Awsome game
This game is awesome, it made me think of Company of Heroes.
I beat the Brittish campaign :) lost only 1 battle (but came up with a different strat to tackle it in the next try). It got a little laggy when there were many units on the field but that can't subtract to the score cause I think it has more to do with my pc then with your game. 10/10
To people who think this game is too hard: Go for all the ani tank upgrades so you can kill them easily in later battles. To take over trenches just stack up on assault teams in your trench and then send in a riflemen squad and when the riflemen squad is in the trench they will automaticly go out because it's full, at that moment send all the assault teams out of the trench and watch your men take over the next trench :)
For the last battle I chose not to send in troops but just bomb their morale down so they surrender and it worked. Just build a tank and a riflemen squad when you need to fend of some guys who escaped your bombings. I hope it helps you guys to get further and enjoy the game more.
