During their two-month contribution to the wesnoth/wesnoth repository, Schattenkopie focused on both visual asset updates and gameplay balance. They replaced civilian sprites with juvenile-specific assets for the Saurian Juvenile unit in The Deceivers Gambit campaign, enhancing animation and ensuring color consistency through 2D art and asset management. In a separate feature, they tuned arcane resistance values for Drake units by updating configuration files, supporting maintainable balance changes. Working primarily with configuration management and 2D art, Schattenkopie’s work addressed campaign fidelity and gameplay consistency, demonstrating depth in both visual and mechanical aspects without introducing bug fixes during this period.
