## Requirements & limits

- **Prerequisites:** Requires an owned Dungeon Siege installation; Windows and Linux builds are linked. Source builds need .NET 10; Linux needs OpenGL 3.3 and internet multiplayer additionally needs OpenSSL 3.
- **Testing evidence:** The README calls this alpha software. It reports campaign progression to the final boss since v0.4.0, with Bink movies, interior lighting fidelity and combat balance still open.
- **License:** Code is GPL-3.0-only; original game assets are not bundled. Multiplayer uses Epic Online Services under separate SDK terms.
