I have at least successfully started it and played two matches unranked. I run it through Lutris (Start Ubisoft connect from Lutris) and the start xdefiant through Ubisoft connect.

I followed some Indian guys tutorial on YouTube. It crashed two times and trying to start it a third time, Lutris gave an error sth was missing (don’t remember what exactly) and offered to install it. After that it worked but probably more coincidence than knowing what I did. The tutorial added two game execution properties and installed some windows dll through winetricks.
