Worked on the CombatExtended-Continued/CombatExtended repository to deliver two feature patches focused on expanding in-game trading and ammunition diversity. Leveraging XML and game modding skills, introduced new stock generators for lasgun ammunition and broadened ammo types across multiple expansions, including Talons of the Emperor and Angels of Death. The approach centered on data-driven XML patching to ensure compatibility and consistency between standard and caravan traders, refining stock generation bounds and price ranges. These changes enhanced the in-game economy by providing richer trading options and more predictable inventory behavior, while maintaining cross-expansion configuration management and clear, Git-tracked patch-level delivery throughout development.
