In this 2018 GDC session, Guerrilla Games' Ana Barbuta provides a retrospective of the victories and challenges faced when testing an ambitious open-world title like Horizon Zero Dawn.

It's a practical, insightful look at what unique obstacles come with testing and refining large virtual worlds, which are becoming more and more common in games. Barbuta also shared some fascinating details about the core elements and principles of Guerrilla's approach to QA, with specifics relating to the people involved, early engagement, communication, trust, agility and collaboration, processes, risk management, test strategy, tools, telemetry and post-launch support.
