Hear how Sam Barlow and Half Mermaid conceived and then designed the multi-dimensional, decade-spanning series of interconnected Interactive Movies, IMMORTALITY.

Learn about the design processes and prototypes that allowed the team to explore the game ideas and structure. How the ambitious and layered story was outlined and researched, and how the team collaborated with notable screenwriters to tap into authenticity. How game design learning translates into the production and directing of the three movies worth of footage. Finally, what learnings other teams can take from this ambitious and boundary pushing title to apply to their own genres and game ideas.


Attendees will learn about Sam Barlow's process to evaluate ideas and hone a game design on paper; the tools used to build a complex narrative and outline it; how to prototype and test long before any final content is produced; and what developers can learn from the concentrated creativity of filmmaking.

Intended Audience

This is for anyone interested in breaking new ground in video games without losing sight of the medium's strengths, particularly anyone working with complex narratives or more freeform game structures and level designs.
