Enjoying the game so far, but cant seem to even get close to preventing the submarine launched missiles from sinking my carrier. I aim for the front of the missiles which seems to be the weak spot (or the bullets lead down the rest of the missile in flight) but the guns overheat so quickly. I switch from the ship mounted gun to the helicopter mounted gun but always over a third of the missiles get through, and there are at least three waves. Any ideas or tips would be greatly appreciated.
