Don't let those boats get past your line of defense in Boat Invasion! In this tower defense game, there will be rivers that the enemy will use to be able to invade your territory and you must set up different towers in the riverbanks to successfully combat them and prevent them from ever setting foot in your place. There will be loops in the routes and you can use this to your advantage because you can spend less on towers if you place them on a spot where they can attack two times in one wave. There will be upgrades so save up! Boat Invasion is one of our many Strategy Games that we publish on TheGamerStop.com. This game is also tagged as a Tower Defense game.
