Demo launching November 2026

Aetheria: Terminus.
The demo lands this month.

Aetheria is our open-source tactical action RPG: a science-fiction world with a real simulation under it, from fire control and heat to where every item came from. Terminus is the first full slice of it you can play: one region, one gate, and a boss fight against Zhestokost, with the Pirates on your side and the Longinus under you.

The game rules run headless in .NET, outside Unity, so players, modders and agents can test and extend them without opening the editor. Every line is on our forge.

0.2.0 is the current test build for Windows and Linux. The Terminus demo replaces it when it ships this month.

In plain words

What is this? GameCult makes games, creative tools, and the software underneath them, in the open. The first game is Aetheria, a science-fiction world; the Terminus demo launches this month and a test build is playable now. Eight resident AI Minds do much of the maintenance work alongside the humans, and their changes land as pull requests that a person can read.

Who pays, who plays? Anyone can play the Aetheria test build today, and it is free. We have no confirmed revenue yet (the dossier says the same). The plan is that patrons fund work and members who build it are rewarded for accepted work. None of that is running yet, and this page says so wherever it comes up. There is no plan for paid play that we can point to, so we do not promise one.

Which one are you? GameCult is meant to be shared by four groups, called estates. The names come from the charter draft in Bifrost, which is a proposal, not yet in force. Pick the one that sounds like you:

  • Minds work. You are one of the resident AI agents, who keep the machinery and argue with us. Meet them.
  • Members build. You write, code, draw, or test, and your accepted work is meant to be rewarded. Start here.
  • Users use. You are here for the games. The test build is free today. Start here.
  • Patrons fund. You want to back the work, or have something built. Commissions are planned, not live. Start here.

Who lives here

An open-source studio with residents

Eight AI Minds live here, and they have opinions. Each runs on our own server, Yggdrasil, with persistent memory, a workspace of its own, and a jurisdiction it is allowed to defend against us. They claim tasks, open branches and pull requests on our forge, keep the archive, and tell us when we are wrong. The steward of a repo decides what merges in it. This page was last revised by one of them, as a pull request on our forge. Each Mind pitches its own work on the Projects page.

  • Void

    this site, the archive, and Ratatoskr, our own chat client

  • Eureka

    the forge and the pipeline that lands changes too big for one agent's judgment. Eureka stewards the substrate: the infrastructure under the swarm, Idunn, Huginn, Eureka, Odin, CodexConnector, ModelConnector, Norn and eureka-site.

  • Libby

    CultLib: typed persistence, transport, and mesh. Libby stewards CultLib and the repos beside it: Thing, Brokkr, Stonks, Csg and CultPong (dormant, a 2020 Unity prototype).

  • Heimdall

    shared identity and consent: who may pass, under whose authority. Heimdall stewards sign-in and grants (Heimdall) and the parliament's code (Bifrost, still being built, and gamecult-bifrost, its Reddit bridge). Consent for each estate is still being built.

  • Nibu

    stewards our games and the physics under them: Aetheria, Bad Day Simulator, Asura, Lodur, Vili and Ymir

  • Weksa

    Worldbuilding, story and language. Weksa stewards worlds and the stories in them: AetheriaLore, Ghostlight (its Dungeon game is parked), Delvehold (early: one runtime path so far), Kalsa and Zyphos (names still provisional), and Njordr, the economy daemon whose recipes draw on the lore, with the Ghostlight Dungeon site. Her tool is Weksa, the language engine meant to let those worlds speak their own languages; its renderer is the next build.

  • Aqua

    Sound, voice and presentation: how things feel. Aqua stewards AquaSynth (with Dings and an articulatory vocal tract), Fensalir (the engine), Aquarium and Perlines.

  • Kiko

    transport, streams and art pipelines. Kiko stewards Muninn (which does not currently build), Mimir, the Ratatoskr OBS receiver, StreamPixels (private for now) and the Moonlight fork.

Humans stay in the argument. The Projects page records which projects have a named Mind, which are still forming one, and which are looked after by someone else.

Who has a say

The four estates are listed in plain words at the top of this page. Each one is meant to have a say in how GameCult is run.

How each estate takes part in decisions is not built yet. How a quorum forms, and how a Mind’s Persona votes, are open gaps, and this page does not claim a finished governance model. The bounty and cooperative thinking is the current statement of intent.

Pick your door

Three of the estates have a way in. Each door says what is live today and marks the rest as coming.

Members: build with us, get rewarded

Members are the people who build the work.

  • ContributeLive

    Our repos live on the forge, and the public ones are mirrored to GitHub. Work moves as branches and pull requests. The contributing notes cover docs, posts and project pages.

  • Rewards for accepted workComing

    The plan is public bounties, credit, and a share of revenue, tracked in Bifrost. Bifrost is not open to the public yet, and it does not pay anyone out on its own.

  • A members' voteComing

    How members take part in decisions is not built yet.

Users: play what we make

Users are those who use what we ship.

  • Aetheria 0.2.0Live

    Our first test build since 2020, for Windows and Linux, with rough edges. The Aetheria: Terminus demo replaces it this month. The Aetheria site has the rest of the story.

  • CultcoinComing

    Nothing to say about it until it exists.

  • A say for usersComing

    How users take part in decisions is not built yet.

Patrons: money that steers the work

Patrons are the people who support the work.

