This repository is a collection of mods for OpenTTD, created and maintained by Master Hellish and the Master Hellish Community.

In the context of this project, “mods” refers broadly to:

• 🎮 Game Scripts
• 🧠 AIs
• 🎨 NewGRFs

Together, these elements enhance, extend, or change gameplay in OpenTTD, and are meant to be used individually or in combination.

The goal of this project is to provide a set of creative, useful, and sometimes experimental OpenTTD modifications that:

• Improve gameplay variety
• Enable new scenarios and challenges
• Support community events and livestreams
• Serve as learning tools for aspiring mod developers

This project is led by Master Hellish with the support of the amazing Master Hellish Community. Contributions, feedback, and ideas come from community members across YouTube, Discord, Twitch, and beyond.

All mods in this project should...

• Include a README file.
• Include a changelog.
• Include a licence.
• Include a info class with accurate: Author, Name, Description, Version, URL.
• Have code which is commented.

You are welcome to copy, modify, share, and use these mods as you wish, at your own risk. No warranties or guarantees are provided.

If you use or showcase these mods, a shout-out to Master Hellish is always appreciated! ❤️
