# huginhelm Godot 4 starter kits

> Godot 4 (4.7) game starter kits / project templates in typed GDScript: factory & automation, survival crafting, tower defense, 3D real-time strategy (RTS), 2D destruction. Each kit has a free MIT "Lite" edition on GitHub and a paid "Pro" edition (commercial per-seat EULA, prices in EUR) on itch.io. All kits run headless tests via `bash tools/run_tests.sh`.

Each Lite repo contains AGENTS.md and llms.txt describing structure and extension points. Pro keeps the same API as Lite, so projects upgrade without code changes.
