For this project, my responsibilities built upon those I held on the first Mercenaries game. I was deeply involved in the design and implementation of many systems, including: game structure, objectives, UI/UX, in-game cinematics, persistent open world systems (such as dynamic population and faction relations), and game state saving/loading. I also designed mission content and contributed to the story and writing.
I was the chief architect of all gameplay systems written in Lua script (including all of the aforementioned). In this capacity, I guided and mentored 15+ designers in the overall mission scripting effort. So much of the game was written in script that, in the final months, several programmers were drafted to contribute. I helped oversee these contributions.
