There was a download of UFO:AI 2.5 on the developer's website when we last checked. We cannot confirm if there is a free download of this software available.

This free PC software was developed to work on Windows XP, Windows XP Professional, Windows Vista, Windows 7, Windows 8, Windows 10 or Windows 11 and is compatible with 32-bit systems. The actual developer of the free software is UFO:AI Team. The tool can also be called "UFOAI".

Ufo.exe, ufoded.exe or ufo_ded.exe are the common file names to indicate the UFO:AI installer. We recommend checking the downloaded files with any free antivirus. The most popular versions among the software users are 2.5, 2.4 and 2.3. The program is included in Games.

From the developer:

UFO: Alien Invasion is a squad-based tactical strategy game in the tradition of the old X-COM PC games, but with a twist. Our game combines military realism with hard science-fiction and the weirdness of an alien invasion. The carefully constructed turn-based system gives you pin-point control of your squad while maintaining a sense of pace and danger.

You may want to check out more software, such as FreeOrion, Warlords Battlecry III or Gunbound, which might be similar to UFO:AI.
