Ground of Aces Modkit

Developer Preview - use at your own risk

This modkit is a developer preview. Everything here - the docs, the tools, the rules and the modding features of the game itself - is subject to change without notice. Anyone can read this site, but the kit itself is currently by invitation only - see "Get access" below. You use it at your own risk: back up your saves before you try a mod, and do not rely on anything here staying the way it is.

Ground of Aces

Build your own missions, quests, events, maps and more for Ground of Aces. No Unity, no compiler - a mod is a folder of ordinary files: JSON, CSV, Python, models and images. And if you like, an AI agent writes them for you.

I have never programmed Start here. Your first mod takes five minutes and needs nothing but the game and a text editor. Tools and AI come later, if you want them.

I want to dive straight in You know your way around files and folders. Copy an example, change it, reload - done.

I use an AI agent Claude Code, Codex or the open-source OpenCode: clone this repository, start your agent in it, and describe the mod you want. The agent knows the rules.

Get access

The documentation is open to everyone. The modkit itself - the repository with the examples, templates, validator and AI rules - is private during the preview. To get access, send a short email with your GitHub username to jan@blindflugstudios.com or moritz@blindflugstudios.com. Tell us what you would like to build - we love to hear it.

How it works in one minute

  1. Open the game, go to Main menu → Mods → Open folder.
  2. Put a mod folder there - for example a copy of one of the examples.
  3. Back in the game, return to the main menu, open Mods, press Refresh (so the game notices the new folder) and load your save.

That is the whole loop - see Testing and reloading for the details. Everything else on this site is about what you put into that folder.
