Inside Project Titan: Making an Open World Game with 4,000 People | Unreal Fest Bali 2025

In this session recorded at Unreal Fest Bali 2025, Sam Bass from the Epic Games Technical Content Team dives into Project Titan, the 64-square kilometer open world he helped build that became the setting for a 10-week, 4,000 person art jam before being completed and released by Epic as a sample project. In this talk, you'll learn about Titan's origins and the (tiny) team that built it; dig into the underlying technology and see how it could apply to your own projects; and gain a deeper understanding of large-world game development in Unreal Engine 5.
