RainGameDev/UnTurned ? reverse-engineered prompt

Build me the Unturned game project so I can open it in Unity, press play, and get into the main game scene.

It should be a free open world zombie survival sandbox where the player can explore, collect items, fight zombies, and test gameplay inside the editor. Set it up so the project opens cleanly in the right Unity version, and make sure the startup scene loads from the game startup scene mentioned in the repo. If anything depends on Steam assets or installed game files, wire it up in the simplest way that works and let me know what needs to be present locally.

I mostly want this to be ready to run and easy to iterate on, so if there are obvious setup issues, missing references, or editor problems, fix those too. Keep it practical, and if you need current Unity or Steam docs to confirm anything, look them up online.
