Feral Interactive says The Western Front Armies game is now available on Stream for Mac OS X and Linux systems, and is coming to the Mac soon
The Western Front Armies expansion pack contains two additional armies: the versatile US Forces and the highly experienced Oberkommando West, as well as eight new maps set in the French and Belgian countryside. The Western Front Armies is available on Steam as a standalone game that offers a great entry point to Company of Heroes 2’s multiplayer. It can also be used with the Company of Heroes 2 base game.
On the Mac App Store, The Western Front Armies will be available as an in-app purchase, requiring the base game Company of Heroes 2 in order to play.
