Bert Oostveen enhanced the cmss13-devs/cmss13 game codebase by developing a user-facing headset examination feature that displays all available radio channels in a dynamic pop-up, triggered exclusively by direct user input. This approach, implemented in DM and leveraging object-oriented programming, improved both usability and security by preventing remote exploitation of the UI. Bert also addressed equipment rank inconsistencies by assigning default paygrades to previously unranked presets, ensuring accurate in-game identification and consistent radio display. The work demonstrated a focus on maintainability and stability, combining targeted bug fixes with thoughtful UX improvements to align in-game assets with expected business logic.
