme cyberpsychosis; the GM plays the character until Humanity is positive again. |
Don't let the table discover those steps during a crisis. Open the book together and agree on the procedure before the campaign reaches it.
The practical distinction is straightforward:
| Situation | Player agency | Good table practice |
|---|---|---|
| EMP is under pressure but not zero | The player remains in charge of their character. | Ask how much of the book's roleplaying guidance the player wants visible. |
| EMP reaches zero | The player still roleplays the character under the Core Rulebook's guidance. | Pause briefly, restate boundaries, and avoid equating the condition with violence. |
| EMP is zero and Humanity is negative | The Core Rulebook hands the character to the GM until Humanity is positive again. | Confirm the consequence, establish a humane off-ramp, and do not use control as punishment or spectacle. |
| Recovery becomes possible | The player can regain agency when the book's condition is met. | Make care, support, downtime, or removal choices available in the fiction. |
The values and full behavioral guidance belong in the Core Rulebook. What belongs in the session conversation is how those rules will feel at this particular table.
Cyberpsychosis is not a violence rule
The Core Rulebook explicitly says cyberpsychosis is "not necessarily always violent." It says the dangerous cases are people who had already shown psychopathic or sociopathic tendencies, whose tendencies get magnified. Preserve that distinction. In the setting, violent cyberpsychos who threaten public safety are hunted by the Psycho Squad (C-Swat), which shows how the world treats the extreme end, not how every case plays out.
For GM practice, this means avoiding three common mistakes:
- Do not introduce a character with cyberpsychosis only as a combat encounter.
- Do not use real diagnostic labels as casual villain shorthand.
- Do not decide a player character's actions because their Humanity is low unless the book's defined GM-control condition applies.
Instead, show stakes through a player-approved signal: withdrawal from a trusted contact, a moment of disconnection, an impulsive but nonviolent decision, a clinic warning, a missed routine, or the crew noticing that their friend needs support. These create meaningful pressure without claiming that mental illness means danger.

Set boundaries before the job needs them
The Core Rulebook itself recommends working out boundaries around difficult material. Cyberpunk RED can include body horror, surgery, trauma, addiction, coercion, violence, and mental-health themes. A simple pre-agreement makes the rules safer and easier to use.
Before play, answer these questions:
- Are surgery and body modification on screen, veiled, or absent from description?
- Are trauma-induced Humanity consequences part of this campaign, and who can call for a pause?
- What language should the table avoid when discussing cyberpsychosis?
- If GM control becomes possible, does the player prefer an off-screen transition, a jointly framed scene, or another agreed method?
- What recovery resources exist in the campaign: a Medtech, a clinic, a trusted NPC, downtime, or a crew safety plan?
Revisit the answers when the campaign changes tone. Consent is not a one-time character-creation checkbox.
Make recovery a real route
The Core Rulebook includes therapy that can restore Humanity. A Medtech spends a full week with the patient and then makes a Medical Tech Check: standard therapy (500eb) restores 2d6 Humanity, and extreme therapy (1,000eb) restores 4d6. A failed Check wastes the week. Cyberware installed with Humanity Loss lowers the maximum Humanity by 2 per piece (4 for borgware); cyberware installed with 0 Humanity Loss does not lower that maximum. Removing chrome can therefore be part of recovery. Those limits already make recovery costly; the table does not need to add humiliation, forced violence, or hopelessness.
Use one of these approaches according to the group's preference:
| Table preference | Recovery framing |
|---|---|
| Character-focused | A trusted teammate, Medtech, or clinic relationship becomes a quiet roleplaying scene. |
| Job-focused | The crew needs money, time, or a contact to make treatment possible before another contract. |
| Low-detail | Treatment and check-ins happen off screen, with only the mechanical outcome and changed schedule recorded. |
The Cyberpunk RED GM Guide is the companion for turning that pressure into choices rather than a predetermined crisis. Put real options on the table, telegraph their consequences, and let the crew decide how it supports one of its own.
A five-minute gm check
Before using cyberpsychosis material in a session, verify the following:
- The exact Empathy and Humanity state from the character sheet and Core Rulebook.
- Whether the book calls for player roleplaying guidance or GM control.
- The player's stated boundaries and preferred scene detail.
- At least two non-punitive choices for support, safety, or recovery.
- The difference between a difficult character moment and an excuse for an unwanted violent encounter.
Then state the stakes plainly. A table can handle strong material when it has informed choices, shared expectations, and a way back to player agency.
Where to go next
- Return to the Cyberware Guide for the live hub on Humanity, prerequisites, capacity, care, and chrome decisions.
- Read the Humanity Loss Guide before treating EMP, therapy, trauma, or cyberware as a simple equipment tax.
- Use the Cyberpunk RED GM Guide to frame consequences as fair job pressure and player-facing choices.
- Read the Cyberpunk RED Medtech guide for Medicine, therapy context, and care around cyberware procedures.
- Return to the Cyberpunk RED Guide Hub or browse the guide directory for the complete live library.
