The free Project Titan sample project has just dropped on Fab, along with tons of supplementary content! You can find out more from the official blog here.

For those of you unfamiliar with the project, here is the official description:
In March 2024, Epic Games unveiled Project Titan, a groundbreaking global Unreal Engine 5 art jam. This initiative brought together contributors from around the world to collaboratively create a massive, open-world environment over the course of three months.
Unlike traditional Unreal Engine samples, Project Titan is not solely focused on best practices. Instead, it celebrates the achievements of the participating artists while demonstrating the accessibility and collaborative potential of Unreal Engine.
Designed to support a wide range of platforms, from mobile devices to high-end PCs, Project Titan features an expansive 8×8 km open-world map, a Mover-driven player character with diverse movement modes, and an array of plugins and world-building tools developed specifically for the art jam.

This was a total labor of love from both the folks at Epic and the amazing community that participated – go forth and enjoy!
