The Ur-Quan Masters - Extended Edition
Welcome! This project is a modest, unofficial fork/sub-project of The Ur-Quan Masters, aimed at enhancing the single-player game's atmosphere, story depth and continutity. No changes were made to the main plot, but various plot elements have been added to make the game world seem that much more "full", and gameplay more satisfying. If you've played the game before, this means that it's the same game, just with more side-plots and whatnot to find/explore. If you've never played the game before, this version is every bit as feature-complete as the "official release", but with some extra features.
A full list of changes is detailed here
