X@COM Alpha Demo: Download***
Current Version: 0.17.130815r9.4 (changelog)
Platform: Windows
File Size: 9.89 MB
***The demo above only includes the original/older missions--if you've played before check for newer missions as stand-alone mods below. (Newer missions also include more features and full sound.)

You must have the latest runtime DLLs (msvcp100.dll, msvcr100.dll) to run the game. If X@COM complains about DLL files, download and install the MSVC++ 2010 Redistributable Package (x86). After clicking "Download" it will list multiple versions, and the one you need is "vcredist_x86.exe". (Also make sure the game is run with admin rights so that it can write to its own directory, otherwise it may crash.)

For Linux users:
The only VC++ runtime DLLs actually needed are those mentioned above. If you're using Wine and are unable to install the redistributable, you can run the command "winetricks vcrun2010," or download those two files from the web and put them in Wine's "windows/system32" directory to play.


These are stand-alone mods and do not require a copy of the core game to run. Simply decompress and run the included .bat file.

  • Warning if you're coming from a newer version: Some mods are not powered by the latest version of X@COM, and therefore may not take advantage of all the features currently available.
  • Anyone interested in modding should join us on the forum.
  • Linux/Wine and some Windows users may find that your system does not like the provided batch file used to run mods, in which case you can find another batch file by the same name in the game directory itself and run that instead, which should work.
