UFO2000 is free and opensource turn based tactical squad simulation multiplayer game, heavily inspired by the famous UFO: Enemy Unknown and providing a very similar reimplementation of its tactical part.

Currently UFO2000 has its own basic set of fan-made graphics which is included in UFO2000 distribution by default (see screenshots). But those who also have a copy of UFO: Enemy Unknown game (there are plenty of places to buy it nowadays), have the possibility to use the original graphics from it for extending UFO2000 with additional maps, weapon sets and units.


UFO2000 is written in C++ language with Lua scripting and is known to compile and run on Linux and Windows systems.

Right now only human vs. human multiplayer is supported. You may find human opponents much more challenging than AI from the original game.


Our forum is the primary source of information for UFO2000 players, here you can ask questions, discuss the game with the other people and find opponents to play.
If you have found a bug in the game, please report it on our bugtracker.
If you have some software development or artwork creation skills and want to contribute to the development of the game, please visit this forum section.
You can also join IRC chat at irc.freenode.net channel #ufo2000 to communicate with ufo2000 developers in realtime.
Mailing list is now also available: http://groups.google.com/group/ufo2000
