Both presentations were originally slated for March 13th.
Two technical presentations by Bungie developers, focused on the creation and ongoing support of their upcoming shooter, Marathon, have been abruptly canceled at the Game Developers Conference 2026. According to the event schedule, both sessions were set to take place on March 13th.
The first canceled talk was titled “Automating Marathon: How Bungie Went from 10 Automated Tests to Over 100 New, Reliable Tests to Deliver a High-Quality, Stable, Live-Service Game.” It was scheduled to be presented by Senior Automated Test Engineer Jon Walhley.
This session was intended to detail the evolution of Marathon‘s automated testing system. Its description highlighted how the development team expanded their automated tests from 10 to more than 100, a move aimed at significantly boosting the stability and overall quality of the live-service title.
The second withdrawn presentation, “High-Performance Gameplay Networking for Marathon,” was to be delivered by Senior Engineer Alan Wiederman. This talk planned to delve into the technical solutions implemented to achieve a high-performance networking architecture crucial for gameplay.
