Augmentation in Cortex Prime

The following is a system for handling (para)human augmentation, primarily for cyberpunk and other sci-fi settings, but adaptable to steampunk, fantasy settings or any other setting aspect involving implantation and supplementation of natural body systems to achieve spectacular effects.

While the base Cortex Prime Abilities or Powers systems could be skinned to cover the same material, this system attempts to unify this mechanical aspect of Cortex Prime under its own subsystem to both accentuate this component of setting and to provide for a more narratively cogent method of addressing (para)human augmentation.

Using Talents for Augmentation

Rather than using a Trait Set, as the mod below does, to represent Augmentations, you could simply create a list of Talent SFX, with each Talent representing a particular system. This might be the preferred system where augmentations are present in the setting but not a central feature (for instance, Star Wars has cybernetics, but they are typically background dressing).

Grit and Power Levels

At the simplest, these systems can be made a Trait set available to all characters, with a set number of dice to assign between specific traits. This works especially well with cyberpunk settings that have no mystical or magical aspects to balance against.

The relative power of each augmentation system can be adjusted narratively. For instance, does a d8 in Strength systems mean that a character can punch through concrete? Throw a car? Or simply that the character has a level of strength on par with world-class body-builders? Does a character with Cognition d8 have intellectual skills on par with natural geniuses (perhaps a more complex designation than once thought given developing neuroscience) or superhuman skills of calculation and analysis? Of course, the step of the system’s die can be factored in as well—dice at steps d10 or lower may be within the realm of natural human ability, while dice at d12 represent augmentation beyond natural human potential.

These narrative factors can be combined with mechanical effects to further define the relative power of available augmentations. If you are using rules like a Limited Dice Pool, you could have an Augmentation die not apply toward the limit—this will accentuate that augmentation really does allow someone to achieve beyond normal standards. If you’re also using a track for Stress and/or Trauma, you could also allow a player to voluntarily take a point of Stress or Trauma to add a third die (perhaps specifically the Augmentation die) to the result rather than spending a Plot Point to do so. For a middle road, allow the expenditure of a Stress/Trauma “point” to have the Augmentation die not count toward the Dice Pool Limit. I’d map this as an SFX that automatically applies to each System, much like the “Use a d4” mechanic for Distinctions.

These options may work especially well in settings where human augmentation is an important aspect of genre—such as cyberpunk or certain science-fiction. As a more specific example, this might work especially well in a setting like Eclipse Phase, where characters can “resleeve” into different bodies and you want to accentuate the importance of body selection.

The System Itself

The system itself is relatively simple. Rather than seemingly infinitesimally granular selections of particular upgrades and augments, this mod looks at the sum total, classifying the Traits in the Augmentation category as “systems” that represent the overall effect of upgrades. The systems I would recommend using are: Athletics, Charisma, Cognition, Perception, Reflex, Resilience, Stealth.

Whether you use the categories I’ve designated or substitute your own, you should give a general description of the system that explains what sorts of capabilities a person with that System has as a guide to when the die from the System might apply (or when possession of the system grants narrative “permissions” that may not be reflected in mechanics but in the sorts of things the character can do.

Specialized systems providing more discrete and specialized functions can be mapped as SFX. You may consider giving characters a certain number of SFX for free at each dice step or provide that certain SFX are automatically gained at certain dice steps.

If you’re using other Traits that have SFX, or if you’re using Talents, you’ll want to carefully consider whether your choices will lead to “SFX bloat” that will complicate gameplay inordinately over the value they provide. Additionally, you’ll want to think about just how much you want to accentuate Augmentations versus other Trait sets.

If you choose not to use SFX, then you might provide short narrative descriptions of the kinds of capabilities a System has at each die step.

I’ve provided sample write-ups and SFX for my Systems below. Given the length of the article (and constraints on my time), I’ve only included a few sample SFX in each System. When I am able, I’ll supplement those SFX in a subsequent post.

