This free repo turns Claude Code into an entire video game studio: 49 AI roles, from creative director to level designer to QA. Here’s what it is, how to install it and the first prompt to start your game.
Your first game with Claude Code Game Studios
Install the engine
Godot 4 (free), Unity or Unreal 5.
Clone the repo
A new folder for your game.
Open Claude Code and type /start
It asks where you’re at and guides you.
One-page brief
Minimal mode: the idea on one page, no mountains of documents.
Playable stories
It codes, opens the game, looks at it and saves a screenshot.

Three tiers, like a real studio
| Tier | Roles | Examples |
|---|---|---|
| Directors | 3 | Creative director, technical director, producer |
| Department leads | 8 | Game designer, lead programmer, art director, QA lead |
| Specialists | 23 | Gameplay programmer, level designer, writer, QA tester |
| Engine specialists | 15 | 5 for Godot, 5 for Unity and 5 for Unreal |
Each agent has its own responsibilities and limits: agents at the same tier consult each other, but they don’t make decisions for another department.
Setup in 3 steps
Before you start: install Claude Code, Git and Python 3, plus your engine. Godot is free: godotengine.org.
- Clone the repo into your game’s folder:
git clone https://github.com/Donchitos/Claude-Code-Game-Studios.git my-game
cd my-game
- Open Claude Code in THAT folder (the one with
CLAUDE.mdandproject.yaml), not in a subfolder:
claude
- Type
/start. It asks where you’re at (no idea, a vague idea, a clear design or a project already underway) and takes you to the right workflow.
The first prompt
Paste it after /start:
I want to make a small game in Godot 4: [your idea in one sentence]. Use minimal rigor mode, write me a one-page brief and a first playable story. Ask me as little as possible.If you’ve already settled on the engine, configure it with /setup-engine godot (you can add the version, for example /setup-engine godot 4.7).
The wildest part: fewer documents, better game
The author built the same game from the same brief at different levels of rigor and counted how many documents each one wrote before the first line of code. The one with 30 documents (almost an hour of paperwork) came in last in the rating from two blind reviewers and a playtest with one person. The one with a one-page brief did just as well or better.
That’s why the default mode is now minimal:
| Mode | What it requires | Who it’s for |
|---|---|---|
| minimal (default) | One-page brief, short documents, solo review | Small games, game jams, getting started |
| standard | 5 design document sections, light review | Mid-sized projects |
| full | 8 sections, full documentation, review by all directors | Teams and big projects |
It looks before calling anything done
A passing test doesn’t tell you whether the menu is drawn off-screen. That’s why any story that changes something the player sees doesn’t get closed until the game has been opened, looked at and a screenshot saved in production/qa/evidence/. This applies even in minimal mode.
The drawbacks
Heads up
It asks before writing anything. It’s collaborative, not an autopilot: the agents ask, give you options and nothing gets written without your sign-off. It’s normal for it to ask permission file by file.
- It eats through your Claude usage fast. There are many agents and the three directors request the Opus model. Start with a small game in minimal mode.
- You need a separate engine. The repo doesn’t include Godot, Unity or Unreal: you install them yourself.
- It’s not for your dream game on the first try. First make something you can finish in a weekend.
Checklist
- Claude Code, Git, Python 3 and the engine installed.
- Repo cloned into a new folder.
- Claude Code open at the project root.
- /start and the first prompt with your idea in one sentence.
- One-page brief approved and first playable story.
- Game screenshot in production/qa/evidence/.
