In August 2025, Chad delivered a new playable faction, YZY, for the hoi4-modding-den/Dens-HRE repository, expanding player choice and immersion in Hearts of Iron IV. He handled the full integration of YZY, including graphical assets, localization using yml, historical starting conditions, and a new leader, ensuring persistence through careful updates to game state and unit history files. Chad’s work demonstrated proficiency in Paradox Script and configuration management, with attention to asset pipelines and data modeling. The feature was delivered through Git-based collaboration, with minor edge-case fixes addressed during integration, reflecting a focused and well-structured approach to game modding.
