## What it is
The full source code and Unity project for Unturned, a free open-world zombie survival sandbox game. It serves as an SDK allowing players and modders to rebuild, modify, or totally convert the game using the Unity editor.

## Use cases
- build and run Unturned from source in Unity
- create total conversion mods of Unturned
- add custom gameplay features like new weapons or mechanics
- learn how a shipped multiplayer survival game is structured
- make custom maps and Steam Workshop content

## When to choose
- you want to modify or extend Unturned with code-level changes
- you want to study a real, shipped Unity multiplayer game's source
- you're building a total conversion or dedicated mod project on top of Unturned

## When to avoid
- you want a general-purpose game engine (use Unity itself)
- you need a lightweight modding-only workflow without the Unity editor
- you want a permissively licensed codebase to reuse in your own game (license is custom)
