It looks like Sega is really poised to bring the games in its catalog to Linux and they have released a new game for the open source platform, with the help of Feral Interaction, a company that specializes in porting games from Windows to other platforms.
“Ready yourself for heavy combat on the Western Front with the US Forces and the German Oberkommando West, bringing an unprecedented level of realism to multiplayer warfare on Mac and Linux. Company of Heroes 2: The Western Front Armies will break out on Steam for Mac and Linux on January 28th, followed by the Mac App Store soon after,” Feral devs wrote on their website.
The Western Front Armies expansion pack actually contains two armies, US Forces and Oberkommando West. The really good news is that it doesn’t require Company of Heroes 2, so it’s a stand-alone pack.
