Great Game, Build up Gameplay, Great for tacticians, but here's a Protip: Always have your Sales Area maxed, and Zombies will die out each day so stay on the attack Don't wait around unless absolutely necessarily, and best of all If you have equal or less odds in Att v. Def or vice versa, you WILL be eliminated, so when u get to russia, it gets Fun, but Eventually you will conquer the world!