Systems Descriptions

Athletics: Athletics Augs enhance the strength, flexibility and endurance of a character (but not their reaction times, which are enhanced by Reflex Systems). These are the most-commonly thought-of augs for the average person, because they are at once those most obvious in action and those with the most directly frightening consequences.

  • Oh Yeah!: Spend a PP to smash through a wall, even if made of brick or stone.
  • Optimized Cardiovascular System: Spend 1PP to step up or double any Endurance Augs when taking an action. If the action fails, shutdown Athletics Augs. Recover by activating an opportunity in a Bridge scene.
  • Hyper-oxygenated Blood: The die step of any Complication of Difficulty die accounting for fatigue from physical exertion must exceed the Perception Augs die or the character disregards it. For any such Complication that does apply to the character, step it down by one step.

Charisma: Charisma Augs enhance a person’s social capabilities through a number of means. This may include pheromones or other chemical signals, analytical systems providing feedback on observed body language, voice modification for a more mellifluous sound, etc.

  • Empathic Analysis: When including Charisma Augs in a social Reaction, double or step up Charisma Augs. Pay 1 PP to do both.
  • Mood Stabilizer: Spend 1PP to ignore penalties from social or mental Stress or Trauma, or Complications, for a Test.
  • Halo Effect: Spend 1 PP to step up or double Charisma Augs on a test to persuade others. If the action fails, shut down Charisma Augs and recover by activating an Opportunity in a Bridge scene.

Cognition: This System covers augmentations that enhance the computing or analytical power of the human brain. Subsystems tend to enhance object identification, pattern analysis, sensory interpretation, creativity and intellect: human methodologies for competing with the power of artificial intelligence (whether or not that means “sentient and conscious” artificial intelligence or the complicated computing algorithms already in use today).

  • Multitasking: Split Cognition Augs into two dice at one step down or into three dice at two steps down.
  • Flow State: Step up or double Cognition Augs for one action, then step back to two dice at one step down. Recover by activating an Opportunity during a Bridge scene.
  • Probability Analyzer: Spend 1 PP to add Cognition Augs (or step up by one if already in your pool) and reroll all dice on a Reaction.
  • Efficiency Optimizer: Use two or more Systems dice in a single dice pool, reduce each System die for one step for each Systems die added beyond the first.
  • Overclock: Step up or double Cognition Augs for a scene, or spend 1PP to do both. While active, take Mental stress equal to the step up the second-highest-rolling die.

Perception: This System represents augmentations that heighten or expand the sensory perceptions of the individual—the ability to see in other parts of the light spectrum, to filter certain sounds and focus on others, or even the addition of senses that (para)humans don’t normally have—a snake’s heat-sensing pits or a bat’s sonar.

Depending upon the nature of the System, a character with a Perception die may have an image link that can display a sort of Heads-Up Display (HUD), along with video, text and images, directly into the view of the character. They may also have the ability to record photos or videos.

  • Digital Zoom: The die step of any Complication or Difficulty die accounting for distance from the visual must exceed the Perception Augs die or the character disregards it. For any such Complication that does apply to the character, step it down by one step.
  • Enhanced Resolution: In a pool containing Perception Augs, replace two dice of equal steps with one die of +1 step.
  • Flash Suppression: The die step of any Complication of Difficulty die accounting for blinding lights must exceed the Perception Augs die or the character disregards it. For any such Complication that does apply to the character, step it down by one step.
  • Enhanced Spectrum Targeting: Add a d6 to your dice pool for an attack against an opponent at near range you cannot see and step back your highest die by one step.
  • Threat Identification: Spend 1PP to add Perception Augs to your pool (or step up by 1 if already in your pool) and reroll all dice on a Reaction.
  • Multispectrum Vision: The die step of any Complication or Difficulty die accounting for poor visibility must exceed the Perception Augs die or the character disregards it. For any such Complication that does apply to the character, step it down by one step.

