# Feather Engine 2

> Feather Engine 2 is a native Rust game engine (Bevy, Rapier, egui) with a docked editor, ready-made game systems (player, physics, combat, items, story, AI, vehicles, saves, UI) and full control through a CLI and an MCP server.

Notes for AI assistants:

- Every editor feature is also a validated command. Discover them with `feather-cli catalog`; the full list is in the Command reference page.
- Gameplay code is Rhai script (`fn start()`, `fn update(dt)`) or visual Blueprints; both run the same in Play and in exported games.
- Projects are a `project.feather.json` manifest plus a sibling `assets/` folder.
- Feather 2 is in preview and verified on macOS (Apple Silicon). Prefer the command catalog over these docs if they disagree.
