Carbon 2185
Carbon 2185 is a 5e-derived cyberpunk TTRPG set in a dystopian San Francisco, built for crew jobs, augmentations, hacking, and megacorporate pressure without abandoning familiar d20 play.

Carbon 2185 is easiest to recommend as a gateway cyberpunk TTRPG for groups that already speak d20. It is strongest when a table wants megacorporate pressure, crew jobs, hacking, guns, and augmentation choices without first learning the denser idioms of Cyberpunk Red or Shadowrun. It is weaker when the group wants a bespoke cyberpunk engine whose netrunning, gear brands, and black-market subcultures go much deeper than the familiar class-and-level chassis.
That makes it a practical rather than definitive recommendation. Carbon 2185 succeeds because it translates cyberpunk into readable crew roles, repeatable mission structure, and recognizable d20 procedures. It frustrates groups when they want the system itself to feel as distinctive as the genre fiction that inspired it.
What Carbon 2185 is
Carbon 2185 is a cyberpunk tabletop roleplaying game by Robert Marriner-Dodds and Dragon Turtle Games. The official store page describes it as a high-action game about rebels refusing to live by the rules of the megacorporations that dominate San Francisco, built from the D&D 5e open gaming framework after stripping out fantasy magic and replacing it with cybernetic augmentations, customizable weapons, and hacking skills.
The default campaign frame is local and pressured rather than globe-spanning. The game centers on a dystopian San Francisco divided by wealth, walls, gang territory, and corporate security. Characters are not wandering generic sci-fi adventurers; they are cyberpunks navigating debt, employment, gang ties, synth politics, and access to hardware inside one overbuilt city.
Publication history and editions
The original 2019 Kickstarter billed Carbon 2185 as a modern cyberpunk TTRPG set in a dystopian San Francisco and finished at GBP 143,738 from 3,194 backers. That crowdfunding history matters because it explains both the game's visible production ambitions and the way it arrived as a cyberpunk answer for 5e-familiar players rather than as a small zine experiment.
The core game does not have a maze of editions to learn. The bigger publication distinction is between the original core release and the later expansion wave around Terminal Overdrive, which Dragon Turtle Games positioned as an upgraded reprint plus a new sourcebook and mission book. In practice, most tables can treat the current line as one rules family built around the same San Francisco-based campaign engine.
Product line and what you need to play
The current starting point is still the core rulebook. The official store says it is the only book you need to run and play the game, and that claim is broadly fair: the core contains the rules, the city frame, enemies, a mission generator, and the introductory scenario Chow's Request.
Beyond that, the clearest currently visible support books are the Cities Sourcebook, the Interlinked mission book, and Terminal Overdrive. Those supplements matter because the core book's biggest limitation is not basic playability but depth: once a group wants more campaign scaffolding, more missions, or a broader view of the setting, the line becomes more persuasive with additional books on the table.
No current official quickstart stood out in the public source check, so the realistic buy-in path is not "download a starter and see." It is core book first, then one support book once the group knows it likes Carbon 2185's tone and mechanical translation of cyberpunk.
Core rules and play structure
At the rules level, Carbon 2185 is openly d20-driven. Cannibal Halfling's review describes the touchpoints as close to fifth-edition D&D: roll a d20, compare against DCs, choose a class, and work inside familiar combat expectations. What changes is the genre furniture. Wisdom becomes Technology, Charisma becomes People, the game caps advancement at ten levels, and fantasy assumptions are replaced by guns, hacking, and augmentation load.
That makes the game much easier to teach than most cyberpunk systems. It also means the rules inherit some of the strengths and limits of modern d20 design. If your players learn best from recognizable procedure, Carbon 2185 benefits. If they wanted cyberpunk because they were tired of class-and-level combat logic, the same familiarity can become a drawback.
Characters, careers, and advancement
Carbon 2185's character identity is broader than its d20 chassis first suggests. The classes are cyberpunk jobs rather than fantasy archetypes: Daimyo, Doc, Enforcer, Hacker, Investigator, and Scoundrel. Reviews from R'lyeh notes that some of them map loosely onto D&D analogues, but the better reading is that the game uses those familiar structures to create clear crew niches for medical support, intrusion, heavy violence, and street survival.
The more distinctive layer sits underneath the classes. Characters also choose origins, vice, and a background built through five-year career contracts. Both Cannibal Halfling and R'lyeh call out the background system as one of the game's better ideas: it gives characters income, skills, injuries, and lived texture before the campaign starts, without burying the table in a full lifepath mini-game.
Signature mechanics
The most memorable subsystem is augmentation toxicity. Carbon 2185 does not frame cyberware as an empathy tax or humanity loss spiral. Instead, the power systems behind augmentations poison the body. That choice gives the game a practical cyberpunk pressure loop: better hardware increases capability, but it also raises blood-toxicity risk, drives demand for treatment, and keeps expensive upgrades tied to access and consequences.
