Iain developed a tier-based antagonist rules and configuration system for the tgstation-operations/server-config repository, focusing on expanding event and role variety while enabling dynamic difficulty scaling by population. Leveraging skills in configuration management and game design, Iain implemented an import workflow for antagonist rule sets and established a scalable architecture to support future expansion and efficient tuning. The work was delivered in TOML, emphasizing maintainability through clear commit messages and organized repository structure. Although no bugs were fixed during this period, the depth of the feature work provided a robust foundation for ongoing improvements in server configuration and gameplay balance.
