Barricade yourself in a tower, in a fort, or in an outpost, and shoot your enemies down before they reach the walls of your defensive structure. Prepare unbreakable defensive strategy, repel attacks of raiders, and fend-off waves of incoming zombies. Control military forces, set waypoints, firing signals, and focus fire on the incoming enemy! Go old-school, and choose medieval weapons and artillery, or pledge for more advanced defensive mechanisms like lasers and nuclear weapons. Our defense strategy is in your hands!
