 An **unofficial, non-commercial fan remake** of Arknights' seasonal auto-chess tower-defense mode *Stronghold Protocol: Alliance*, 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 full bundle `Stronghold-Protocol-v<version>.zip` (~430 MB, all the art inside) from [Releases](../../releases/latest) — or the lite one, `…-lite.zip` (~22 MB), which downloads the art (~460 MB) on its first start — 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 ~460 MB of art from public mirrors, the emotes and the how-to-play pages included; the official 3D board, some official HUD icons, two enemy models and 39 summon models are extracted from a local Arknights client — without one the game uses the 2D board and look-alike stand-ins (the summons show their avatars), and a server can copy `public/assets/local/` and `data/local-assets.json` from the full bundle of the same version).
+- **Languages:** Chinese (the default), English, 日本語, 한국어 and 繁體中文 — switch on the title screen or in Settings. Game texts come from the official clients; the Japanese, Korean and Traditional Chinese interface strings are machine translations (corrections welcome: [docs/I18N.md](docs/I18N.md)).
 - **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).
