Some Highlights:

SP campaign The SP campaign has a different approach than usual in two ways. First of all, we have focused on particular fighting units, with 2 units in each campaign. The second difference is the fact that we have integrated the skirmishes in the US SP campaign storyline. As our Store page mentions, the US campaign focuses on the 2nd Rangers and the 3rd armored division. As you may know, the 2nd Rangers did much more than take Pointe du Hoc on D-Day; they fought in Belgium and Germany as well. The 3rd armored division arrived in France a few weeks after D-DAY, and started making history immediately.

On the German side, the SP campaign follows the 3rd Fallschirmjäger division, which arrived in Normandy 4 days after D- Day, and 116th Panzer division. Both of these units were in the thick of it after D-Day and both fought until the end. The 4 skirmishes for the US faction will be integrated in the SP campaign, filling in the spaces in the linear storytelling. Basically this will give the player a 10 mission storyline.
