-An **unofficial, non-commercial fan remake** of Arknights' seasonal auto-chess tower-defense mode *Stronghold Protocol: Covenant*, played in the browser: solo, or 1–4 player co-op (AI teammates can fill seats). Combat is simulated in each player's browser, so a low-power PC can host.

 - **Run:** download the all-in-one bundle from [Releases](../../releases/latest), install Node.js 22 or 24, then double-click `scripts\start-windows.bat` (Windows) or run `./scripts/start.sh` (macOS / Linux) and open <http://localhost:3000>. From source: `npm install && npm run setup && npm start` (setup downloads ~250 MB of art from public mirrors; the official 3D board needs a local Arknights client to extract, otherwise the 2D board is used).
 - **Play with friends:** create a co-op room and share the 4-letter key or the `?room=KEY` link. On a LAN, use the address printed at start; otherwise use a virtual-LAN tool, a tunnel or a VPS — see [docs/DEPLOY.md](docs/DEPLOY.md).
