Setup and Getting Started

Athena Crisis is built with a modern JavaScript toolchain and a monorepo structure designed to support both the client and server sides of the game. To get started locally, you’ll need:

• Node.js: A current, actively maintained version of Node.js.
• pnpm: The latest major version of pnpm for fast, reliable package management.

For Windows users, there are a few platform-specific tips to ensure a smooth setup. If you prefer a bash-like shell for script execution, you can configure npm to use Git Bash by default. A typical recommended setup sequence includes:

• npm config set script-shell "C:\Program Files\git\bin\bash.exe"
• pnpm install && pnpm dev:setup
• pnpm dev:docs

After installation, you can open http://localhost:3003/ to view the docs page and explore the Playground and documentation in an interactive way.

Documentation and Playground

Athena Crisis ships with a thoughtful documentation and playground site that helps you understand not just how to run the project, but how the different parts of the codebase fit together. The Documentation & Playground hub serves as a living guide, showing how to navigate a complex, multi-package repository and how to experiment with the engine, the map data, and the AI.

• The Documentation & Playground site is a central portal for exploration, testing ideas, and reading about internal data structures, algorithms, and rendering pipelines.
• It provides an end-to-end overview of how data flows from map state and game state to rendering and AI decisions.

Package Architecture: Core and Secondary Domains

The codebase is organized into a set of packages designed to enforce separation of concerns and to encourage reuse and collaboration. The core packages are the scaffolding that make a turn-based strategy engine both powerful and approachable.

Core packages to start with:

• athena: Core data structures and algorithms for manipulating map state in both client and server contexts.
• apollo: Core data structures and algorithms for manipulating game state in both client and server contexts.
• hera: The game engine and rendering layer responsible for visuals, animation, and scene management.
• ui: The design system underpinning the user interface, ensuring consistency and accessibility.
• docs: Documentation and playground assets to help developers learn the codebase and experiment with features.

Secondary packages that complement the core functionality:

• art: Asset handling and management for the client build.
• codegen: A piece of tooling to generate encoded actions and formatters when Action and ActionResponse definitions change.
• dionysus: AI code, blending client and server-side AI logic.
• hermes: Campaign-related data structures and algorithms, crucial for scenario and progression systems.
• i18n: Internationalization support to broaden accessibility.
• offline: An offline splash screen and related utilities for the app.
• tests: End-to-end tests to ensure reliability and regression safety.

The Greek Gods Naming Convention

A playful, yet practical, naming convention ripples through the repository: packages are named after Greek gods. Athena was the first, and the rest followed as the project expanded. This naming choice reflects a culture of curiosity and lighthearted creativity, but it also serves a practical purpose: it makes it easier to discuss and organize related modules across a large monorepo. The result is a codebase that is not only technically coherent but also approachable for developers across teams who may contribute rather than simply consume.

Assets and Open Source Policy

Athena Crisis is described as an open-core project. The core, non-content code—such as the engine, data structures, algorithms, rendering, AI, and the map editor—has open-source equivalents in this repository, with more than 100,000 lines of code available for examination, learning, and extension. However, assets like art, music, story content, characters, and other expressive elements remain proprietary to Nakazawa Tech KK and are not open source. The assets themselves are loaded remotely from Athena Crisis servers during testing and development. This clear division helps protect intellectual property while allowing the community to experiment with the codebase.

If you intend to build a commercial project that uses Athena Crisis as a foundation, you can do so. However, you must replace all content references to assets with your own and obtain licensing for any usage beyond what the codebase itself permits. This ensures that developers can learn from and reuse the underlying technology while respecting the original IP and asset rights held by Nakazawa Tech KK.

Sourcing, Syncing, and Code Ownership

Nakazawa Tech runs a monorepo strategy that synchronizes a portion of the open-source code with an internal monorepo. Code merged into the public repository is mirrored into the internal one, and the reverse is true as well. Athena Crisis consistently runs the latest code from the public repository in production, ensuring that the game’s live experience remains aligned with the community’s contributions and the most current improvements. The approach balances openness with controlled IP management for sensitive content.

Why Open Source?

Nakazawa Tech positions Athena Crisis as an open-core company project designed to show what is possible when core technology is shared openly. The decision to open source a substantial portion of the codebase is explained within a broader narrative about open source strategy. The project’s governance and community-facing posts explain why openness matters for learning, collaboration, and the evolution of the technology in public.

The open-source stance invites the community to contribute in meaningful ways—whether by improving core data structures, refining AI behavior, advancing the rendering engine, or extending the testing framework. It also invites developers to study and adapt the system for their own projects, whether for education, research, or the development of new games inspired by Athena Crisis.

Open Source Q&A: What’s Open and What’s Not

• What is open source in this project? More than 100,000 lines of non-content code are open source, including core data structures, algorithms, engine components, rendering, AI, and the map editor.
• What isn’t open source? The backend implementations for user management, databases, APIs, real-time spectating, server configuration, and app wrappers for Steam or app stores are not open source.
• Why open source at all? Nakazawa Tech views open source as a vehicle for collaboration, learning, and external improvement, while preserving ownership of content and some service-oriented components.
• How is the codebase used at Nakazawa Tech? A monorepo approach is used, with synchronization between the internal and public repositories to keep production deployments in sync with the latest public code.
• Why are some folders almost empty? To simplify dependency management with pnpm, many internal package.json files and the pnpm-lock.yaml are public, which aids cross-repo sharing. Some placeholders exist to keep the structure intact.
• Why the Greek gods naming scheme? It’s a pragmatic and fun way to organize packages and make the codebase approachable as it grows.

A Vision Realized: Content, Community, and Code

Athena Crisis embodies a philosophy where the engine, tools, and core data structures are accessible to developers who want to learn, build, or extend the base experience. The project demonstrates how to structure a modern JavaScript game around an engine that handles map state, game state, AI, and rendering with performance considerations appropriate for a turn-based strategy game. It also shows how a team can split responsibilities across multiple packages, enabling easier collaboration, testing, and maintenance while keeping the boundary between open core code and proprietary content clear.

For those who glimpse into the project’s public repository, the code reveals a careful balance between flexibility and discipline. The modular design makes it possible to test ideas, validate algorithmic improvements, and implement new gameplay features without disrupting the broader system. The design system in the ui package ensures that user interfaces remain consistent, accessible, and customizable, which is essential for any complex strategy game that must present information clearly under varying conditions.

The assets policy reinforces a practical reality: while the code can be examined, extended, and reused, the creative assets must be sourced deliberately and licensed appropriately. This separation helps protect the intellectual property embedded in the game’s art, music, and narrative while empowering developers to build new experiences atop the solid, shareable foundation.
