I was the sole Narrative Designer on Halo 4's campaign. It was my responsibility to implement all of Halo 4's narrative content and pace it all out. Additionally, I provided writing support for ambient VO, domain terminals, and later for Spartan Ops missions.
One of my narrative design duties in Halo 4 was determine a cadence for and execution of Cortana's rampancy. In addition to the major events in the story that illustrated her gradual falling apart, I had tools at my disposal to integrate into mission design including visual and audio effects. I paced these out in a way that created a gradual built and punctuated key moments.