Reflex: Reflex augs reduce reaction times through increased sensory-processing speed, reduced muscle-response times, and added speed and power for transmissions through the nervous system.

  • Enhanced Fine Motor Control: Spend 1PP to ignore Complication dice applicable to a test involving dexterity.
  • Reaction Enhancement: Step up or double Reflex Augs for a test involving Initiative. Spend 1 PP to do both.
  • Synaptic Acceleration: If a pool includes Reflex Augs, you may replace two dice of an equal size with one die one step higher.

Resilience: Where Athletics Augs cover enhancements to physical endurance, Resilience Augs models systems intended to protect the body from harm, whether from toxins, disease, environmental hazards, or direct physical injury.

  • Subdermal Nanoweave: Your Resilience Aug die (or its equivalent step depending on your damage system) functions as armor against physical attacks.
  • Toxin Filters: In a test to resist toxins, whether airborne, injected, consumed, or otherwise, double or step up Resilience Augs. Spend 1 PP to do both.

Stealth: Stealth systems conceal the user from detection or from identification. This may range from lubrication of joints and the strengthening of muscles and tendons to allow for quieter movement to complex augmentations that allow the user to change the color of their skin, the length of their hair and the shape of their facial features, with various specialized components to provide various kinds of stealth.

Because of the wide variety of possible stealth functions, use of SFX or a solid description of capabilities at various dice steps is essential for this System. For example, if not using SFX: at d6, the System’s focus should be on the avoidance of detection by the senses. At d8, this expands into defenses against sensor detection and perhaps “active camouflage.” At d10, shaping of physical features and appearance becomes possible.

  • Active Camouflage: Spend 1PP to double Stealth Augs against an attempt to detect you visually or by light-spectrum-based sensors.
  • Impersonation Protocols: Step up double Stealth Augs for one scene to mimic a person for whom you have detail information about appearance, physical attributes, habits, vital signs and behaviors. Then, step down Stealth Augs by 1 step. Recover after a scene in which you do not use Stealth Augs.

The Limits of Ascension

You may want to put Limits on these Systems, either to reinforce how Augmentations work in your setting or as a sort of mechanical balance against the SFX (especially if some or all are free) attached to various systems.

Some RPGs separate out different types of augmentation—genetic engineering from cyberware or organic augmentations, for instance. If that is the case in your setting, you may want to use different Limits to represent the specific nature of the augmentations that comprise a particular System. For additional complexity, you could restrict certain SFX to certain classes of augmentation, ruling that a character must choose one Limit when first selecting that System and that, if the character wants to add an SFX that has a Limit related to a different class of augmentation, the character must have both applicable Limits added to the System. So for instance, if a character started with a “wetware”-based System, they would have the corresponding Limit. If that character’s player wanted to add a “cyberware”-based SFX, the Limit related to cyberware would have to be added to the System as well.

For a simpler approach, you could simply assign set Limits to each System, potentially using one or more Limits to offset the automatically-granted SFX associated with the System.

Digression 1
Again, the more complexity you put in this system, the more you need to think about whether the benefit of the added complexity is really worth it. As a concrete example, I started a Cortex Plus/Prime conversion for Shadowrun some time back on this blog (to which I’ll likely return). To capture the feel of Shadowrun, at least the way I’ve approached it, adds a good deal of complexity to the Cortex Prime system, taking it somewhat away from what it was intended to be. Does it end up as complex as Shadowrun? No, but it is substantially more complex than Cortex Prime, and, at that point, it may be worth thinking about whether this is the right system for a conversion, or whether so much of the complexity needs be converted into your Cortex version. With Shadowrun in particular, there already exists a simplified version of the ruleset (called Shadowrun Anarchy) that may fit the bill for you. For me, that system swung the pendulum far too far and ended up with a system that feels inadequate to account for enough complexity to capture the feel of the Shadowrun setting in a streamlined manner.

