Game is in closed beta stage, it will be improved much after release. There will be mortars, artillery, engineers, flamethrowers and much more tanks. I love this game. Reto planned to increase battles up to 32x32 and even 64x64 with big beauty maps. Battles are not about pew-pew. Its requiers some teamwork and coordination between different classes of war units. Devs trying to keep authentic athmosphere: weapons, vehicles, armor, uniform. They will add USSR, Britain, Japan, Italy, whole theater of ww2 will be included. With each build i see how game grow up and become more and more complex. Those who like just usual pew-pew shooters better don't try this game you don't like it. There is a lot such shooter like CoD!
Ah, and one more important detail, developers are really listen opinion of community, new builds bring many changes inspired\suggested by users, gameplay, assault teams structure, structure of strategic commanders and many other shit!
