BRUTAL is used in RocketWerkz's Kitten Space Agency and was provided as the foundation for Waylith, the engine built for Ludeon Studios' RimWorld. It is open source under the MIT License and free for commercial works, with conditions: credit, copyright and logo on the startup screen, and the NOTICE file.","whyItMatters":"Hall is positioning BRUTAL as an alternative to Unity and Unreal Engine on contract terms, royalties, and account restrictions, and RimWorld's move to an engine built on it gives that argument a working reference.","webCardHtml":"\u003cp\u003eBRUTAL was developed in secret in-house as RocketWerkz\u0026#39;s own custom framework before the studio decided to release it for free. Hall cited contract issues with widely used engines, including royalties, terms of service, and account restrictions, and technical workarounds needed to implement certain features, as reasons to offer developers another route. The framework is not a general-purpose tool for all game production; the name reflects its origin as a template that anticipates specialized uses. Source code and terms are on GitHub.\u003c/p\u003e","blueskyPost":"Dean Hall's RocketWerkz has released the BRUTAL framework and its source code.
