High Concept

My Fallout 4 mod, "The Longevity Zoo" tells two chapters of a story set in the Fallout universe. Each chapter had its own development cycle that spanned 8-10 weeks. I created the world space from scratch in Creation Kit, scripted over 100 events in the Papyrus language, wrote a cast of eight significant characters, and designed a computational system to enhance the narrative.

Chapters one and two had slightly different production goals: while chapter one was intended to appeal to a wide range of Fallout players by incorporating a breadth of Fallout 4 conventions, chapter two dove deeper into narrative systems and demonstrated the computational narrative potential of Creation Kit.
