Company of Heroes 2 is returning to the setting of Company of Heroes 1 with The Western Front Armies, a standalone expansion that's coming out in June for $20. It includes two armies: the US forces and the German Oberkommando and eight new multiplayer maps set in the green, unfrozen lands of the Western Front. There are no single player missions or Theater of war Scenarios mentioned, so it looks like an expansion designed to feed the multiplayer scene, which has been quietly warring away since launch last year.
Though Western Front Armies is standalone, it'll share a multiplayer pool with Company of Heroes 2, which means whatever combination of the two you own, you can be automatched onto any of the 31 maps alongside any army. Buying the original game or the expansion will make their included armies playable, and let you create custom games with the included maps. Sega also note that the armies will be available separately for $12.99 each.
There's also mention of a "new progression system" that will let you unlock "unique content" that'll let players "dive deeper into the tactical and strategic aspects of the game". I don't know what that means, but it might have something to do with the tiny unit upgrades and skins you can unlock with the current experience system.
Here are a few shots from the Xpack. Shermans! Paratroopers! I'm having happy flashbacks to the first game.
