Altered Carbon as a campaign world


Those that have not watched this Netflix series should stop reading this now and watch it.. While I am going to avoid discussing the plot directly, some of the technology and its implications may in fact act as spoilers, so leave now. I’ll wait.

The basic premise of the AC world is that through alien technology mankind can digitize their consciousness. This allows the following:

Consciousness can be transferred from body to body - referred to as Sleeves and is contained within Magic Alien devices called Stacks. These Stacks are durable, but not indestructible.

Consciousness can be transferred between planets again via alien technology, so interstellar travel without FTL ships is possible. It is possible to upload your consciousness though the equivalent of the internet locally as well. You do, of course, need to have a sleeve waiting and ready for you there.

You can have backups taken of your consciousness, though apparently this is ruinously expensive and considered the domain of the Meths( From Methuselah) stupid rich and powerful elite who can essentially live eternally by sleeve replacement. You can have more than one 'active' copy of your consciousness as well, though this is considered to be a High crime punishable by True Death - destruction of all of one's stacks.

Weapon Tech

Standard Science Fiction here. We have good old slugthrowers, Gauss pistols/rifles, flechettes, lasers, particle pistols, etc. No lightsabers that I have seen, but vibro weapons would not be out of place.


Seem to be about Star Wars tech level. Shuttles can take off from small launch pads without immolating acres of space and reach orbit. Flying cars are commonplace. Starships are present, but are superceded by Needlecasting (Long distance transmission of one's consciousness into a new sleeve)


Cloning exists, big time, along with the ability to 3D print clones. Presumably growing clones is cheaper than printing them, but would require much more time.


Normal humans, Transhumans and Freaks are all present. ‘Sleeves’ can be genetically modified to have upgrades to them, people can get upgraded sleeves if they can afford them or are rewarded by those who can.

Genetic freaks are also created, some for gladiator style games. These can resemble standard fantasy races if desired, but really with the level of tech in this world, just about anything is possible.

It is apparently possible to be resleeved in non-human bodies though it does not appear to take well in the few examples presented in the show. It could be presumed that any creature with sufficient brain power could be used as a sheath. It was not touched on on the series, but it could be possible for humans to transfer their stack to an Alien sheath. It works in the reverse.

Transhuman sleeves could be a later campaign option for players. Freaks could be available at the start, with the standard caveat that they would be treated poorly in that form.


AIs could play a part as well, at the very least as supporting characters. However, while it has not appeared in the series so far, I don’t see why an AI could not become resident in a stack and ‘become’ human.


The Precursors. Angel-like (in an Aliens-ish kind of way) with very high tech levels. While they do interact in the series, they do so in a very singular way that would preclude their inclusion in a lower profile campaign. They are a good source of super powered alien artifacts - such as the stacks, and dormant(?) orbital defense systems.


Due to the existence of cloning and 3D printed body parts, medical intervention is extremely powerful, with the final option of simply removing the Stack and obtaining though some means a new Sleeve. Short of that - especially if resleeving is not an option due to religious/ethical grounds, there are very good cybernetics which run the gamut from pure mechanical to blended bioengineered/mechanical. The limits are mainly on how much money the victim (or their associates) have.


You’ve got megacities, Archaeologies, private islands, other planets, orbital facilities,etc. Its wide open. But of course Money is all important, and corruption is everywhere. With enough money, you can have clones spread around the galaxy and then Needle Cast yourself into one of these.


Staying away from the show's plot lines, it should be clear that there are lots of options. There is the perpetual battle between the haves and have-nots, religious conflicts, anti-stack technology terrorists, political unrest, etc. Its really a pretty wide open world for gaming if you don't really want to follow the

General Notes

When gaming in this world it would make sense to clearly delineate your mental abilities, which transfer unaltered from sleeve to sleeve, and to physical abilities which are sleeve specific.

Sleeves can be easy, they can be short lived. Your character gets shot up beyond repair? Just grab one of your enemies’ sleeves and steal it. You get that sleeve’s baggage, at least until everyone learns you’ve been resleeved. PCs get lots of money? They can buy a backup sleeve and then pay for maintenance. Just like a lich’s amulet, it needs to be protected. Stop paying? Well, the backup company will just format the sleeve and use it for another customer.

Want to play a second character? Clone yourself and copy your stack - and hope you don’t get caught.

Game Systems

Based on my own experiences, Shadowrun and Spacemaster (especially with Cyberspace added) would seem to be good fits at different ends of the complexity spectrum. Perhaps even old school Star Wars D6 could work

In all, I found it a very interesting series, and think it would make for some great roleplaying!

? Quest

When you are under siege, you have nothing but time. But the abundance of time is just as much of a weight as the enemy outside the gates. It is time for the Citadel to develop a creative Stimulus Package to support the Strolenati during this unique time. After no deliberation and no votes, the following will be the procedures followed through the the Citadel Stimulus Quest. (Subject to change, amendment, and adjustment as needed.)

  • Every Monday a minimum influx of $40 will be added to the Stimulus Package to keep the Creative Citadel Economy out of a Recession.
  • The Stimulus Package will accumulate $40 weekly until there are 5 unique author submissions.
  • Authors can write as many submissions as they like and each will be considered on their own merits.
  • On the Sunday after the 5 author requirement is met, the 5+ submissions by 5+ authors will be weighed and measured by the Strolenati.
  • Whomever is determined as the winner(s) will receive funds (as determined by the Strolenati) that have collected in the Stimulus Package.
  • On Monday, if winners were awarded, the Stimulus Package will be re-established at $40 and the quest will restart.
  • The quest will continue in this cycle until such a time that the Strolenati Council has deemed the siege over.
Current Stimulus Package: $40
Next Update: Jul 13

Round 1 completed May 10: 7 Weeks - $280 in Stimulus reserves. Since it was the first round, and the amount was enough to pass around, we decided everyone who took the time deserved something. So sayeth the Strolenati.

Round 2 completed July 6: 8 Weeks - $340 in Stimulus reserves. Incresed funding and a stabilized creative force has allowed some increases in most awards. So sayeth the Strolenati.
