A little water. A whole world. |
Raise a neon skyline. Keep the grid alive. |
Found an adobe city beside a wandering spring. Bring water and shade to its districts, trade with caravans and adapt to sandstorms. |
Build under pressure from an unstable grid, megacorporations and hackers. Connect the city, grow its skyline and keep its networks running. |
|
You set the conditions. The city decides the rest. |
Build, explore and fight — when you want to. |
Lay roads, zone districts and keep power and water flowing. Watch demand, traffic and disasters shape the city you started. |
Explore a voxel world in Adventure or OneBlock mode. Build freely, craft your next tool and seek out optional bosses when you're ready. |
Real gameplay from the projects. Sítio, Urbe, Neo Urbe and Urbe Oasis support English, Portuguese, Spanish, French and German. MineBoss currently has a Portuguese player interface.
Plot 42 is the studio's collection of small browser games:
- Horta — plant, wait and harvest on a small isometric plot.
- Posto — command three units in turn-based combat on a compact board.
- Mata — restore a landscape before drought takes over.
Its lobby also connects you to the standalone Urbe and Neo Urbe sites.

We build games around systems you can explore: a coffee farm becoming a village, a growing city, a fragile water supply, a world made of blocks, a city held together by squads and supply lines. The same curiosity that makes them fun to play makes them interesting to take apart.
- Start with a browser tab. The featured games are free to play, with no installation required.
- Look inside. Each featured game has public source code under its own license; check its repository for code, asset and dependency terms. Read how a mechanic works, change the rules or build your own variation.
- Build in the open. Follow commits, report what you find and help shape the next change.
The featured projects use TypeScript, with PixiJS for the Urbe games and Three.js for MineBoss and Vazante. Sítio and Vazante combine a React interface with a deterministic simulation in a Web Worker. The Urbe city simulations run in a Web Worker, keeping simulation work separate from the interface.
We welcome open-source games, engines, frameworks, libraries, SDKs, development tools and AI agents for games, on any engine or platform. Bring working software or an early implementation ready for incubation; source code must already exist.
- Shared maintenance: stay involved as a maintainer and build with other contributors.
- Community adoption: propose a handover so new maintainers can continue the project. Proposals can wait for interested volunteers.
After approval, the project gains a repository in the organization, public issues and PRs, and a shared home for documentation and continuity. Authors, credits and history are preserved. At least one responsible maintainer must be confirmed before a repository joins. Hosting does not guarantee funding, a dedicated team, support deadlines or permanent maintenance; promotion in the studio catalog is evaluated separately.
How it works: submit a public proposal → review with the organization → resolve entry criteria and confirm maintainers → record the decision → coordinate an approved transfer or history-preserving import.
Preferred license defaults by category: complete game code, game servers and multiplayer infrastructure prioritize AGPL-3.0-or-later; engines, frameworks, libraries, SDKs, development tools and AI agents for games prioritize Apache-2.0. Documentation uses CC-BY-4.0; 2D/3D assets use CC-BY-4.0 or CC-BY-SA-4.0; music and sound use CC0-1.0 or CC-BY-4.0. Code, documentation and resource licenses remain explicit and separate. Existing licenses and exceptions are reviewed case by case, and third-party resources retain their applicable licenses.
AGPL is the default across platforms, including offline games. Distribution through stores or consoles requires a compatibility review of platform terms, dependencies and source-delivery requirements; availability on every platform is not guaranteed. Projects under MIT, BSD, GPL or other open-source licenses are also welcome for evaluation. We consider the project's goals, community, dependencies and distribution channels. The chosen license and the rationale for exceptions must be documented and approved by the organization before acceptance. Joining does not require automatic relicensing.
Current organization repositories keep their existing licenses, including MIT where already used. Any migration of the existing collection will be evaluated separately, project by project, with the relevant rights holders and dependencies considered; no migration is automatic.