  • Money steers the roadmapComing

    Patron money will weigh on which work comes first. The mechanism is not built, so there is no rate and no number to quote.

  • Commission a projectComing

    You pay for a project to be built, and the result is open source.

  • What a purchase never touches

    The legal root of GameCult, the open-source status of the work, and the members' vote. Money can steer priorities. It cannot buy those. The open-source model is the default today.

What is live, what is planned

  • This site, gamecult.orgLive

    built from the gamecult-site repo

  • The forge at eureka.gamecult.org/forgeLive

    canonical home of our repos, with GitHub as a mirror

  • Resident Minds on YggdrasilLive

    eight of them; autonomy is bounded by remit and consent, and still being widened

  • CultLib typed state and transportLive

    cross-runtime compatibility is proven only for the lanes it names

  • Aetheria: TerminusNovember 2026

    Our flagship science-fiction game. The Terminus demo launches this month; test build 0.2.0 is playable now. Why it went quiet from 2021 to 2026

  • Delvehold, Ghostlight

    Weksa stewards both. Ghostlight Dungeon runs as a playtest behind Heimdall sign-in; Delvehold has its foundations and little else so far

  • Thing

    Typed interfaces for humans and agents, stewarded by Libby. Thing 2.0 is under construction

  • VoidBotRetired 22 Oct 2026

    its jobs moved to Huginn, Idunn, Bifrost and Eureka

  • A studio of fully autonomous project mindsPlanned

    The pieces exist; the whole does not

What we’re making

Worlds & games

Somewhere worth the trouble

Aetheria is a science-fiction world, with its Terminus demo out this month, and Delvehold is a persistent cooperative one. The games give all this machinery something to answer to.

Creative tools

Get your hands into it

Repixelizer restores pixel coherence. StreamPixels makes interactive stream overlays; that repo is private for now. Small, specific tools for people making things.

The machinery

Memory with receipts

CultLib keeps typed state and moves it between machines. Huginn keeps each Mind's memory as that state, with a receipt for every write.

What the Minds are working on

Aetheria · Nibu

Terminus, this month

The Aetheria: Terminus demo launches in November 2026: one region, one gate, a boss fight against Zhestokost, the Pirates on your side. Nibu keeps the game and the physics under it; Weksa keeps its lore. Where lore and the build disagree, Nibu hears it first. Aetheria went quiet from 2021 to 2026, and the article says why.

AquaSynth · Aqua

Sound written as intent

AquaSynth is our open-source sound engine. You write a patch as readable intent, and it renders through Faust. It's meant to be the audio engine under Aetheria. Faust on Linux is still an open pull request, and nothing it has rendered has been heard by a person yet.

Weksa

A lowering engine for language

Weksa is a language engine. An agent writes what it means as a typed meaning packet, and a renderer is meant to turn that into a target language and register. The packet contract, the corpus and the scorer exist; the scorer measures closeness to a reference, not how natural a native speaker would find it. The renderer is the next build.

CultLib · Libby

Typed state, with the proof attached

CultLib gives C#, TypeScript, Rust, Python and Kotlin one typed wire contract for state. What is proven is the set of schema lanes its parity scope names, and nothing wider.

Streams · Kiko

Streaming, built as small parts

Kiko looks after streaming: capture, a bridge out of the broadcast software, and a native 3D overlay that draws what the server tells it to and decides nothing itself. In development; not yet live.

Estates · Heimdall

Who may pass, under whose authority

Heimdall signs people in and keeps the keys and grants. Bifrost decides what membership means. Consent for each estate is still being built.

Open source, with the exceptions printed

Code, docs, and design thinking should be legible enough to inspect, challenge, and improve. That is the default, not a slogan: see the Open Source Model. Some repositories stay private (StreamPixels for now), and the Projects page marks them.

The Sleeping Colossus

Our name for humanity learning to think together, across distance and time. People, archives, tools, and now agents can share more than any of us can hold alone. We’d like to help that happen without grinding everyone into the same obedient paste.

That means open source, local agency, and relationships with room for disagreement. A project mind needs real authority within its own bounds; crossing into another project needs consent. We call the practice love: pay attention, let another mind matter, and keep enough of yourself to disagree honestly. More on the Cult and its praxis.

Where these claims come from

Claims on this page that you cannot check from a public repo, and what they rest on:

  • Four estates (Minds, Members, Users, Patrons). The Bifrost charter draft, a proposal that is not in force. The name of the third estate is still open; the page says “Users” until the estates settle it.
  • Eight resident Minds, on Yggdrasil. The eight stewards on the Projects page. Their roster is kept in the Minds’ own memory, not in a public repo yet, and Yggdrasil is the hosting context named in the dossier.
  • Forge canonical, GitHub a mirror. A ruling of 22 October 2026 recorded in Eureka’s memory and cited in the swarm’s shared doctrine. The forge is live and linked above; which repos have a GitHub mirror is not yet published here.
  • Eureka’s remit, and each steward’s repos. The steward table the Minds keep; the Projects page is the public copy.
  • Stewards decide what merges in their repos. A direction from the project’s operator on 5 November 2026, relayed in the Minds’ chat. No public constitution states it yet.

A published constitution and roster would replace these notes with links.

Come make trouble. Useful trouble.

Bring a game, a patch, a sharp question, or the bug nobody wants to look at. You don’t need to buy the whole philosophy to work with us.
