PC versionPC100% Fans have made a PC version. Some are still early, so read the project page first.
Fans took Underworld Revisited apart and rebuilt it so it runs natively on a computer, often with widescreen, higher frame rates and mods. Here is the project we know about:
An open-source reimplementation of Ultima Underworld: The Stygian Abyss (1992) in Unity, faithful to the original's rules. Fully playable. Needs the GOG version; no game data included.
