The new WaterWars iPad game from SpinIsland combines elements of classic pencil and paper gameplay and wide screen water battle action. This game is a lot of fun and, thanks to a few playing options, the kind of app you’ll want to play again and again
Water Wars is a FREE combat game play on water. Attack and destroy your opponent’s aircraft and ships by swiping with your finger across the screen to draw a straight attack line. If your attack line crosses the center of the opponent’s ship or aircraft, their ship or fighter jets is destroyed in an explosive ball of flames.
