It seems like we could have a pol support for this. I was not able to find any reference to it in the forum. As anyone tried to install it from Steam ? I have the original game but it was never an option under wine because of "Games for Windows - LIVE"(GFWL) - A required program for Warhammer 40k. .NET 3.5 sp1 is required.".
However the "Retribution" version dropped GFWL.
