XU4 is a remake of the computer game Ultima IV. The goal is to make it easy and convenient to play this classic on modern operating systems. XU4 is primarily inspired by the much more ambitious project Exult. XU4 is a cross-platform application thanks to SDL; it's available for Windows, MacOS X, Linux and more.
This project is currently under development and beta releases are available. The game is fully playable from beginning to end. The very latest source code can always be accessed from SVN. Please post a message in our discussion forum if you are interested in helping.
