Sea Ships Attack! Base Defense!

Command the river batteries in Sea Ships Attack! Base Defense! Enemy vessels push through canals and river lanes toward your base, leaving you to hold the line with shore guns before the defense collapses. The campaign runs through dozens of career missions, and later maps send in larger hulls with heavier firepower. Boats, warships, and submarines don't approach the same way, so the water route changes from an easy opening to a packed naval siege.

How to play?

Buy cannons with your cash, then drag them onto the round pads along the bank. Before a wave arrives, fill the best firing spots first so your guns meet ships early on the route. Different turrets fire with their own strengths, which makes placement more useful than stacking the same weapon everywhere. On some missions, several waves arrive in one battle, and the number of targets changes from round to round. Stronger ships pay more money when they sink, giving you faster access to heavier guns. Destroy enough attackers, and new weapons unlock sooner. If an enemy craft slips past your line and hits the base, you lose lives. Run out of lives, and the mission ends.