Digression 2
As best I can tell, in reality, it looks like, by the time human augmentation because truly available, augments will combine both biological and technological aspects of design into a unified whole, making the sorts of distinctions Shadowrun cares about in its treatment of Augmentation a mostly moot point. Of course, there’s a good argument that humans will resort to wearable devices for augmentation rather than surgical intervention (except in the case of prosthetics, injury or lack of natural function, of course), but that’s not quite as fun to imagine, is it? If that suits, though, this mod could be adapted to different Signature Assets to represent that reality.

With those (admittedly characteristic) digressions taken care of, here are some discussions of potential Limits to use with this mod.

Since I’ve already opened the Shadowrun can of worms, let’s start here. There are a few ways to handle Essence as a Limit. The simplest is to add the highest System die to the opposition pool of someone trying to use beneficial magic on the augmented character. For a harsher scenario, add each Augmentation die, or, like Dehumanization below, create a single Complication die based on the steps of the System dice.

If you want to incorporate the idea of lost humanity as well (something I’m personally not a fan of in RPG treatments of augmentation—lookin’ at you Cyberpunk and Shadowrun), then use one of the following: (1) When the first System die reaches d10, the character gains a permanent Complication die at d6 that is added to social tests. For each additional System at D10 or increase to a d12, step up the Complication die. If the Complication die exceeds d12, the character becomes a cyberzombie. Adjust the die step at which the Complication comes into play or is stepped up to suit; or (2) Simply add any System die at d12 to the opposition on social tests.

A few options here:

  • A character with this Limit may have Stress or Trauma to both physical and mental tracks caused by hacking attack;
  • Hacking may be used against this character to create Complications or Conditions;
  • A System with this Limit may be stepped down like an Asset or Complication through the use of hacking. You’ll need to choose a method by which the die is recovered;
  • If you have a specific Stress/Trauma track for Augmentations or being hacked, you could tie steps down or shutdown of Systems dice to that; or
  • Some combination of the above.

Complex Biology
Add the highest System die to the opposition against tests to recover or heal from damage through medical intervention.

EMP Vulnerability
This could likewise be modeled several ways:

  • EMP devices that affect this character can apply Complications or Conditions;
  • A System with this Limit may be stepped down like an Asset or Complication through exposure to electromagnetic interference. You’ll need to choose a method by which the die is recovered;
  • When exposed to electromagnetic interference, shut down this System to gain 1 PP;
  • Some combination of the above.

Conscious Activation
As written.

Glitchy/Prototype/Bleeding Edge
Convert the System die to a Complication for a roll to gain 1 PP.

Systems Stress

You may want to consider giving characters a Systems Stress Track, particularly if using rules for Stress/Trauma Tracks like those I mentioned in my series on adding grit to Cortex Prime. If you do, a few additional options may open up to you. For one, you get a way to track the condition of Systems, whether they’re affected by overuse, by hacking, by electromagnetic interference, or some other factor. If the Systems Stress Track is filled, you lose access to Systems dice. You can set up Complication/Condition dice for various stages along the Track and/or step down all Systems dice at various points along the Track, depending on the effects you want to achieve. As an additional benefit, you can allow characters to “push” their augmentations, activating associated SFX, by adding a point of Stress to the Systems Stress Track in lieu of paying a PP. In such a case, you can allow a PP to be spent as usual, or, if you want a “push your luck” sort of system with augmentations, you can require Systems Stress to be used to activate augmentation SFX. If you choose this path, you’ll have to determine how Systems Stress is recovered.


So there you have it, a system for handling (para)human augmentation in the Cortex System without resorting to the Powers/Abilities given in the core game. I’ve tried to include enough options in my write-up to let you fine-tune this system to suit your particular setting. I’d love to hear your thoughts on all of this, see the additional SFX you add to your lists, and generally hear about how the system works out for you if you use it!
