Sitting in a tent during WW2 and all you have is a map and a radio, it's time to shout some orders and hopefully win. You quite literally do shout your orders too, you need a microphone for this as it's using speech recognition.
While not a unique idea, a few others have done it, for it to be in a strategy game like this definitely is a bit more unusual. It's real-time too and as you get verbal reports back you then need to act fast and start making some decisions.
Thing is, you don't always get an accurate picture of what's going on (such is the way in war) so the information you get will be incomplete and sometimes perhaps a little confusing. You also have to deal with troops personally too with ammunition, morale, camouflage, sight and stamina all being simulated. There's a lot more going on too as terrain type will heavily influence battles, you can try and do an ambush with a small team and it will include what they say are 100s of historical photos, documents and video so you can "Learn how soldiers lived throughout the war, and gain a better understanding of their experiences.".
Developer Foolish Mortals has been working on it for a few years now, and it sounds like it's really coming together nicely with it possibly releasing next month. You can wishlist/follow it on Steam.
