Jakub Czaplicki developed a flexible starting army feature for the arcane_artillery.tex scenario in the Homm3BG-mission-book repository, focusing on enhancing player customization in game design. He restructured the scenario’s initial army selection, allowing players to choose specific Bronze Units rather than receiving a preset mix, and introduced an additional option for larger starting forces. This work involved scenario editing using TeX, with careful attention to documentation and change traceability to support future balance experiments. Over the month, Jakub concentrated on feature delivery rather than bug fixes, demonstrating depth in scenario logic and a methodical approach to maintainability and future extensibility.