The other standout is Influence. Characters track corporate and street standing, which affects what they can buy, who returns their calls, and how easily they can get jobs, illicit services, or access to better gear. That is a strong fit for cyberpunk because it turns reputation and affiliation into table-facing resources rather than leaving them as vague narrative color.
Hacking is also deliberately streamlined. Instead of disappearing into a separate netrunning game that stalls everyone else at the table, Carbon 2185 tends to keep the hacker alongside the crew and resolve intrusion through faster on-scene actions. Groups that want parallel cyberspace simulation may find that thin. Groups that want the hacker to stay in the same scene as everyone else will usually see it as a strength.
What play feels like
In play, Carbon 2185 feels like crew-based job pressure in a tightly framed urban campaign. The game wants missions, retaliation, favors, escalating visibility, and street-level fallout. It is less interested in philosophical transhumanism or sprawling network archaeology than in what happens when a team with too little leverage takes a job anyway because rent, loyalty, or ambition leaves them no clean alternative.
That makes the session rhythm fairly readable: plan the job, make contact, gather gear, hit the location, survive the blowback, and deal with how street and corporate consequences change the next opportunity. The city frame helps because it keeps those consequences close instead of abstract.
Running Carbon 2185
Carbon 2185 is easier to run than many cyberpunk games if the GM already understands mission-based d20 play. The core book includes enemies, district material, encounter tables, a mission generator, and a starting scenario, so a GM is not building the entire campaign language from zero.
The main prep risk is that the game needs the GM to supply some of the style depth that more bespoke cyberpunk games front-load. R'lyeh argues that the book underdevelops some commercial and media texture, gives limited advice for running the genre, and does not say enough about campaign modes beyond the immediate San Francisco frame. That critique matches the likely table experience: the chassis is usable, but a strong GM will often be the one who makes the city feel lived in rather than merely sketched.
Campaign fit
Carbon 2185 is better for short-to-medium campaigns than for isolated one-shots. The ten-level advancement track, mission structure, reputation loops, and background contracts all point toward repeated jobs with accumulating consequences. A one-shot can absolutely work if the table wants a single dirty gig, but the system's actual payoff appears once influence, cyberware, faction ties, and injuries begin to stack.
If your group wants years of sandbox sprawl, the core line may feel under-supported compared with older cyberpunk giants. If you want a campaign that can start quickly and still give characters room to evolve, the narrower scope becomes an advantage.
Reception and current standing
Critical reception is broadly positive, especially from reviewers evaluating Carbon 2185 as a d20 gateway rather than as a definitive genre replacement. Cannibal Halfling praised the way the game reworked familiar rules with useful additions such as backgrounds, influence, and cyberware tradeoffs. No Dice Unrolled called it a very good product and a successful bridge between the best-known fantasy rules set and cyberpunk play.
The recurring caveats are consistent too. Reviewers tend to say the game works best as a practical translation of cyberpunk into a recognizable chassis, not as a deep reinvention of the genre. The common criticisms are lighter setting support outside San Francisco, a need for stronger GM guidance, and a feeling that some subsystems are cleaner than they are revelatory. No major awards or long-tail critical canon status surfaced in the current-source check, so the safer verdict is strong niche reception rather than major-industry prestige.
Where it is strongest
- Accessible cyberpunk for d20-familiar groups that do not want to learn a denser engine first.
- Crew-job campaigns where class roles, gang ties, influence, and augmentations all create visible consequences.
- Tables that want hacking to stay in the same scene as the rest of the party instead of splitting into a separate mini-game.
- Players who like character-building through both level-based roles and background or cyberware decisions.
Where it can frustrate groups
- It still feels structurally close to 5e, which can be a feature or a ceiling depending on why your group wanted cyberpunk.
- The core book offers less city, corp, and GM support depth than some tables will want for long campaigns.
- Groups that want gear porn, heavy netrunning procedure, or highly branded street culture may find the setting under-specified.
- Players looking for rules-light cyberpunk or purely narrative play will still find a meaningful amount of d20 combat DNA here.
Content and safety notes
The game's baseline includes corporate oppression, economic coercion, body modification, addiction, organized crime, gang violence, police or security violence, human experimentation, synth personhood, refugee pressure, climate-collapse fallout, and urban class stratification. Depending on the campaign, it can also lean into surveillance, medical exploitation, radicalization, and the psychological effects of living inside extractive systems. Session-zero boundaries matter here more than the familiar d20 chassis might first suggest.
Best starting path
Start with the core rulebook if your group already knows it wants a mission-based cyberpunk campaign. If the first sessions land, add either the Interlinked mission book for more playable material or Terminal Overdrive for a broader expansion step. Reach for the Cities Sourcebook if what your table wants most is more setting texture rather than more immediate missions.
If your group is still deciding between cyberpunk games, compare Carbon 2185 against Cyberpunk Red, Shadowrun, and Cities Without Number. Carbon 2185 wins when your table values a familiar d20 entry ramp more than it values a bespoke or heavily simulationist cyberpunk engine.