Inspired by the OCA's public collaboration, identified maintainers and project maturation, adapted to an independent game-development community.
Open source can support paid, ongoing work. We want Game Studio 42 to be sustainable for its creator and maintainers through two complementary paths:
- Recurring sponsorship: support the creator's development and maintenance work, or a specific community project through its own identified funding channel.
- Paid services: discuss custom game development, adaptations, integrations and contracted support. Availability, scope, price and delivery terms must be agreed before work starts.
Each funding channel must identify who receives the funds and what they support. Support for an individual maintainer is not an organization-wide fund or an automatic distribution to every project. Community participation does not transfer authorship or create an automatic revenue-sharing arrangement; any commercial collaboration needs a separate agreement with the people involved.
Sponsorship is voluntary and does not purchase project acceptance, governance rights or guaranteed delivery. The currently featured browser games remain free to play. Paid services are optional and do not restrict the rights granted by each project's license.
Talk about services or sponsorship: [email protected].
GitHub Sponsors for the gamestudio42 organization is being prepared. A Patreon is also under consideration. Payment links will be published once the channels are active, with their recipient and purpose clearly identified.
A good contribution can start with a play session, a clear bug report, a translation, a better sprite or a change to the simulation.
- Pick a project. Use its README for setup instructions, controls and development commands.
- Find something worth improving. Browse open issues or look for good first issues. For a larger change, discuss the idea in that project's issues first.
- Make it easy to review. Describe the change, include reproduction steps or screenshots where useful, and run the checks documented by the project.
To explore Urbe locally, with Git, Node.js and pnpm installed:
git clone https://github.com/gamestudio42/urbe.git
cd urbe
pnpm install
pnpm devSee Urbe's development guide for setup and checks. Each project documents its own runtime requirements and deployment steps. If you publish a fork, retain the required license notices and review the project's asset licenses.
Prefer to play? Useful feedback matters too. Tell us what you tried, what happened and what you expected. Include your browser, game mode and reproduction steps when reporting a bug.

Trabalho aberto e sustentável. Queremos sustentar o trabalho do criador e dos mantenedores com apoio recorrente e serviços pagos de desenvolvimento, personalização, integração e suporte contratado. Cada canal de apoio deve identificar seu beneficiário e sua finalidade; apoiar um mantenedor não significa financiar todos os projetos. Serviços dependem de disponibilidade e acordo de escopo, preço e prazo. Participar da comunidade não transfere autoria nem cria divisão automática de receitas. Patrocínio não compra acolhimento ou poder de decisão.

Un travail ouvert et durable. Nous souhaitons soutenir le travail du créateur et des responsables des projets par un soutien récurrent et des prestations payantes : développement, adaptation, intégration et assistance contractuelle. Chaque canal doit préciser son bénéficiaire et son objet ; soutenir une personne ne finance pas automatiquement tous les projets. Les prestations dépendent des disponibilités et d'un accord sur le périmètre, le prix et les délais. Participer ne transfère pas la paternité et ne crée pas de partage automatique des revenus. Le soutien financier n'achète ni l'accueil d'un projet ni des droits de décision.
Parlons de prestations ou de soutien financier : [email protected].
GitHub Sponsors est en préparation pour l’organisation gamestudio42. Patreon est également à l’étude. Les liens seront publiés une fois les canaux actifs, avec leur bénéficiaire et leur objet.

Die drei Urbe-Spiele bieten fünf Sprachen. Die Oberfläche von MineBoss ist auf Portugiesisch. Jedes Projekt behält seine eigene Lizenz. Sítio verwendet AGPL-3.0-or-later für das Spiel, Apache-2.0 für wiederverwendbare Bibliotheken und CC-BY-4.0 für Grafik und Dokumentation; neue Projekte folgen den Vorgaben je Kategorie, ohne automatische Lizenzänderung bestehender Projekte.
Dein Projekt kann mit der Game Studio 42 Community wachsen. Wir begrüßen Spiele, Engines, Frameworks, Bibliotheken, SDKs, Entwicklungswerkzeuge und KI-Agenten für Spiele, unabhängig von Engine oder Plattform. Möglich sind gemeinsame Wartung und Übernahme durch die Community. Frühe Projekte mit vorhandenem Code können in die Inkubation aufgenommen werden; vorher muss eine verantwortliche Person bestätigt sein. AGPL und Apache sind die bevorzugten Standards; Projekte unter MIT, BSD, GPL oder anderen Open-Source-Lizenzen können ebenfalls nach Prüfung aufgenommen werden. Auswahl und Ausnahmen werden begründet und dokumentiert, ohne automatische Lizenzänderung und mit erhaltenen Urheberangaben. Bestehende Repository-Lizenzen bleiben erhalten; die Aufnahme in den Spielekatalog wird gesondert geprüft.

Offene Entwicklung, nachhaltige Arbeit. Wir möchten die Arbeit des Gründers und der Maintainer durch regelmäßige Unterstützung und bezahlte Leistungen finanzieren: Entwicklung, Anpassung, Integration und vertraglichen Support. Jeder Finanzierungskanal muss Empfänger und Zweck nennen; die Unterstützung einer Person finanziert nicht automatisch alle Projekte. Leistungen setzen Verfügbarkeit und eine Vereinbarung über Umfang, Preis und Termine voraus. Die Teilnahme überträgt keine Urheberschaft und begründet keine automatische Umsatzbeteiligung. Sponsoring erkauft weder die Aufnahme eines Projekts noch Entscheidungsrechte.
Kontakt für Leistungen oder Sponsoring: [email protected].
