Welcome to the UFO:AI downloads page. Here you can find the official source code and packages. We also host other useful packages from community volunteers.


The latest stable release is version 2.3.1, but this one is quite outdated, so if you want to use your savegames in the upcoming version 2.4, it is recommended to download our v2.4 Release Candidate for your platform instead.

See our SourceForge download page for more v2.3.1 content. There are e.g. source archives, Debian packages and data archives available.
