I have made it to controlling half the map, the choke point midway where they have a town at the lowest peak of the mtns and I cant do. They simply build a continuous line of units. Its insane. I try to hold the line and manage resources to build up, but they are doing the same up north. I got he little down by the water where they advise to stay out the north. I do this, I do not press the northeast pass. However endless horde comes down it. Rage quit like 10 times tonight. Any tips???
