During July 2025, Mace contributed to the ARF-SS13/coyote-frontier repository by developing the new Turncoat shuttle feature. This work involved designing a complete map layout, defining shuttle entities, and configuring core properties such as name, description, price, and class using YAML. Mace also refined the user interface by adjusting relevant buttons and extended the cargo bay to support the new shuttle’s operations. All changes were consolidated into a single, descriptive commit to ensure traceability and facilitate potential rollbacks. The work demonstrated focused application of configuration management, game development, and level design skills within a concise, well-scoped project.
