Will Warhammer 40,000: Dawn of War III work on my Linux distro?
Warhammer 40,000: Dawn of War III has been fully tested on Ubuntu 16.04 and 16.10. For the best gameplay experience, we recommend you use one of these distros.
The game should also work on other recent versions of Ubuntu, and may also work on other Linux distros; however, as the game has not been tested on these, it is possible that you will encounter performance and gameplay issues, and we do not currently offer support for other versions or distros.
