## The project

Protocol 223 is a free-roaming virtual reality experience built around four dimensions: full-body capture, a mixed-reality environment, free movement and competition.

## My role

I worked on Protocol 223 as CTO and lead developer. My scope covered a significant part of the Unity VR development as well as leadership of the developers and artists.

My responsibilities included:

- the game architecture and networking layer;
- programming the motion-capture suit's microcontrollers;
- VR tools and tools for mapping the physical room to its virtual representation;
- Unity tools and tools for creating and dressing game levels;
- services used to operate the game, including cloud, database, API and game master application work;
- some of the visual effects.

This list describes my responsibilities without disclosing the project's detailed architecture, algorithms or internal processes.

## The central challenge

The most significant challenge was integrating the motion-capture suit and synchronizing the player's physical body with their virtual avatar.
