## What it is
Chop Chop is an open-source action-adventure game demo built in Unity as part of Unity's collaborative Open Projects initiative. Development stopped in December 2021, but the full source code, art, and design remain available as a reference for Unity game development.

## Use cases
- study a complete open-source Unity game codebase
- learn how to structure a Unity action-adventure project
- find examples of Unity game architecture and conventions
- use as a starting point for a mod or game jam project
- learn Unity game development from a real project

## When to choose
- you want a real-world, community-built Unity game to learn from
- you need reference code for Unity project organization and conventions
- you want to fork or remix a small complete action-adventure game

## When to avoid
- you expect active development, updates, or community support
- you need a production-ready game engine or framework rather than a demo
- you work outside Unity or don't use C#

## Facets
- artifact type: application
- maturity: abandoned
- function: game-engine
- domain: gaming-tools, cross-platform
- platform: game-engine, cross-platform, windows
- tags: unity, action-adventure, open-source-game, community-project, game-demo, game-development, macos, linux
