Ultima Underworld returns as a fan-made Unity remake after 10 years of work

Fans have released Unity Underground after more than a decade in development, a Unity remake of Ultima Underworld.

The project adds new 3D models, animations, effects, and audio, but still needs the original game files to run.

Developers say the assets were handcrafted, though they used LLMs for some placeholder UI and audio work.

The release brings back a landmark 1992 dungeon crawler that helped shape modern 3D RPGs.
