Afternoon all, Im playing through my 2nd game of stratagy at the moment, the first one I caught the carrier with 5 islands and killed it with my shells on my carrier.. Very easy? What creates the different levels of defence on islands, and how is it possible to see how close the enemy is to taking your island? Everytime I go and have a look nothing is happening, then some time later its in enemy hands... Thanks,
